Something strange has been reported swimming in the Gulf of Mexico, and five additional eyewitness accounts are making the mystery even more intriguing.
Last week’s Dark Outdoors® and Higher Calling Wildlife investigation into possible venomous sea snakes in Gulf waters attracted more than 10,000 views. Now new accounts, including one dating back to 1963, are raising fresh questions about what people have encountered beneath the surface.
One witness claims he captured a mysterious black-and-white-ringed snake near Sanibel Island, Florida, in 1963 and showed it to a park ranger.
Another describes pulling up a crab net near the Port of Pascagoula, Mississippi, containing a banded snake-like creature with a paddle-shaped tail.
Other witnesses from Florida and Alabama have reported unusual animals swimming in coastal and offshore waters, including brown snakes and yellowish creatures with strange tails.
Some of these descriptions bear a resemblance to highly venomous sea snakes and sea kraits found in other parts of the world.
But there’s a problem.
True sea snakes have not been verified as inhabitants of the Gulf of Mexico.
So what are these people seeing?
In this new investigation, I examine five intriguing eyewitness accounts and explore possible explanations involving spotted snake eels, chain morays, marine ribbon worms and native Gulf Coast watersnakes.
Could these encounters involve unfamiliar native wildlife, mistaken identities or exotic animals somehow reaching Gulf waters?
With Halloween approaching, it’s a fitting time to explore one of the Gulf Coast’s stranger wildlife mysteries.
The most fascinating wildlife mysteries aren’t necessarily those involving unknown creatures. Sometimes they’re encounters that challenge what we think we know about familiar environments.
These eyewitness accounts raise intriguing questions, but they don’t establish that venomous sea snakes inhabit the Gulf of Mexico. Answering that question will require convincing photographic, video or physical evidence.
Dark Outdoors® is dedicated to examining unusual encounters in the natural world, separating documented facts from speculation and exploring the mysteries that sometimes emerge where people and wildlife cross paths.
Have you ever encountered a mysterious snake-like animal while swimming, fishing or boating in Gulf waters? Share your experience. Photographs, videos and detailed descriptions could help shed light on this extraordinary mystery.

The chupacabra began as a blood-draining monster in Puerto Rico. In Texas, it became something very different. After years of investigating strange canids—and actually retrieving one alleged chupacabra carcass—I believe science explains much of the mystery. But maybe not all of it.
By Chester Moore
I have a chupacabra skull.
At least, that’s what most people would have called the animal it came from.
The skull has been in my possession for years, the remains of a bizarre, virtually hairless animal recovered after a flash flood. Its body had grayish, wrinkled skin, and its proportions looked strange enough to make anyone encountering it in the woods wonder exactly what they were looking at. I eventually went into the field and retrieved what remained of the carcass.
OLYMPUS DIGITAL CAMERA
Do I believe I have the skull of some undiscovered bloodsucking monster?
No.
But that doesn’t make the story of the chupacabra any less fascinating.
In fact, the deeper I have gone into the subject, the more interesting it has become.
The chupacabra is unusual among famous cryptid stories because its modern legend isn’t particularly old. Reports exploded out of Puerto Rico during the 1990s, where witnesses described something very different from the hairless, four-legged creatures that would eventually become known as “chupacabras” in Texas. Early Puerto Rican reports described something far stranger, sometimes almost alien in appearance, associated with livestock allegedly drained of blood.
By the time the legend reached Texas, the monster had changed.
Listen: The Horror and Science of Chupacabra
I recently explored this strange intersection of wildlife, folklore and firsthand encounters on a special episode of my Dark Outdoors podcast, “The Horror and Science of Chupacabra.”
I get into the famous sightings, the Texas “blue dogs,” mange, coyotes, wolves and hybrids—and the strange skull that has been sitting in my possession for years.
The episode gets into something I’ve come to believe after years of looking at alleged chupacabra photographs and reports: a monster can be very real without being an unknown species.
When Mange Creates a Monster
Take a coyote and remove almost all its hair. Let disease and starvation reduce its body weight. Expose the ribs, exaggerate the appearance of the legs and ears and alter the texture and color of its skin.
Now put that animal at the edge of someone’s property at 2 a.m.
Shine headlights on it.
Suddenly, one of North America’s most familiar predators doesn’t look familiar at all.
Severe mange can transform coyotes, foxes, raccoons and domestic dogs into animals that look shockingly different from healthy members of their species. Hair loss changes our perception of body proportions. Ears appear enormous. Legs seem unusually long and thin. Tails can become almost ratlike, while poor physical condition can produce a stumbling or unusual gait.
That’s important because the animal most commonly presented to me as a Texas chupacabra is a coyote.
Foxes can look even stranger. Their naturally prominent ears become exaggerated when most of their coat disappears, and their eyes can appear enormous when illuminated at night. Even raccoons can become almost unrecognizable after severe hair loss eliminates the familiar mask and bushy coat.
I’ve seen reports presented as mysterious creatures that were clearly animals we already know.
But I’ve also experienced firsthand how convincing the illusion can be.
The Night Something Charged Me
One night I was near a wooded area where I had been conducting red wolf research. I saw something moving low through the brush and initially couldn’t identify it. After I made a howl, the animal answered.
Then it came into view.
In the moonlight I could see an extremely skinny animal with large-looking ears. It circled, growled and eventually ran toward me, getting perhaps 10 or 15 yards away before retreating. When I finally got a good look at it, the mystery disappeared.
It was a domestic dog with an extreme case of mange. I estimated roughly 75 percent of its hair was gone.
But imagine someone else having exactly the same encounter.
You’re standing in the woods at night. Something nearly hairless emerges from the darkness, growls and charges you. You see huge ears, a gaunt body and exposed skin illuminated by your flashlight.
If you’ve heard the stories, you’ve just encountered a chupacabra.
That’s how legends can grow around real animals.
Then I Got a Call About a Body
My strangest connection to the chupacabra mystery began with my friend David Clever.
David encountered the body of an unusual animal following a massive flash flood. When he first saw it, the carcass was bloated and floating in a pool. When he returned later, much of the decomposition process had progressed, but the remains were still there.
He described an animal with no hair, grayish wrinkled skin and body proportions that appeared unusual. Eventually, David contacted me while I was doing research in the Texas Hill Country and asked if I wanted to retrieve what was left.
Of course I did.
I went out and recovered the remains.
And I still have the skull.
Looking at it now, I don’t believe I discovered an unknown species. My best assessment is that it belonged to a large coyote or a medium-to-large domestic dog, although the possibility of some degree of canid hybridization is interesting given the history of wolves and coyotes in the region. What I don’t believe is that hybridization itself explains the strange hairless appearance.
Mange does that very effectively.
The Strange Texas “Blue Dogs”
Texas added another layer to the chupacabra legend when strange hairless canids began attracting widespread attention.
These animals are sometimes called “blue dogs” because of their unusual gray-blue skin.
That appearance has helped fuel speculation that they represent an unknown canine, some unusual hybrid or perhaps the real identity of the chupacabra.
But research discussed in my podcast points toward a far less supernatural—and biologically fascinating—explanation.
Work cited in the transcript from researchers examining alleged chupacabra specimens identified animals including raccoons and domestic dogs. All suffered from mange, with extremely limited hair, thickened skin and a dry, wrinkled appearance. The discussion also noted secondary bacterial infection associated with heavily damaged skin and the unusual coloration observers sometimes report.
That combination can produce an animal that looks like it shouldn’t exist.
But it does.
What About Wolves and Coyotes?
There is another component of the Texas mystery that deserves attention: canid genetics.
Coyotes and wolves have a complicated genetic history in North America. Hybridization has occurred in different populations, and that can produce animals whose physical characteristics don’t always match the textbook image of a coyote or wolf.
That does not mean wolf-coyote hybridization creates chupacabras.
The transcript specifically addresses that misconception. Whatever genetic mixing may occur among canids, I don’t believe hybridization explains why these animals lose their hair and develop the bizarre appearance associated with Texas chupacabra reports.
Mange remains the far more compelling explanation.
But What About Puerto Rico?
This is where I hesitate to declare the entire chupacabra mystery solved.
The original Puerto Rican story isn’t identical to what developed later in Texas.
The very name chupacabra—”goat sucker”—grew out of reports involving livestock allegedly attacked and drained of blood. The legend exploded during the 1990s, but accounts of mysterious livestock deaths and supposed blood-draining creatures in Puerto Rico preceded the famous chupacabra wave.
Descriptions also evolved dramatically.
The original creature of Puerto Rican folklore could be portrayed as something almost alien. The Texas version became a strange hairless canine.
Those may be two very different phenomena that acquired the same name.
That’s why I’m willing to say I think I know what most Texas chupacabras are without pretending I’ve explained every unusual report ever associated with the name.
The Chupacabra Is Real—Just Not the Way You Think
My position on the chupacabra might sound contradictory.
I think the chupacabra is real.
I just don’t think most of the animals being photographed, filmed and found dead in Texas represent an unknown species.
They’re real animals suffering from real conditions that can transform them into something almost unrecognizable. In many cases we’re probably looking at coyotes, foxes, raccoons or domestic dogs suffering from severe mange. That’s also the conclusion I reached about the mysterious skull in my possession.
But knowing that doesn’t make encountering one at night any less unsettling.
I’ve had one charge me.
I’ve retrieved the carcass of another.
And I have its skull.
Sometimes the most frightening creatures in the woods aren’t monsters at all.
They’re familiar animals that, for one reason or another, no longer look familiar.
Hear the complete investigation and my firsthand stories in “The Horror and Science of Chupacabra” on Dark Outdoors.
A snake breeder walked into my office carrying a kingsnake.
Before he left, he told me a story I haven’t forgotten.
He noticed a photograph of a banded sea krait hanging on my wall. These are highly venomous marine snakes from the Indo-Pacific, far removed from the waters off Texas.
He looked at the photograph and told me he had seen one.
According to his account, he had kayaked offshore near High Island, Texas, to fish around a rig. There, swimming in Gulf waters, he encountered what he believed was a banded sea krait. He described the animal as four to five feet long, distinctly banded and possessing something particularly important—a paddle-like tail.
It would have been easy to write the encounter off as mistaken identity. Except his description immediately reminded me of another strange report.
Two anglers I know had been fishing around the 18-Mile Light on Sabine Bank when they saw a long snake swimming at the surface. They described it as bluish-white and black-striped, approximately five feet long.
And they described a paddle-like tail.
Now I had separate encounters from the same general region of the Gulf involving people familiar with snakes and describing remarkably similar animals.
That was enough to make me start digging.
Since then, reports of strange snake-like animals have come to me from other parts of the Gulf Coast, including Alabama and Florida. Some may ultimately have very ordinary explanations. Eels and other elongated marine fishes can look remarkably snake-like, and native snakes can certainly enter coastal waters.
But what about the reports that aren’t so easily explained?
And if a highly venomous marine snake from another part of the world somehow reached the Gulf, is there a mechanism that could get it here?
That question took my investigation into international shipping, ballast water and the long history of animals being transported far outside their natural ranges.
My new video, “Venomous Sea Snakes in the Gulf? Investigating the Reports,” examines the eyewitness accounts and the possibilities behind them.
To be clear, this is not evidence that sea snakes are established in the Gulf of Mexico. It’s an investigation of reports involving animals that witnesses believed were something that shouldn’t be there.
And this investigation isn’t over.
There are additional reports and possible explanations I intend to examine in future installments.
Because sometimes the most interesting outdoor mysteries aren’t about proving something extraordinary.
They’re about figuring out what somebody actually saw.

There was a time when a strange photograph could start an investigation. Today, it might have been generated 30 seconds ago.
Artificial intelligence has changed the game when it comes to wildlife imagery. We now live in a world where someone can create a convincing photograph or video of virtually any animal imaginable and put it in front of thousands (or millions) of people before anyone stops to ask whether it is real. For cryptozoology, that presents an enormous problem.
Cryptozoology has never enjoyed widespread acceptance within mainstream wildlife science. At its best, however, it involves something I understand very well as a wildlife journalist: collecting reports, interviewing eyewitnesses, researching historical records, examining photographs and video and going into the field to see what can actually be documented.
That doesn’t mean every report is true. Far from it. But investigation is supposed to be about separating what can be demonstrated from what cannot, and right now that process is getting harder.
When Everything Looks Real
I’ve spent years looking into unusual wildlife reports. Some turn out to have perfectly reasonable explanations. Others involve misidentification, and some are obvious nonsense. Occasionally, however, you encounter something that leaves legitimate questions.
The problem today is that those categories are becoming increasingly difficult for the average person scrolling through social media to distinguish. AI-generated wildlife images have become astonishingly convincing. Videos can be manipulated, old photographs can be given completely new stories and real wildlife footage can be removed from its original context and presented as something it isn’t.
Then the algorithms take over, and the most sensational version frequently travels farther than the correction. That doesn’t just hurt cryptozoology. It damages public understanding of wildlife in general.
The Credibility Problem
There is another problem that technology cannot be blamed for: standards matter.
If every strange sound in the woods becomes evidence of an unknown creature, eventually none of it means anything. If every blurry photograph is presented as proof before obvious explanations are investigated, credibility disappears. The same applies to eyewitness accounts.
I believe eyewitnesses should be treated respectfully. I’ve interviewed enough people over the years to know that sincere people can report extraordinary things, but sincerity is not the same thing as proof. That’s where investigation comes in.
Can the location be verified? Does the description match known wildlife? Were there tracks, photographs or other witnesses? Does the timeline hold together? Is there a reasonable conventional explanation? Those aren’t questions designed to destroy a mystery. They’re the questions that make investigating one worthwhile.
But It Cuts Both Ways
There is another side of this conversation that deserves attention. Skepticism is healthy and, in fact, essential. But skepticism has to operate by the same rules.
If extraordinary claims require evidence, claims supposedly disproving extraordinary things should be examined carefully, too. A confident conclusion isn’t automatically a scientific one simply because it supports the conventional explanation.
That issue is about to become particularly interesting. A forthcoming film dealing with this world is already raising questions that I believe deserve examination—not because I have any interest in blindly defending cryptozoology, but because evidence and methodology should matter regardless of which conclusion someone wants to reach.
I’ll have more to say about that. For now, I’m asking a different question: Has AI, social media sensationalism and declining standards of evidence brought us to the death of cryptozoology, or has it simply made genuine investigation more important than ever?
That’s the subject of the latest episode of Dark Outdoors.
Because the outdoors has a dark side.

The 725.8-pound feral hog taken in Southeast Texas has generated a tremendous amount of attention since I first reported on it.
Its incredible size immediately got people’s attention, but then viewers started focusing on something else. The massive animal was black and white, and some questioned whether a hog that looked like this and weighed more than 700 pounds could really be feral.
It was.
This was a free-ranging feral hog, and its weight wasn’t someone’s field estimate. The animal was photographed on a scale registering 725.8 pounds.
But the debate made me connect some dots I hadn’t connected before.
For years, I’ve known about giant domestic hogs being released at different locations in this region. That information takes on a new dimension when you consider an animal like this one and the tremendous variation found among feral hogs.
My new video looks at that history, what actually makes a hog feral and how past releases could potentially help explain some of the enormous and unusual-looking feral hogs roaming Southeast Texas.
WATCH THE NEW VIDEO
There are some important distinctions here.
A feral hog doesn’t have to look like the stereotypical lean, black, long-snouted hog many people picture when they hear the word “feral.” Domestic swine can escape or be released and become feral. Their descendants can also reproduce with other free-ranging hogs, contributing to the tremendous variation in size, coloration and physical characteristics found in feral hog populations.
In other words, domestic characteristics don’t automatically make a free-ranging hog somebody’s pet or a barnyard animal.
And that’s where this story gets much more interesting.
I’ve known for years about giant domestic hogs being released at different locations in this region over a long period of time. I knew about these releases long before this 725.8-pound hog appeared.
What I hadn’t done was connect that history with the larger story of giant feral hogs in Southeast Texas.
I’m not claiming this particular hog came from one of those releases because I don’t have evidence connecting this individual animal to a specific release. What we don’t know is the complete ancestry of this hog.
But that doesn’t change what it was when it was killed.
It was a free-ranging feral hog.
The more intriguing question is whether the history of giant domestic hog releases could help explain some of the extraordinary size, coloration and other characteristics occasionally seen in feral hogs in this region.
Could some of those genetics still be represented in hogs roaming Southeast Texas today?
That’s a question worth investigating, and it’s a much bigger story than simply arguing over what the word “feral” means.
The 725.8-pound weight is documented. The animal was free-ranging. The history of giant domestic hog releases in the region is real.
What we don’t know is exactly how all those pieces fit together.
But I’ve connected enough of the dots to know there’s more to investigate.
And I don’t think we’re finished with the giant hog story yet.
Because the outdoors has a dark side.

A pair of eyes emerged from the bushes in the darkness. There had recently been a mountain lion sighting in the area, so I raised my rifle and looked through the scope. What I saw wasn’t a mountain lion. It looked like a red wolf.
I lowered the rifle.
That encounter has stayed with me for years, and it opens a new episode of Dark Outdoors®, “The Night I Had a Red Wolf in My Crosshairs.” The episode explores that experience, other strange wild canine encounters and the fascinating story of an animal that once roamed Texas and Louisiana but came perilously close to disappearing forever.
There is another fascinating chapter to this story.
Researchers studying wild canines along the Texas Gulf Coast have discovered animals carrying significant amounts of red wolf ancestry. That raises intriguing questions about whether genetic remnants of the wolves that once inhabited this region have survived within coastal coyote populations.
I explored that story in a video examining Texas coyotes, red wolf genetics and the remarkable possibilities scientists are considering for conserving those genes.
The red wolf (Canis rufus) is one of North America’s great wildlife conservation stories.
Red wolves once occupied portions of the eastern and south-central United States, including Texas and Louisiana. By the 20th century, persecution, habitat changes and hybridization with coyotes helped push them toward extinction in the wild.
A small number of animals were captured along the Texas-Louisiana Gulf Coast to establish a captive breeding program. Those animals became the foundation for an effort that prevented the red wolf from disappearing completely.
Today, the only recognized wild population exists in eastern North Carolina.
That makes the discovery of red wolf ancestry in Gulf Coast canines especially fascinating. The wolves themselves may have disappeared from Texas, but some of their genetics apparently did not.
What Was in My Crosshairs?
I’m not claiming that the animal I encountered that night was a genetically pure red wolf.
There was no DNA test. I didn’t capture it. I didn’t have a biologist standing beside me.
I can only tell you what happened.
I saw those eyes emerge from the bushes. With a mountain lion recently reported in the area, I raised my rifle. When I got a better look at the animal, what I saw looked like a red wolf.
So I lowered the gun.
Years later, as research began revealing the surprising amount of red wolf ancestry surviving in some Gulf Coast coyotes, encounters like mine became even more interesting.
Could I have encountered an animal carrying substantial red wolf genetics?
I don’t know.
But unlike a lot of mysterious wildlife stories, we now know there really are wild canines along the Texas Gulf Coast carrying genetic echoes of the red wolf.
And that makes this story worth another look.
Hear the Full Story
In the complete Dark Outdoors episode, I tell the story of that night and explore other unusual encounters I’ve had with wild canines over the years.
Listen to “The Night I Had a Red Wolf in My Crosshairs”:
A man walked outside his Texas home and discovered a huge cat inside his chicken coop. It wasn’t a bobcat, and it didn’t look like a mountain lion. The animal he described looked like an African lion.
That encounter is at the center of a new episode of Dark Outdoors®, examining one of the strangest categories of wildlife reports I have investigated over the years: big cats that don’t seem to belong where people are seeing them.
For decades, I have investigated reports of unusual cats in Texas and across the South. Mountain lions are responsible for some of them. Bobcats, especially when seen briefly or under unusual conditions, can account for others. Misidentification is a legitimate part of investigating any unusual wildlife report, and it should always be considered before looking for a more exotic explanation.
But occasionally a report comes along that doesn’t fit comfortably into those categories. The chicken-coop encounter is one of them. The witness described an animal that appeared to be an African lion. That’s an extraordinary claim, and without photographs, DNA or other physical evidence, there is no way to prove exactly what stood inside that coop.
The possibility of an exotic cat appearing in Texas, however, isn’t as impossible as it might initially sound. Texas has a long history of privately held exotic wildlife. Animals escape, and historically some have been deliberately released. In some cases, an exotic animal could potentially survive unnoticed for a period of time, particularly in remote country with abundant cover and prey.
That doesn’t mean every report of an unusual cat is an escaped exotic. It simply means the possibility shouldn’t automatically be dismissed when examining a credible report.
The Giant Tracks
The lion report isn’t the only strange big-cat case I discuss in this episode. I also recount one of my own investigations involving enormous cat tracks that immediately caught my attention because of their size.
Photo by Chester Moore
I’ve spent much of my life around wildlife and studying animal sign, and these tracks appeared far larger than what I expected to find from a native cat in that area. That doesn’t automatically make them evidence of some exotic predator. Tracks can be deceptive. Mud can distort a print, a paw can slip and multiple impressions can overlap.
Those possibilities always have to be considered, but when unusually large tracks begin showing up in the same broader conversation as reports of unusually large cats, the subject becomes much more interesting.
Could Exotic Cats Be Roaming Texas?
Texas is enormous, with millions of acres of forests, swamps, brush country, ranchland and river bottoms where an animal can remain surprisingly difficult to detect. Mountain lions themselves demonstrate how effectively a large predator can move primarily at night, avoid people and cover tremendous distances without being seen by most of the people living around it.
Now consider an escaped exotic cat behaving in much the same way. Could a lion, leopard or another large captive cat survive for some period of time in the wild? Under the right circumstances, it’s certainly possible. The much harder question is whether that possibility explains any particular sighting.
That’s where evidence matters. A witness report can begin an investigation, but tracks, photographs, video, hair, scat or DNA can move a case into an entirely different category.
But unfortunately A.I. has changed this to a large extent because it’s very difficult to believe any photo or video evidence.
The Mystery Cats of the South
Stories of strange cats have circulated through Texas, Louisiana and other parts of the South for generations. Some witnesses report oversized mountain lions. Others describe black cats they call panthers. Still others report animals whose size, coloration or physical appearance doesn’t seem to match any native species.
There is a temptation to put every one of those reports into the same box, but I don’t think that’s useful. Some are undoubtedly misidentifications. Some may involve actual mountain lions appearing in places where people aren’t accustomed to seeing them. Other reports simply don’t contain enough information to reach any conclusion.
Then there are the cases that remain difficult to explain. Those are the ones that have kept me interested in this subject for decades.
Something That Isn’t Supposed to Be There
The goal isn’t to turn every strange animal sighting into a monster story. It’s to investigate what people report and ask the right questions. What did the witness actually see? Does the description match known wildlife? Could an exotic animal have escaped in the area? Are there tracks, photographs, hair, scat or other physical evidence? Have independent witnesses reported something similar?
Those questions are far more interesting than simply declaring every unusual sighting impossible or, on the other extreme, believing every extraordinary claim without evidence. Most wildlife mysteries probably have ordinary explanations.
But every once in a while, somebody walks outside, looks into a chicken coop and sees something that isn’t supposed to be there.
That’s when things get interesting.

Deep along the Brazos River, something attacked a calf in the darkness.
The people nearby couldn’t clearly see what was happening.
But they could hear it.
They described multiple animals involved in the attack and, most disturbingly, what sounded like bones breaking as the calf was seemingly pulled apart with astonishing speed.
What happened that night?
I don’t know—and I’m not going to pretend that I do.
In the new Dark Outdoors® episode, “They Could Hear Them Tearing the Calf Apart,” you can hear the account directly from one of the people who was there. The earwitness tells his own story, describing what he heard along the Brazos River that night and why the experience has stayed with him.
The Brazos River runs through some wild Texas country, and there are certainly predators capable of attacking young livestock.
Coyotes immediately come to mind, particularly when multiple animals are described. Bobcats occur throughout Texas, mountain lions are present in parts of the state and feral hogs can attack vulnerable animals and readily scavenge carcasses.
But identifying what could kill something is very different from determining what did.
That’s important here. This was an event experienced primarily through sound, in darkness, during what was apparently a violent and chaotic attack.
We make no assumptions about what was responsible.
What makes the story compelling is the extraordinary nature of what the earwitness describes hearing and how quickly the attack seemed to unfold. In the podcast, you aren’t simply hearing my interpretation of his story. You hear him describe the encounter in his own words.
Strange Things Happen in Predator Country
I’ve spent decades observing wildlife, and I’ve encountered strange examples of predation myself.
Sometimes you find evidence that seems straightforward. Other times you look at tracks, wounds, feeding patterns or the condition of an animal and something doesn’t fit what you expected.
That doesn’t mean a monster did it.
It means you don’t know.
Wild animals don’t always behave according to the simplified descriptions we give them. Predators exploit unusual opportunities, multiple species may visit the same carcass and scavengers can dramatically change a scene after an animal dies.
I’ve seen strange predation in the wild where I couldn’t confidently explain exactly what happened. Experiences like those are one reason I take accounts like this seriously without making extraordinary claims about them.
Hearing Can Be Worse Than Seeing
Anyone who has spent significant time outdoors after dark knows how powerful sound becomes when you can’t see its source. Your mind tries to construct an image from what your ears are telling you.
Now imagine hearing an animal fighting for its life somewhere beyond your ability to see clearly.
Nature isn’t a horror movie. Predators aren’t evil. They kill because that’s how they survive, and predator-prey relationships are fundamental to the natural world.
But that doesn’t make hearing a violent kill in the darkness any less unsettling.
In the full episode, the Brazos River earwitness describes exactly what he remembers hearing. I also examine some of the possibilities and share other unusual predator-prey observations that have left me with questions of my own.
We make no assumptions about what happened along the Brazos River that night. We simply present the account, consider what we know about predators and let the person who experienced it tell you what he heard.
Sometimes there isn’t enough evidence to explain everything that happens in the wild.
And sometimes hearing it is worse than seeing it.
Because the outdoors has a dark side.

Reports of black panthers have circulated through Texas for generations. From the Pineywoods to South Texas, people have described large, long-tailed black cats crossing roads, slipping through creek bottoms and appearing in places where conventional wildlife wisdom says they shouldn’t exist.
Most of these encounters leave little behind beyond a story. But occasionally a report comes from an experienced outdoorsman who gets a good enough look at the animal to make the account difficult to casually dismiss. My friend David Cleaver had one of those encounters, and what he describes sounds remarkably like one of the most impressive cats on Earth—a black jaguar.
Hear David’s complete firsthand account on the new Dark Outdoors® episode “Black Ghost: A Texas Jaguar Encounter” on Apple Podcasts or Spotify.
David is a dedicated outdoorsman and hiker, and I consider him a highly reliable witness. His encounter wasn’t simply a fleeting glimpse of something dark disappearing into the brush. He describes a large black feline whose size, build and overall appearance didn’t match the animals normally encountered in Texas.
The possibility of a jaguar deserves consideration because jaguars aren’t strangers to Texas. They are part of our natural history and once occurred in the state. Texas Parks and Wildlife Department information lists the jaguar as endangered and considers it possibly extirpated in Texas, while acknowledging the possibility of a rare wandering animal arriving from Mexico.
That is a long way from saying jaguars are secretly breeding somewhere in Texas. There is no evidence of that. But an individual jaguar wandering into the state is biologically possible, and jaguars have continued to appear north of Mexico in the American Southwest.
But What About a Black Jaguar?
This is where David’s encounter becomes especially mysterious.
Black jaguars are real. Melanism can produce jaguars that appear almost completely black, although their characteristic rosette pattern can often still be seen under the right lighting.
There is a significant problem, however, with putting one in Texas. The U.S. Fish and Wildlife Service reports that melanistic jaguars have never been documented north of Mexico’s Isthmus of Tehuantepec. A black jaguar appearing in Texas would therefore be an extraordinary occurrence requiring extraordinary evidence.
So what are people seeing when they report black panthers in Texas?
There probably isn’t a single answer. Some sightings undoubtedly involve domestic cats, dogs, otters or other animals seen under poor conditions. Mountain lions can also appear extremely dark in certain light, although there is no scientifically documented population of truly black mountain lions.
But that doesn’t mean every report should automatically be discarded.
I’ve investigated unusual wildlife reports for years, and I’ve learned that the important questions are often simple ones: Who saw the animal? How close were they? How long did they see it? What characteristics could they clearly identify? And how experienced is the witness with wildlife?
David Cleaver’s encounter deserves to be considered in that light.
I can’t tell you that David saw a black jaguar. There is no photograph, DNA or other physical evidence that could prove what the animal was. But knowing David and hearing the details of his encounter, I believe he saw something extraordinary.
And considering that jaguars once roamed Texas, the possibility of an occasional big cat appearing where we least expect it is a mystery worth investigating.
I can’t tell you that David saw a black jaguar. There is no photograph, DNA or other physical evidence that could prove what the animal was. But knowing David and hearing the details of his encounter, I believe he saw something extraordinary.
Jaguars once roamed Texas. Whether one of their darkest forms could ever return is another question entirely.
For now, the black ghost remains just that—a mystery.

Every Shark Week, one question seems to rise to the surface almost as predictably as the television specials themselves:
Could the megalodon still be alive?
It’s a fascinating question, and one I’ve been asked countless times over the years.
Let me answer it right away.
Personally, I don’t believe megalodon is still swimming our oceans. The scientific evidence strongly supports the conclusion that this prehistoric giant disappeared a long time ago.
Illustration by Bill Rebsamen.
But that doesn’t mean the mystery ends there.
For more than a century, experienced fishermen, sailors, explorers, and divers have reported seeing sharks so enormous they seemed almost beyond belief. These weren’t always sensationalists looking for attention. Many were seasoned outdoorsmen and mariners who knew the sea as well as anyone.
If they weren’t seeing a living megalodon…
What were they seeing?
That’s the question I investigate in the latest episode of my Dark Outdoors® podcast.

Rather than trying to prove the impossible, this episode takes an investigative look at some of the world’s most famous giant shark reports and compares them with what we know through modern marine science. Along the way, we separate documented history from maritime folklore while exploring why stories of enormous sharks continue to capture our imagination.
Among the accounts examined is legendary outdoorsman and author Zane Grey’s remarkable shark encounter in the South Pacific, mysterious reports of giant sharks from Australian waters, and the enduring legend of Baja California’s so-called “Black Demon.” These stories have become part of maritime history, but they also raise legitimate questions about how eyewitnesses perceive extraordinary events on the open ocean.
The episode also explores something equally fascinating—the remarkable reality of sharks that actually exist.
Great white sharks can reach astonishing proportions. Legendary charter captain Frank Mundus became famous for catching some of the largest great whites ever documented, helping shape public perception of these incredible predators. More recently, Deep Blue, believed to be among the largest reliably documented great white sharks ever recorded, reminded the world just how immense these animals can become.
We also examine whale sharks, basking sharks, and the megamouth shark—species whose sheer size can leave even experienced observers stunned under the right conditions.
Having spent years researching great white sharks, interviewing leading shark scientists, documenting Gulf records, and diving with these magnificent predators, I’ve learned something important.
Reality is often every bit as fascinating as legend.
Sometimes more so.
One of the goals of Dark Outdoors has always been to investigate mysteries without abandoning science. It’s possible to appreciate compelling eyewitness accounts while also recognizing that extraordinary claims require extraordinary evidence. That’s especially true when discussing an animal as iconic as the megalodon.
This episode doesn’t argue that megalodon somehow escaped extinction.
Instead, it explores why reports of giant sharks continue to emerge from around the world and examines the very real animals that may explain at least some of those extraordinary encounters.
Whether you’re fascinated by sharks, cryptozoology, maritime history, or simply enjoy thoughtful investigations into the unexplained, I think you’ll find this episode an entertaining journey into one of the ocean’s greatest legends.
As Shark Week approaches to shine a spotlight on sharks from around the globe, it’s a perfect time to remember that while the megalodon almost certainly belongs to the distant past, our oceans are still home to giants capable of inspiring wonder, respect, and perhaps just a little bit of mystery.
