Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week we’re going to look at some huge, weird sharks, but they’re not what you may expect when you hear the word shark. Welcome to the strange world of giant filter feeders!

This episode is inspired by an article in the brand new issue of Science, which you may have heard about online. A new species of shark is described in that issue, called the eagle shark because of the shape of its pectoral fins. They’re long and slender like wings.

The fossil was discovered in 2012 in northeastern Mexico, but not by paleontologists. It came to light in a limestone quarry, where apparently a quarry worker found it. What happened to it at that point isn’t clear, but it was put up for sale. The problem is that Mexico naturally wants fossils found in Mexico to stay in Mexico, and the authors of the study are not Mexican. One of the authors has a history of shady dealings with fossil smugglers too. On the other hand, the fossil has made its way back to Mexico at last and will soon be on display at a new museum in Nuevo León.

Fossils from this quarry are often extremely well preserved, and the eagle shark is no exception. Sharks don’t fossilize well since a shark’s skeleton is made of cartilage except for its teeth, but not only is the eagle shark’s skeleton well preserved, we even have an impression of its soft tissue.

The eagle shark was just slightly shorter than 5 ½ feet long, or 1.65 meters. Its tail looks like an ordinary shark tail but that’s the only ordinary thing about it. The head is short and wide, without the long snout that most sharks have, it doesn’t appear to have dorsal or pelvic fins, and its pectoral fins, as I mentioned a minute ago, are really long. How long? From the tip of one pectoral fin to the other measures 6.2 feet, or 1.9 meters. That’s longer than the whole body.

Researchers think the eagle shark was a filter feeder. Its mouth would have been wide to engulf more water, which it then filtered through gill rakers or some other structure that separated tiny animals from the water. It expelled the water through its gills and swallowed the food.

The eagle shark would have been a relatively slow swimmer. It glided through the water, possibly flapping its long fins slowly in a method called suspension feeding, sometimes called underwater flight. If this makes you think of manta rays, you are exactly correct. The eagle shark occupied the same ecological niche that manta rays do today, and the similarities in body form are due to convergent evolution. Rays and sharks are closely related, but the eagle shark and the manta ray evolved suspension feeding separately. In fact, the eagle shark lived 93 million years ago, 30 million years before the first manta remains appear in the fossil record.

The eagle shark lived in the Western Interior Seaway, a shallow sea that stretched from what is now the Gulf of Mexico straight up through the middle of North America. Because it’s the only specimen found so far, we don’t know when it went extinct, but researchers suspect it died out 65 million years ago at the same time as the non-avian dinosaurs. We also don’t have any preserved teeth, which makes it hard to determine what sharks it was most closely related to. Hopefully more specimens will turn up soon.

Now that we’ve mentioned the manta ray, let’s talk about it briefly even though it’s not a shark. It is big, though, and it’s a filter feeder. If you’ve never seen one before, they’re hard to describe. If it had gone extinct before humans started looking at fossils scientifically, we’d be as astounded by it as we are about the eagle shark—maybe even moreso because it’s so much bigger. Its body is sort of diamond-shaped, with a blunt head and short tail, but elongated fins that are broad at the base but end in drawn-out points.

Manta rays are measured in width, sometimes called a wingspan since their long fins resemble wings that allow it to fly underwater. There are two species of manta ray, and even the smaller one has a wingspan of 18 feet, or 5.5 meters. The larger species can grow 23 feet across, or 7 meters. Some other rays are filter feeders too, all of them closely related to the manta.

The manta ray lives in warm oceans, where it eats zooplankton. Its mouth is wide and when it’s feeding it moves forward with its mouth open, letting water flow into the mouth and through the gills. Gill rakers collect tiny food, which the manta ray swallows. It has a pair of fins on either side of the mouth that are sometimes called horns, but which are properly called cephalic fins. Cephalic just means “on the head.” These fins help direct water into the mouth. When a manta ray isn’t feeding, it closes its mouth just like any other shark, folding its shallow jaw shut. For years I thought it closed its mouth by folding the cephalic fins over it, but that’s not the case, although it does roll the fins up into little points. The manta ray is mostly black with a white belly, but some individuals have white markings on the back and black speckles and splotches underneath. We talked about some mysteries associated with its coloring in episode 96.

The eagle shark isn’t the only filter feeding shark. The earliest known is Pseudomegachasma, the false megamouth, which lived around 100 million years ago. It was only described in 2015 after some tiny shark teeth were found in Russia. The teeth looked like those of the modern megamouth shark, although they’re probably not related. The teeth are only a few millimeters long but that’s the same size as teeth from the megamouth shark, and the megamouth grows 18 feet long, or 5.5 m.

Despite its size, the megamouth shark wasn’t discovered until 1976, and it was only found by complete chance. On November 15 of that year, a U.S. Navy research ship off the coast of Hawaii pulled up its sea anchors. Sea anchors aren’t like the anchors you may be thinking of, the big metal ones that drop to the ocean’s bottom to keep a ship stationary. A sea anchor is more like an underwater parachute for ships. It’s attached to the ship with a long rope on one end, and opens up just like a parachute underwater. The tip of the parachute has another rope attached with a float on top. When the navy ship brought up its sea anchors, an unlucky shark was tangled up in one of them. The shark was over 14 ½ feet long, or 4 ½ m, and didn’t look like any shark anyone had ever seen.

The shark was hauled on board and the navy consulted marine biologists around the country. No one knew what the shark was. It wasn’t just new to science, it was radically different from all other sharks known. Since then, only about 100 megamouth sharks have ever been sighted, so very little is known about it even now.

The megamouth is dark brown in color with a white belly, a wide head and body, and a large, wide mouth. The inside of its lower lip is a pale silvery color that reflects light, although researchers aren’t sure if it acts as a lure for the tiny plankton it eats, or if it’s a way for megamouths to identify each other. It’s sluggish and spends most of its time in deep water, although it comes closer to the surface at night.

The basking shark is even bigger than the megamouth. It can grow up to 36 feet long, or 11 meters. It’s so big it’s sometimes mistaken for the great white shark, but it has a humongous wide mouth and unusually long gill slits, and, of course, its teeth are teensy. It’s usually dark brown or black, white underneath, and while it spends a lot of its time feeding at the surface of the ocean, in cold weather it spends most of its time in deep water. In summer, basking sharks gather in small groups to breed, and sometimes will engage in slow, ponderous courtship dances that involve swimming in circles nose to tail.

But the biggest filter feeder shark alive today, and possibly alive ever, is the whale shark. It gets its name because it is literally as large as some whales. It can grow up to 62 feet long, or 18.8 meters, and potentially longer.

The whale shark is remarkably pretty. It’s dark gray with a white belly, and its body is covered with little white or pale gray spots that look like stars on a night sky. Its mouth is extremely large and wide, and its small eyes are low on the head and point downward. Not only can it retract its eyeballs into their sockets, the eyeballs actually have little armored denticles to protect them from damage. The body also has denticles, plus the whale shark’s skin is six inches thick, or 15 cm.

The whale shark lives in warm water and migrates long distances. It mostly feeds near the surface although it sometimes dives deeply to find plankton. It filters water differently from the megamouth and basking sharks, which use gill rakers. The whale shark has sieve-like filter pads instead. The whale shark doesn’t need to move to feed, either. It can gulp water into its mouth by opening and closing its jaws, unlike the other living filter feeders we’ve talked about so far.

We talked about the whale shark a lot in episode 87, if you want to know more about it.

All these sharks are completely harmless to humans, but unfortunately humans are dangerous to the sharks. Even though they’re all protected, they’re vulnerable to getting tangled in nets, killed by ships running over them, and killed by poachers.

One interesting thing about these three massive filter feeding sharks is their teeth. They all have tiny teeth, but the mystery is why they have teeth at all. Their teeth aren’t just tiny, they have a LOT of teeth, more than ordinary sharks do. It’s the same for the filter feeding rays. They have hundreds of teensy teeth that the animals don’t use for anything, as far as researchers can tell. One theory is that the babies may use their teeth before they’re born. All of the living filter feeders we’ve talked about, including manta rays, give birth to live pups instead of laying eggs. The eggs are retained in the mother’s body while they grow, and she can have numerous babies growing at different stages of development at the same time. The babies have to eat something while they’re developing, once the yolk in the egg is depleted, and unlike mammals, fish don’t nourish their babies through umbilical cords. Some researchers think the growing sharks eat the mother’s unfertilized eggs, and to do that they need teeth to grab hold of slippery eggs. That still doesn’t explain why adults retain the teeth and even replace them throughout their lives just like other sharks. Since all of the filter feeders have teeth although they’re not related, the teeth must confer some benefit.

So, why are these filter feeders so enormous? Many baleen whales are enormous too, and baleen whales are also filter feeders. Naturally, filter feeders need large mouths so they can take in more water and filter more food out of it. As a species evolves a larger mouth, it also evolves a larger body, and this has some useful side effects. A large animal retains heat even if it’s not actually warm-blooded. A giant fish can live comfortably in cold water as a result. Filter feeding also requires much less effort than chasing other animals, so a giant filter feeder has plenty of energy for a relatively low intake of food. And, of course, the larger an animal is, the fewer predators it has because there aren’t all that many giant predators. At a certain point, an adult giant animal literally has no predators. Nothing attacks an adult blue whale, not even the biggest shark living today. Even a really big great white shark isn’t going to bite a blue whale. The blue whale would just bump the shark out of the way and probably go, “HEY, STOP IT, THAT TICKLES.” The exception, of course, is humans, who used to kill blue whales, but you know what I mean.

Let’s finish with a filter feeder that isn’t a shark. It’s not even closely related to sharks. It’s a ray-finned fish that lived around 165 million years ago, Leedsichthys problematicus. Despite not being related to sharks and being a member of what are called bony fish, its skeleton is partially made of cartilage, so fossilized specimens are incomplete, which is why it was named problematicus. Because the fragmented fossils are a problem. I’m genuinely not making this up to crack a dad joke, that’s exactly why it got its name. One specimen is made up of 1,133 pieces, disarticulated. That means the pieces are all jumbled up. Worst puzzle ever. Remains of Leedsichthys have been found in Europe and South America.

As a result, we’re not completely sure how big Leedsichthys was. The most widely accepted length is 50 feet long, or 16 meters. If that’s anywhere near correct, it would make it the largest ray-finned fish that ever lived, as far as we know. It might have been much larger than that, though, possibly as long as 65 feet, or 20 meters.

Leedsichthys had a big head with a mouth that could open extremely wide, which shouldn’t surprise you. Its gills had gill rakers that it used to filter plankton from the water. And we’re coming back around to where we started, because like the eagle shark, Leedsichthys had long, narrow pectoral fins. Some palaeontologists think it had a pair of smaller pelvic fins right behind the pectoral fins instead of near the tail, but other palaeontologists think it had no pelvic fins at all. Because we don’t have a complete specimen, there’s still a lot we don’t know about Leedsichthys.

The first Leedsichthys specimen was found in 1886 in a loam pit in England, by a man whose last name was Leeds, if you’re wondering where that part of the name came from. A geologist examined the remains and concluded that they were part of (wait for it) a type of stegosaur called Omosaurus. Two years later the famous early palaeontologist Othniel Marsh examined the fossils, probably rolled his eyes, and identified them as parts of a really big fish skull.

In 1899, more fossils turned up in the same loam pits and were bought by the University of Cambridge. IA palaeontologist examined them and determined that they were (wait for it) the tail spikes of Omosaurus. Leeds pointed out that nope, they were dorsal fin rays of a giant fish, which by that time had been named Leedsichthys problematicus.

In 1982, some amateur palaeontologists excavated some fossils in Germany, but they were also initially identified as a type of stegosaur—not Omosaurus this time, though. Lexovisaurus. I guess this particular giant fish really has been a giant problem.

Yes, they smell. They smell so bad.

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

It’s October, and you know what that means! Monsters! …and have I got a creepy monster for you this week. Grab your Halloween candy and a flashlight while I tell you about something called a globster.

If you live near the seashore, or really if you’ve spent any time at all on the beach, you’ll know that stuff washes ashore all the time. You know, normal stuff like jellyfish that can sting you even though they’re dead, pieces of debris that look an awful lot like they’re from shipwrecks, and the occasional solitary shoe with a skeleton foot inside. But sometimes things wash ashore that are definitely weird. Things like globsters.

A globster is the term for a decayed animal carcass that can’t be identified without special study. Globsters often look like big hairy blobs, and are usually white or pale gray or pink in color. Some don’t have bones, but some do. Some still have flippers or other features, although they’re usually so decayed that it’s hard to tell what they really are. And they’re often really big.

Let’s start with three accounts of some of the most famous globsters, and then we’ll discuss what globsters might be and why they look the way they do.

The St. Augustine monster was found by two boys bicycling on Anastasia Island off the coast of Florida in November 1896. It was partially buried in sand, but after the boys reported their finding, people who came to examine it eventually dug the sand away from the carcass. It was 21 feet long, or almost 6.5 meters, 7 feet wide, or just over 2 meters, and at its tallest point, was 6 feet tall, or 1.8 meters. Basically, though, it was just a huge pale pink lump with stumpy protrusions along the sides.

A local doctor, DeWitt Webb, was one of the first people to examine the carcass. He thought it might be the rotten remains of a gigantic octopus and described the flesh as being rubbery and very difficult to cut. Another witness said that pieces of what he took to be parts of the tentacles were also strewn along the beach, separated from the carcass itself.

Dr. Webb sent photographs and notes to a cephalopod expert at Yale, Addison Verrill. He at first thought it might be a squid, but later changed his mind and decided it must be an octopus of enormous proportions—with arms up to 100 feet in length, or over 30 meters.

In January a storm washed the carcass out to sea, but the next tide pushed it back to shore two miles away. Webb sent samples to Verrill, who examined them and decided it was more likely the remains of a sperm whale than a cephalopod.

In 1924, off the coast of South Africa, witnesses saw a couple of orcas apparently fighting a huge white monster covered with long hair—far bigger than a polar bear. It had an appendage on the front that looked like a short elephant trunk. Witnesses said the animal slapped at the orcas with its tail and sometimes reared up out of the water. This went on for three hours.

The battle was evidently too much for the monster, and its corpse washed ashore the next day. It measured 47 feet long in all, or 14.3 meters, and the body was five feet high at its thickest, or 1.5 meters. Its tail was ten feet long, or over three meters, and its trunk was five feet long and over a foot thick, or about 35 cm. It had no legs or flippers. But the oddest thing was that it didn’t seem to have a head either, and there was no blood on the fur or signs of fresh wounds on the carcass.

The carcass was so heavy that a team of 32 oxen couldn’t move it. The reason someone tried to move it was because it stank, and the longer it lay on the beach the more it smelled.

Despite its extraordinary appearance, no scientists came to investigate. After ten days, the tide carried it back out to sea and no one saw it again. Zoologist Karl Shuker has dubbed it Trunko and has written about it in several of his books.

Another globster was discovered well above ordinary high tide on a Tasmanian beach in 1960 after a massive storm. It was 20 feet long, or 6 meters, 18 feet wide, or 5.5 meters, and about 4 ½ feet high at its thickest, or 1.4 meters. It stayed on the beach for at least two years without anyone being especially interested in it. It was in a fairly remote area, admittedly. It wasn’t until 1962 that a team of zoologists examined it. They reported that it was ivory-colored, incredibly tough, boneless, and without any visible eyes. The lump had four large lobes, but it also appeared to have gill slits. One of the zoologists suggested it might be an enormous stingray.

So what were these three globsters?

Let’s look at Trunko first. Shuker points out that when a shark decomposes, it can take on a hairy appearance due to exposed connective tissue fibers. But Trunko was fighting two orcas only hours before it washed ashore.

OR WAS IT??

Here’s the thing. No one saw the fight from up close and orcas are well known to play with their food. There’s a very good chance that Trunko was already long dead and that the orcas came across it and batted it around in a monstrous game of water volleyball. That would also explain why there was no blood associated with the corpse.

In that case, was Trunko a dead shark? At nearly 50 feet long, it would have had to be the biggest shark alive…and as it happens, there is a shark that can reach that length. It’s called the whale shark, which tops out at around 46 feet, or 14 meters, although we do have unverified reports of individuals nearly 60 feet long, or 18 meters—or even longer.

Like the megamouth shark, the whale shark is a filter feeder and its mouth is enormous, some five feet wide, or 1.5 meters. But the interior of its throat is barely big enough to swallow a fish. Its teeth are tiny and useless. Instead, it has sieve-like filter pads that it uses to filter tiny plants and animals from the water, including krill, fish eggs and larvae, small fish, and copepods. The filter pads are black and are probably modified gill rakers. The whale shark either gulps in water or swims forward with its mouth open, and water flows over the filter pads before flowing out through the gills. Tiny animals are directed toward the throat so the shark can swallow them.

The whale shark is gray with light yellow or white spots and stripes, and three ridges along each side. Its sandpaper-like skin is up to four inches thick, or 10 cm. It has thick, rounded fins, especially its dorsal fin, and small eyes that point slightly downward. It usually stays near the surface but it can dive deeply too, and it’s a fast swimmer despite its size. Females give birth to live babies which are a couple of feet long at birth, or 60 cm. While no one has watched a whale shark give birth, researchers think a shark may be pregnant with hundreds of babies at a time, but they mature at different rates and only a few are born at once.

The whale shark isn’t dangerous to humans at all, but humans are dangerous to whale sharks. It’s a protected species, but poachers kill it for its fins, skin, and oil.

The whale shark usually lives in warm water, especially in the tropics, but occasionally one is spotted in cooler areas. They’re well known off the coast of South Africa. If the Trunko globster was a dead whale shark, the “trunk” was probably the tapered end of the tail, with the flukes torn or rotted off. Most likely the jaws had rotted off as well, leaving no sign that the animal had a head or even which end the head should be on.

But sharks aren’t the only big animals in the ocean, and the skin and blubber of a dead whale can also appear furry once it’s broken down sufficiently due to the collagen fibers within it. Collagen is a connective tissue and it’s incredibly tough. It can take years to decay. Tendons, ligaments, and cartilage are mostly collagen, as are bones and blubber.

While we don’t know what Trunko really was, many other globsters that have washed ashore in modern times have been DNA tested and found to be whales. In 1990 the Hebrides blob washed ashore in Scotland. It was 12 feet long, or 3.7 meters, and appeared furry, with a small head at one end and finlike shapes along its back. Despite its weird appearance, DNA analysis revealed it was a sperm whale, or at least part of one. Another sperm whale revealed by DNA testing was the Chilean blob, which washed ashore in Los Muermos, Chile in 2003. It was 39 feet long, or 12 meters.

As for the tissue samples of the St Augustine monster, they still exist, and they’ve been studied by a number of different people with conflicting results. In 1971, a cell biologist from the University of Florida reported that it might be from an octopus. Cryptozoologist Roy Mackal, who was also a biochemist, examined the samples in 1986 and also thought the animal was probably an octopus. A more sophisticated 1995 analysis published in the Biological Bulletin reported that the samples were collagen from a warm-blooded vertebrate—in other words, probably a whale. The same biologist who led the 1995 analysis, Sidney Pierce, followed up in 2004 with DNA and electron microscope analyses of all the globster samples he could find. Almost all of them turned out to be remains of whale carcasses, of various different species. This included the Tasmanian globster.

Sometimes a globster is pretty obviously a whale, but one with a bizarre and unsettling appearance. The Glacier Island globster of 1930, for instance, was found floating in Eagle Bay in Alaska, surrounded by icebergs from the nearby Columbia Glacier. The head and tail were skeletal, but the rest of the body still had flesh on it, although it appeared to be covered with white fur. Its head was flattish and triangular and the tail was long. The men who found the carcass thought it had been frozen in the glacier’s ice.

They hacked the remaining flesh off to use as fishing bait, but they saved the skeleton. A small expedition of foresters came to examine the skeleton, which they measured at 24 feet and one inch, or over 7.3 meters. They identified it as a minke whale. The skeleton was eventually mounted and put on display in a traveling show, advertised as a prehistoric monster found frozen in a glacier. In 1931 the skeleton was donated to the National Museum of Natural History in Washington DC, where it remains in storage. Modern examinations confirm that it’s a minke whale.

On March 22, 2012, a rotting corpse 15 feet long, or 4.6 meters, with armor-like scutes along the length of its body, washed ashore on Folly Beach in South Carolina. This isn’t exactly a globster, since it was still fish-shaped, but I’m including it because I was literally at Folly Beach a matter of weeks after this thing washed ashore. I wish I’d seen it. It turned out that it wasn’t a sea monster as people assumed, but a rare Atlantic sturgeon.

Many globsters have stumps that look like the remains of flippers, legs, or tentacles. The Four Mile Globster that washed ashore on Four Mile Beach, Tasmania in 1998 had protrusions along its sides that looked like stumpy legs. It was 15 feet long, or 4.6 meters, and 6 feet wide, or 1.8 meters, with white hair and flippers that were separate from the protrusions. We don’t actually know for sure what this globster was.

In 1988 a treasure hunter found a globster now called the Bermuda blob. It was about eight feet long, or almost 2.5 meters, pale and hairy with what seemed to be five legs. The discoverer took samples of the massively tough hide, which were examined by Sidney Pierce in his team’s 1995 study of globster remains. This was one of the few that turned out to be from a shark instead of a whale, although we don’t know what species.

But sharks don’t have five legs. And the Four Mile Globster had six stumps that were separate from the flippers still visible on the carcass. So what causes these leg-like protrusions? They’re probably flesh and blubber stiffened inside with a bone or part of a bone, such as a rib. As the carcass is washed around by the ocean, the flesh tears in between the bones, making them look like stumps of appendages.

There’s a good reason why so many globsters turn out to be sperm whale carcasses. A sperm whale’s massive forehead is filled with waxy spermaceti oil. The upper portion of the head contains up to 500 gallons of oil in a cavity surrounded by tough collagen walls. Researchers hypothesize that this oil is used both for buoyancy and to increase the whale’s echolocation abilities. The lower portion of the forehead contains cartilage compartments filled with more oil, which may act as a shock absorber since males in particular ram each other when they fight. So much of the head of a sperm whale, which can be as big as 1/3 of the length of the whale, is basically a big mass of cartilage and connective tissue. After a whale dies, this buoyant section of the body can separate from the much heavier skeleton and float away on its own.

Globsters aren’t a modern phenomenon, either. We have written accounts of what were probably globsters dating back to the 16th century, and older oral traditions from folklore around the world. The main problem with globsters is that they’re not usually studied. They smell bad, they look gross, and they may not stay on the beach for long before the tide washes them back out to sea. For instance, after Hurricane Fran passed through North Carolina in 1996, a group of young men found a globster washed up on a beach on Cape Hatteras. They took pictures and estimated its length as twenty feet long, or six meters, six feet wide, or 1.8 meters, and four feet high at its thickest, or 1.2 meters. From the pictures it’s pretty disgusting, like a lump of meat with intestines or tentacles hanging from it. But the men weren’t supposed to be on the beach, which was part of the Cape Hatteras National Park and closed due to hurricane damage. They didn’t mention their find to anyone until the following year, when one of the men learned about the St Augustine Monster in his college biology class. By then, of course, the Cape Hatteras globster was long gone. While it might have been a rotting blob of whale blubber or a piece of dead shark, we don’t know for sure. So if you happen to find a globster on a beach, make sure to tell a biologist or park ranger so they can examine it…before it’s lost to science forever.
