- [Narrator] Behind
running, fishing is the most popular outdoor activity
for adults aged 25 and up. It's largely a totally innocent,
wacky-event-free venture, even being described as relaxing or fun. But all around the world, bizarre creatures are being reeled in, and it's doubtful that their captors would describe their catches
as normal or relaxing. Here are 10 mutant fish taking
over waters around the world. Number 10, cyclops shark. A bizarre discovery was
made in La Paz, Mexico, in the Sea of Cortez. A pregnant bull shark was
caught, and its fetuses removed. One of them was an albino with one eye. Pictures of the cyclops
shark were posted online, and some experts thought it was a hoax. Filipe Galvan, a well-respected
Mexican scientist, inspected the shark and
wrote a paper about it, which is under review. Lending further merit to the
authenticity of the incident, Tracy Ehrenberg, the general
manager of Pisces Sportfishing, conducted an interview with the fisherman who made the discovery. The man said that the pregnant shark was dead when they pulled it up, and that during the process
of filleting the shark they found ten fetuses. The other nine fetuses were fairly normal, both in color and the amount of eyes. And, although it's sad to think that someone still fishes for sharks, even though many species are endangered, and that they caught a pregnant one, this little albino cyclops
shark is almost cute enough to star in his own Disney adventures. Number nine, mutated two-headed dolphin. A two-headed, mutant dolphin washed up on the shore of Ismire on
the west coast of Turkey. It's believed to have only been around a year old when it died, as it was only a meter long. It was discovered by a schoolteacher, who watched in horror
as the mutant dolphin washed up on the shore. He then called the police, who took the dolphin's
body away for testing. Preliminary eyewitness reports said that the eyes and blow hole of one of the heads weren't open, which may mean that there were further deformations in the creature, other than the glaringly obvious one, which could have contributed to its death. No one knows whether this is a
rare case of conjoined twins, a natural type of deformation, or deformation caused by contaminants. Another incident of a
two-headed dolphin-like creature was reported in the Netherlands. They reported the first ever case of conjoined harbor porpoises. It was thrown back into the ocean because the fishermen
thought it might be illegal to have it in their possession and generally thought it was
a good idea not to risk it. They did take pictures before
throwing it back, however. There are a lot of things that indicate that the creature died
shortly after birth. It's tail had not stiffened, which is something that
porpoises need in order to swim, its dorsal fin had not
become vertical yet, and it still had hairs on its upper lip, which porpoises shed after birth. Conjoined twins are rare, even in humans. But they're even more rare in cetaceans, a group of animals that include porpoises, dolphins, whales, and
other similar creatures. In fact, the porpoise was only the 10th conjoined cetacean case at
the time of this writing. Many people have a soft spot
for dolphins and porpoises, so the thought of having two times the fun of a dolphin-like creature
in one animal is exciting. It's very unfortunate that this story turned out the way it did, instead of resulting in one
of the coolest animals ever. Number eight, pug nose striped bass. This mutation is fairly
common in striped bass. They're called pug-nosed
because the mutation causes them to have a large, lumpy head. One recent incident involves
one being caught in Maryland. The mutation doesn't affect
whether you can eat it or not, and doesn't have any
harmful effects on the fish, other than making it look really weird. Number seven, fish with horns. A fisherman in Siberia was stunned when he reeled in two pike that had horns on the tops of their heads. He referred to them as underwater dragons because of their appearance. The fish, which were identified as pike, had been pulled from the
River Irtysh in Russia. Locals blamed nuclear debris from Russian missile launch
experiments for the mutations. The fisherman dried and preserved the fish's heads and keeps them in his garage, which is probably a good thing because the last thing we need is horned, nuclear dragon fish swimming about. Number six, mutant fish in Russia. A gigantic fish had been
terrorizing locals in Siberia for months before it was finally caught. It had been attacking and trying to bite anyone who came near it. With a giant head, piranha-like teeth and a broad tail that resembled an oar, it's not surprising that
the locals were freaked out. However, It didn't turn
out to be a mutant. Experts say it was a wolffish, a type of endangered
bottom-feeding predator. But, with the amount of attacks, its appearance and just
the fact that a giant, massively aggressive fish was attacking anything that came near the water, it's really no surprise
that locals thought this was either some sort of
mutant or monster fish. Before I reveal the next example, you should subscribe if

County, North Carolina, are trying to figure out
what this huge fish is and where the video was taken. It was uploaded on Disclose
Screen's YouTube channel and simply said that the fish was from a lake in Gaston County,
but not which one. The fish appears to be
around four feet long and Disclose says it's around 30 lbs. Many are speculating that
it's some sort of carp, but they have no explanation for its fluorescent blue coloration. About one in a million
times a rainbow trout will be blue to due to
a rare genetic variant, but that occurs in approximately
one in a million cases. If this is what the fishermen saw here, they stumbled across an
extremely rare creature. Still, its a pretty large fish, and although its coloration
makes it appear to be some sort of wild Pokémon
that's appeared in the lake, it's most likely not. So, don't go wasting balls on it. Number four, Russian fish with two mouths. This fish is simply terrifying! It has one mouth on its face, one on its neck, and a bizarre tail. It has a weirdly round body
that shouldn't belong to a fish. But even more creepy is the
fact that it has an odd, bulbous protrusion that appears to be filled with some sort of liquid. The fisherman who caught it speculated that the liquid could be eggs, meaning that there was the possibility of more of these creatures. This isn't the first fish of
its kind to be caught though. A Reddit user posted a video that appeared to show a two-headed fish. For a bit, speculation
was all over the internet about what it was and
how it had come to be. It wasn't a conjoined twin, and it hadn't grown up
near a nuclear plant, as neat as that would be. Experts said it was a grass
carp that had been deformed. The second mouth was
actually a large hole formed because the gill arches
weren't connected to its mouth. There was also a fish caught in Australia that had two mouths. Garry Warwick, the fisherman
who landed this bizarre catch, caught the fish in Lake
Bonney, South Australia. He told ABC "Both mouths are
actually joined together. "The top one opens and closes, "but the bottom one
looks permanently open." Although he's been a commercial
fisherman for over 30 years, he says he's never seen
anything like this. Facial deformities in which
the creature or person has more than one of a
particular facial feature, in this case two mouths,
is called diprosopus. It's commonly associated
with conjoined twins, although it's not the result
of two embryos fusing together, nor is it the result of
them not fully separating. It's caused when facial
patterning acts abnormally. Unfortunately, creatures
with two faces don't usually survive because they
usually have some degree of deformation in their
internal organs as well. Number three, fish with human teeth. An emperor fish was
caught by a schoolteacher in the West Papu region of Indonesia. The teacher was astounded
to find that the fish had flat, molar-like
teeth that looked human. He gave the fish to a student, who took it home to his family. They were all equally shocked when they discovered its teeth. Rather than eat the fish, they decided to freeze and preserve it. That's probably a good thing because whatever unholy alliance
that was forged in order to create this fish is probably
not safe for ingestion. Number two, the monsterous
fish from Thailand. A Thai fisherman was out fishing and hoping to catch
something worthy of a meal. Instead, he pulled in something
that is pure nightmare fuel. This fish has a long body
that looks a bit like an oar, a giant mouth filled
with sharp-looking teeth, and, probably most notably,
it doesn't seem to have eyes. No one knows quite what it is. But, the bigger mystery here is where are its eyes and how does it see? Number one, bird fish. This bizarre fish was recently
caught in a river in Guizhou. It looks like a completely
normal fish on the bottom half, but the head is where things get mad. Some people say that it looks a bit like the face of a pigeon. Others say it looks like
the face of a dolphin. What it definitely does not look like is the ordinary head of a
carp that matches its body. Some people blame its apparent deformation on water contaminants. Others think that this is
some sort of hybrid creature, but those in favor of the hybrid theory are not in agreement with what animals parented this bizarre creature. Unfortunately, testing cannot be done to shed light on its parentage, either, as the fish was released back
into its natural habitat. What exactly is a bird fish's
natural habitat anyway? Did it fly away or swim? Most of the entries on this list died, either before or after discovery, which makes for an alarming mystery. What entry did you think
