The Amazon rain forest is an immense ecosystem, providing a
habitat for creatures as weird and wonderful as the jaguar, the poison dart frog
and the Jesus lizard. But it’s home to more than just the animals that prowl,
swing, and slither through the trees. In the depths of the Amazon
River, the largest river in the world, live creatures so amazing
and so terrifying, that they makeJaws look like a nice, relaxing swim in the
ocean.
A black caiman is basically an alligator on steroids. They
can grow up to six meters (20 feet) long, with bigger, heavier skulls than Nile crocodiles, and are the apex predator in the
Amazonian waters. That means they are basically the kings of the river - they
eat nearly anything they can get their teeth into, including piranhas, monkeys,
perch, deer, and anaconda. Oh, and yes, they totally attack humans. In 2010, a
biologist named Deise Nishimura was attacked by a caiman while cleaning a fish
on her houseboat, and while she managed to fight it off, it took one of her
legs with it. This particular caiman had been living under her houseboat for
eight months, evidently waiting for the chance to strike.
9- Green Anaconda
Continuing with the theme of gigantic reptiles, the largest
snake in the worldmakes its home in the Amazon: the anaconda. While reticulated
pythons are actually longer, green anaconda are far heavier; the females,
generally larger than males, can reach 250 kilograms (550 lbs), grow to nine
meters (over 29 feet) long and reach 30 centimeters (12 in) in diameter. They
are not venomous but instead use their immense muscular power to constrict and
suffocate their prey, which includes capybara, deer, caiman, and even jaguars.
Preferring shallower waters that allow them to stealthily sneak up on their
prey, they tend to live in offshoots of the Amazon rather than the river
itself.
8- Arapaima
Arapaima, also known as “pirarucu” or “paiche,” are gigantic
carnivorous fish that live in the Amazon and surrounding lakes. Encased in
armored scales, they think nothing of living in piranha-infested waters - and
they are pretty effective predators themselves, feeding on fish and the
occasional bird. Arapaima tend to stay close to the surface, because they need
to breathe surface air in addition to taking in oxygen through their gills, and
make a distinctive coughing sound when they emerge for air. They can reach 2.7
meters (nine feet) in length and weigh up to 90 kilograms (200 lbs). These fish
are so vicious that even their tongue has teeth.
7- Giant Otter
Heading up the “exactly what it says on the tin” category
are the giant otters, who, as their name suggests, are very large otters. They
are the longest examples of the weasel family, with adult males reaching up to
two meters (over six feet) from head to tail. Their diet primarily consists of
fish and crabs, which they hunt in family groups of three to eight members, and
they can eat up to four kilograms (nine pounds) of seafood per day. Don’t be
fooled by their cute looks, though - they are more than a match for the other
animals on this list, with groups of them having been spotted killing and
eating an anaconda. They hold their own against caiman as well. One family was
seen devouring a 1.5 meter (five foot) caiman, which took them about 45
minutes. While their numbers are dwindling, mainly due to human intervention,
they are among the most capable predators in the Amazon rain forest, hence their
local name of “river wolves.”
6- Candiru
The Amazon doesn’t only breed giants, and the small
creatures are just as terrifying, at least if you believe the stories that
surround them. Candiru are small, parasitic, freshwater catfish famous for
launching themselves up the urethra of anyone foolish enough to urinate in the
river, and getting lodged into the urinary tract because of the spines that run
along their backs. While documented cases are rare, and there is some debate
over whether these types of injuries occur at all, there is at least one
documented case of a man requiring surgery to remove a candiru from his urethra
- which had also attempted to burrow through to his testicles. However, the
candiru usually preys on fish, attaching themselves to the larger fish’s gills
with their spines and feeding on their host’s blood.
5- Bull Sharks
While technically ocean-dwelling saltwater animals, bull
sharks are quite at home in fresh water, too - they have been found as far down
the Amazon as Iquitos in Peru, almost
4,000 kilometers (2,500 mi) from the sea. They have special kidneys that can
sense the change in salinity of the surrounding water and adapt accordingly.
And you do not want to meet one of these in the river; it is common for them to
reach 3.3 meters (11 ft) in length and there have been reports of sharks
weighing 312 kilograms (690 lbs). Like many sharks, they have several rows of
sharp, triangular teeth andimmensely powerful jaws, with a bite force of 589
kilograms (1,300 lb). They’re also quite partial to a bit of human, being one
of the most frequent attackers of people (along with tiger sharks and great
whites). Combined with their habit of living near densely populated areas, this
has led many experts to label them the most dangerous sharks in the world.
4- Electric Eels
Electric eels are actually more closely related to catfish
than eels, but you probably wouldn’t want to get close enough to one to find
out. They can grow up to 2.5 meters (eight feet) long and can produce jolts of
electricity from specialized cells called electrocytes arranged down their
flanks. These charges can reach up to 600 volts, five times the charge of an
average American plug socket, and enough to knock a horse off its feet. While
one shock isn’t enough to kill a healthy adult human, multiple shocks can cause
heart or respiratory failure, and it’s common for people to be stunned and
drown after an eel attack. Many of the disappearances recorded in the region
have been attributed to eels that have stunned their victims and left them to
drown in the river. Luckily for our species, the eels, while carnivorous, tend
to stick to eating fish, amphibians, birds, and small mammals. They locate
their prey by sending out small, 10-volt shocks from their electrocyte cells, before
stunning or killing them with larger shocks.
3- Red-Bellied Piranhas
The quintessential terror of the Amazon River, so widely
feared that they have inspired a number of questionable Hollywood
movies, red-bellied piranhas are actually primarily scavengers. That’s not to
say they won’t attack healthy creatures; after all, given that they can grow to
be over 30 centimeters (12 in) long and swim around in large groups, they tend
to be more than a match for most animals. Like all piranhas, red-bellies have
incredibly sharp teeth, one row on each of their powerful upper and lower jaws.
These teeth are interlocking, which makes them perfect for tearing and rending
the flesh of their prey. Their fearsome reputation mainly comes from sights of
their “feeding frenzies,” where groups of piranhas will congregate on their
unlucky prey and strip it to the bone within minutes. These attacks are rare
and are usually the result of starvation or provocation.
2- Payara (Vampire Fish)
Anything with the name “vampire fish” should automatically
be recognized as scary (even after Twilight), and payara are no exception. They
are absolutely ferocious predators, capable of devouring fish up to half their
own body size. Given that they can grow up to 1.2 meters (four feet) long, this
is no mean feat. A large part of their diet is made up of piranhas, which
should give you some idea of how tough these fanged fiends can be. They get
their name from the two tusks that sprout from their lower jaw, which can grow
up to 15 centimeters (six inches) long and which they use to literally impale
their prey after viciously lunging at them. Their fangs are so big, in fact,
that they have special holes in their upper jaw to avoid impaling themselves.
1- Pacu
One animal certain to be far more terrifying to men than to
women, the pacu is a much larger relative of the piranha, known for its
distinctive, human-like teeth. Unlike most of the creatures on this list, the
pacu is actually omnivorous, and a good part of its diet is comprised of fruit
and nuts. Unfortunately for some pacu, “nuts” may not only mean things that
drop from trees. Yes, that’s right: Pacu are alleged to have occasionally
bitten off the testicles of male swimmers, with reports of men in Papua New Guinea
being killed by pacu after the fish apparently mistook their genitalia for an
easy snack. Oh, and don’t worry if you can’t make it to the Amazon to see these
manhood-masticating monsters, because they’re already spreading into Europe.
