The Amazon rainforest is one of the most dangerous places in the world. It’s interesting that there are still tribes that live there without any modern technology, and seem to go on without much issues. But that’s mostly due to the fact that they’re aware of all the dangers lurking from the shadows. But in case you end up lost in Amazonia for some reason, we’ve compiled the top 20 dangerous animals, just so you know what to avoid.
Green Anaconda Snake
These powerful snakes can weigh up to 155 lbs, and reach up to 17 feet in length. They’re pretty slow on land, but if you meet one in the water your days are numbered. Although not poisonous, their sheer strength allows them to suffocate wild pigs, jaguars and occasionally a human as well.
These piranhas inhabit the Amazon River Basin, and they’re well known for their awfully sharp teeth that can really do damage. They’re not really too dangerous for humans, but if they get really hungry no one is safe. On top of that, they usually hunt in groups, which is why they can take down far larger animals than themselves.
If you suffer from arachnophobia, let me first apologize for scaring you. However, it’s good to know that there are over 3600 species of spiders in the Amazonian rainforest. Tarantulas attack with poisonous venom, and they can also cause damage to the victims eyes by shooting tiny hairs at them. These hairs are like fiberglass, and they can penetrate the eye socket and cause serious damage. So yeah, think twice before taking that trip.
Arapaima is the largest scaley freshwater fish in the entire world. It can weigh 440 lbs and be over 15 feet in length. It’s also considered to be a specialty in these parts, and the locals love to hunt them down due to the quality of it’s meat.
Amazonian Giant Centipede
These centipedes might look nasty, but they rarely attack humans. When they do, the venom can be really unpleasant, causing severe pain, fever and swelling. They can grow up to one foot long, and easily take down mice, frogs, birds and smaller snakes.
Bull sharks can grow up to be huge, and they have little prejudice when it comes to prey. The cool thing about them is that they can actually go into fresh water, unlike other sharks that need to retain salt inside their bodies to survive.
The electric eel can shoot a powerful electric discharge of around 300-650 volts through it’s tail, which is usually enough to take down even the toughest opponents, including alligators. They usually don’t attack humans, but if it feels threatened no one is safe around these bad boys.
Black caiman can grow up to be 20 feet long. They are the largest predator in the Amazonian ecosystem, and they have the tendency to attack humans. There was a story a few years ago about a black caiman attacking a man on the canoe. He first flipped over the canoe and then grabbed the man by his leg and tried to pull him under water. Luckily the man grabbed a paddle and knocked him over the head with some force, managing to survive the encounter.
Probably the ugliest animal on Earth, pacus are known for their human-like teeth. They can also grow around 4 feet long. But not to worry, they’re actually vegans, eating only fruits and nuts. However, there are some stories of human testicles being a pacu’s cheat meal specialty. It’s still being debated whether those stories are true or not, and I’m sure we’d all like to believe it’s a product of someone’s twisted imagination.
Being bitten by a bullet ant feels like being shot, hence the cool name. There is also a tribe in Amazonian rainforest called Satere-Mawe which uses bullet ants in their initiation to the warrior class. The young male has to put his hand in a glove made of leaves in which there are bullet ants. The pain and suffering from the bites can last for days during which the hand is paralyzed and sometimes shakes uncontrollably. If you want to prove you’re tough, all you need is a glove and a bullet ant.
Poison Dart Frog
These frogs are most deadliest animals of the rainforest. Just one milligram of their poison is enough to end a human life. Hunters from various tribes use their venom to imbue their arrows, and the poison remains potent for a whole year.
Jaguars are fast and powerful, and also the third largest cats in the world. They’re also not afraid to go up against the largest predators, including alligators and anacondas. Unfortunately, they are also caught for their fur and they’re losing their habitat due to pollution and agricultural expansion.
These huge venomous snakes can grow up to be 12 feet long. Their specialty is attacking from the trees, leaving the prey little option to act in self-defense.
In the Amazonian rainforest, no part of your body is safe from predators. This small creature can actually get into your urethra and plow through to the male testicle, as has been observed in one documented case. However, they usually just attach themselves to larger fish and feed on their blood.
Payara (Vampire Fish)
These awful predators are known for devouring victims that are twice as large. With their huge, sharp teeth they can literally impale their prey before tidying up the business. Their specialty are piranhas, so that gives you a clue on just how tough the vampire fish really are.
They might look like they’re harmless, but giant otters (can grow up to 6 feet long) are very capable hunters that can match any of the animals on this list. They sometimes even go in battle against anacondas and caimans and end up winning. This is however, largely due to them attacking in groups. Still quite impressive though.
The assassin bug has a trunk-like organ potruding from it’s mouth that it uses to inject a powerful venom. This venom basically melts down the internal organs of it’s prey. Although humans are too large for it to have such a potent effect, it can still leave a very nasty and painful bite so it’s best to avoid them if possible.
The harpy eagle has very little competition in the air. It can surge downwards and attack monkeys, sloths, squirrels, anteaters and various other prey with ease. It rarely attacks humans, unless it feels that it’s nest is threatened by their presence.
Brazilian Wandering Spider
Not the worst predator on the list, but awful nonetheless, the wandering spider is a nocturnal predator that wanders across the ground during nighttime in search of food. It shoots poisonous venom, which can be quite nasty for animals and humans as well.
Sure, they’re small and you can squash them with your bare hand. But these annoying pests are actually the deadliest creature of the rainforest as they carry malaria and similar deadly diseases. They’re also becoming increasingly resistant to insect repellents like Deet, making them an even bigger threat than before.
