While they may look scary, most of them are inoffensive to humans—as long as you don’t poke one of them with your finger, of course!

Chicken snake is a harmless jungle snake that grows up to an average of 5 feet in length. It’s otherwise referred to as the caninana and yellow rat snake.

It belongs to the non-venomous snake species, and warm environments enhance its food digestion, so being an Amazon snake is actually perfect for this species.

Beyond that, chicken snakes feed on rodents, like rats, mice, voles, and chipmunks. They also eat frogs, birds, lizards, and bird eggs. Besides, they create their defense by mimicking the venomous rattlesnake.

When hunting for prey, they intentionally and passionately forage for that prey and lay an ambush against it.

2. Emerald tree boa (Corallus caninus)

The green anaconda is the biggest snake on the planet – not because it is exceptionally long, but because it is the heaviest snake.

This incredible snake from the rainforest can grow up to a whopping 20-30 feet long, and it can weigh up to 550 pounds. It’s a beast!

Because the green anaconda is the world’s most enormous snake, its top speed is only 10 mph (nothing like JLo’s movie, huh? Still, it’s an interesting Amazon fact.).

While this Brazilian animal has an olive body with black spots, its head has orange-yellow stripes on both sides.

With a muscular body, the giant anaconda is an apex predator that feeds on other reptiles, fish, birds, sheep, deer, capybaras, caimans, and even jaguars.

As with any boa constrictors, the anaconda is non-venomous, so it constricts the prey until at least unconscious before swallowing it whole.

Lastly, the anacondas live in the Amazon Basin, especially the first streams, like the Amazon River.

Rainforest snake fact: Female anacondas are on average 4.7 times larger than males. That is the most significant size difference between genres in any land-living vertebrate. Also, the females strangle males after mating.
