Snakes in the Amazon rainforest eat whatever fits in their mouths, and what that is depends on the species. Big constrictors like anacondas eat large animals such as capybara, caiman, and fish. Smaller snakes eat frogs, lizards, birds, rodents, or even other snakes. All of them swallow prey whole.
Anacondas
Green anacondas live in and near water. They ambush fish, birds, capybara, caiman, turtles, and sometimes deer or peccaries, then kill by constriction. Large prey can feed a snake for weeks.
Boa constrictors and tree boas
- Boa constrictors eat rodents, opossums, birds, and lizards.
- Emerald tree boas ambush birds, small mammals, and lizards from tree branches.
- Rainbow boas hunt rodents and birds near the forest floor and water.
Venomous snakes
- Lanceheads and fer-de-lance (Bothrops): strike rodents, lizards, and frogs, and strike and release larger prey so it stays within reach.
- Bushmasters: eat mostly mammals such as rodents.
- Coral snakes: eat other snakes, lizards, and worm-like caecilians.
Snake-eating snakes and small species
- Mussuranas eat other snakes, including venomous pit vipers, and appear largely immune to their venom.
- Vine snakes are slender and eat lizards and frogs.
- Small ground snakes eat insects, worms, and frog eggs.
How they find prey
Snakes track prey by scent, picked up with their forked tongues. Many pit vipers and boas have heat-sensing pits that detect warm prey in the dark. Some hunt actively, and some wait in ambush for hours.
What eats Amazon snakes
Snakes are prey too. Jaguars, harpy eagles, caimans, giant otters, and other snakes eat them, so the forest food web depends on them.
Staying safe
If you travel in the Amazon, wear boots, watch where you step and put your hands, and never handle snakes. Seek medical help right away after any snake bite.

Bottom Line
Amazon snakes range from giant fish-and-caiman eaters to tiny worm-eating species. Their diet follows their size, habitat, and hunting style.
