Common Names

The green anaconda is commonly called a water boa, anaconda, or common anaconda. The local names of the biggest snake include the following: ‘matatoro’ in Spanish which means ‘bull killer’, ‘sucuri’ in Native American and ‘yakumama’ in Peruvian that both mean ‘mother of the water’, and ‘huille’ or ‘huilla’ in Trinidad.

Behavior of the Biggest Snake

In general, green anacondas are nocturnal and love to spend most of their lifetime in or around watery areas. That is the reason why they are also called as the water boa since they spend more of their time in water compared to other boa species. These snakes are absolutely slow and sluggish when they travel on land due to their enormous body size. However, when they are in water, they have the capacity to move with great speed in any depths. They have the skill to float on the water surface but their nose is just barely poking out over the water surface.


As the biggest snake, green anacondas are using constriction to overpower their prey. A hungry anaconda will grab its prey using its jaws and then coil around the prey using its large body. It will then constrict until the prey becomes suffocated and dead.

Since they are aquatic in nature, they have a wide selection of prey. They take in animals that they can overpower easily like birds, fish, other reptiles, and some kinds of mammals. Those very large green anacondas can consume huge preys like deer, tapir, other snakes, capybara, jaguars, and caimans. However, feeding on large preys are not done habitually. Cannibalism among the world’s biggest snake is also evident because there are recorded instances wherein larger female anacondas are consuming the smaller male of their kind.
