[1] The snake strikes at its prey and holds on, pulling the prey into its coils or, in the case of very large ...
Anacondas or water boas are a group of large boas of the genus Eunectes.They are a semiaquatic group of snakes found in tropical South America.Three to five extant and one extinct species are currently recognized, including one of the largest snakes in the world, E. murinus, the green anaconda.
The yellow anaconda (Eunectes notaeus), also known as the Paraguayan anaconda, [2] is a boa species endemic to southern South America. It is one of the largest snakes in the world but smaller than its close relative, the green anaconda. No subspecies are currently recognized.

The green anaconda (Eunectes murinus), also known as the giant anaconda, emerald anaconda, common anaconda, common water boa, or southern green anaconda, is a semi-aquatic boa species found in South America and the Caribbean island of Trinidad.

Prey of the northern green anaconda include large animals such as capybaras, caimans and deer. It is a keystone species in its ecosystem, whose presence impacts the habits and migration patterns of other species in the surrounding environment.
A video shared online shows the scale of these 20-foot-long (6.1-meter-long) reptiles as one of the researchers, Dutch biologist Freek Vonk, swims alongside a giant 200-kilo (441-pound) specimen.
Snake venom has a scent that is easily recognized by the snake, allowing the snake to relocate its prey once it has run away and died. While not all snake species in every situation release their prey after envenomation, venom generally assists in prey relocation. [8] Venomous snakes have also been shown to be aware of the relative size of prey.
