During breeding season, males form “breeding balls” around a female. Ovoviviparous — females give birth to 15–40 young.Carnivorous. Preys on fish, waterfowl, rodents (capybaras, nutrias), and small mammals. Juveniles feed on amphibians and small fish.
The genus Eunectes evolved millions of years ago in South America and belongs to the Boidae family, which dates back to the Cretaceous period.
Anacondas are part of South American folklore, often portrayed as giant mythical snakes. They are popular in movies and literature. Studied by herpetologists as key predators in wetland ecosystems.
IUCN Conservation status – Least Concern. Populations are stable, but habitat destruction and hunting pose threats.
