Quick Summary

The yellow anaconda (Eunectes notaeus) is a species of large, water-loving snake native to South America. Unlike the much larger green anaconda, the yellow anaconda is considerably smaller, with adult females typically reaching about 4.4 to 4.6 meters (14.4 to 15.1 feet) in length. These snakes are characterized by their yellowish coloration, marked by pairs of overlapping black spots. They inhabit swamps, marshes, and other aquatic environments. Yellow anacondas are carnivorous predators that feed on smaller vertebrates and carrion. They are constrictors, killing their prey by coiling around it. Females give birth to live young, usually around 40 offspring, and do not lay eggs.12
