What is the green anaconda?
The green anaconda (Eunectes murinus) is a species of snake in the family Boidae (boas). The species is native to northern South America. It is one of the longest and heaviest known extant snake species. Like all boas, it is a non-venomous constrictor. The green anaconda generally has a life expectancy of ten years in the wild, although some specimens live longer when taken care of in captivity. The green anaconda lives in tropical rainforests and tends to prefer shallow, slow-moving waters, such as streams, rivers, and flooded grasslands. It spends most of its time in the water but is also found on land in thick vegetation.
