This article is about snakes. For other uses, An anaconda is a large, non-venomous snake found in tropical South America. Although the name actually applies to a group of snakes, it is often used to refer only to one species in particular, the common or green anaconda, Eunectes murinus, which is one of the largest snakes in the world.

Anaconda may refer to: Any member of the genus Eunectes, a group of large, aquatic snakes found in South America. Eunectes murinus, a.k.a. the common anaconda, the largest species, found east of the Andes in Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, Brazil and on the island of Trinidad. Eunectes notaeus, a.k.a. the yellow anaconda, a smaller species found in eastern Bolivia, southern Brazil, Paraguay and northeastern Argentina. Eunectes deschauenseei, a.k.a. the dark-spotted anaconda, a rare species found in northeastern Brazil and coastal French Guiana. The giant anaconda, a mythical snake of enormous proportions found in South America. Any large snake that "crushes" its prey (see Constriction). Applied loosely.

Etymology

The name was first used in the English language in 1768 by R. Edwin in a colorful description of a large snake found in Ceylon (now Sri Lanka), most likely a reticulated python, Pytho reticulatus. The account, which explains how the snake crushes and devours tigers, is full of popular misconceptions, but was much read at the time and so gave rise to the myth of the Anaconda of Ceylon.
