Drymarchon corais

The Indigo snake (Drymarchon corais) is a species of snake of the family Colubridae. This large colubrid snake is nonvenomous and is immune to other snakes' venom, which allows it to prey on venomous snakes smaller than itself. This snake is found in South America, including Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname and Venezuela as well as Trinidad Its diet consists of birds, small mammals, turtles, amphibians, lizards, eggs, and small venomous snakes. It suffocates its prey strongly pinning them against the ground. Until recently, all Drymarchon were classified as subspecies of D. corais. However, North and Central populations are now assigned to different species (D. melanurus, D. couperi and D. kolpobasileus), and D. caudomaculatus and D. margaritae are recognised as separate species in South America.
