The Common Liana Snake, Siphlophis cervinus (pictured here from Amazonian Peru), is an uncommon, nocturnal and mostly arboreal snake (< 1 m total length) that is found in humid lowland rainforests of Panama and South America including Trinidad and Tobago. While much of its natural history remains a mystery, lizards are known to be a regular part of the diet of S. cervinus. Juveniles, upon hatching, are identical in color and pattern to the adults. Siphlophis cervinus is one of seven Siphlophis species that are found in Central and South America.
