Dipsadinae
Dipsadinae
a subfamily of reptiles of the family Colubridae. The body measures as much as 1 m in length. The head is short and thick, and the neck is very slender and long. The torso is somewhat compressed laterally. There are three genera, including approximately 50 species, which are distributed in Central and South America. The Dipsadinae live in trees. When in danger, some species deceive predators by falling to the ground and lying still, resembling a dry branch. The Dipsadinae feed mainly on mollusks, which they draw out of their shells with the long, slender teeth of the lower jaw. They also feed on insects and their larvae. The female lays eggs.
