About the Prado's Coastal House Snake

The Prado's Coastal House Snake belongs to the Dipsadidae family, dipsadid snakes. A huge New-World group of mostly rear-fanged, mostly harmless snakes.

Dipsadids are an enormous, mainly Neotropical radiation that includes hognose snakes, snail-eaters, false coral snakes, and many more. Most are rear-fanged but harmless to people. (Many sources still file these snakes under Colubridae, so our family counts reflect that older arrangement.)

Its genus, Mesotes, covers coastal house snakes. Mesotes is a tiny South American genus of harmless coastal ground snakes in the vast Dipsadidae family.

The Prado's Coastal House Snake is non-venomous and harmless to people. Like most snakes it is a quiet predator that helps keep rodents and other small prey in check.
