Siphonopidae
The Siphonopidae are the family of common caecilians. They are found in Central and South America. Like other caecilians, they superficially resemble worms or snakes.
They are the sister group to Dermophiidae, also of South America. Siphonopids are oviparous caecilians, meaning they lay eggs. They have imperforated stapes and no inner mandibular teeth. Like species of some other caecilian families, their skulls have relatively few bones, with those present being fused to form a solid ram to aid in burrowing through the soil. The mouth is recessed beneath the snout, and there is no tail.- Genus Brasilotyphlus
