Brasilotyphlus Luetkenotyphlus Microcaecilia Mimosiphonops Siphonops The Siphonopidae are the family of common caecilians.

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.

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.
