Caeciliidae is the family of common caecilians. They are found in Central and South America, equatorial Africa and India. Like other caecilians, they superficially resemble worms or snakes.

Although they are the most diverse of the caecilian families, the caeciliids do have a number of features in common that distinguish them from other caecilians. In particular, their skulls have relatively few bones, with those that are 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.
