They are found in the equatorial countries of [[South America]]. They are usually said to be the most [[primitive]] of the caecilian families. They have many features other groups do not. For example, they still have a tail, and the mouth is not to the back on the underside of the head. They lay their eggs in small holes in the soil. The [[larvae]] have external gills. They live in seepages until they change into adults. The adults live in moist soil and leaf litter.<ref name=EoR>{{cite book |editor=Cogger, H.G. & Zweifel, R.G.|author= Nussbaum, Ronald A.|year=1998|title=Encyclopedia of Reptiles and Amphibians|url=https://archive.org/details/encyclopediaofre0000unse_h2i0|publisher= Academic Press|location=San Diego|pages= [https://archive.org/details/encyclopediaofre0000unse_h2i0/page/54 54]–55|isbn= 0-12-178560-2}}</ref> ==Taxonomy== There are nine species in two genera.
