X-ray showing the skeleton of Typhlonectes (Typhlonectidae). Caecilians' anatomy is highly adapted for a burrowing lifestyle. In a couple of species belonging to the primitive genus Ichthyophis vestigial traces of limbs have been found, and in Typhlonectes compressicauda the presence of limb buds has been observed during embryonic development, remnants in an otherwise completely limbless body.

Atretochoana eiselti is a species of caecilian originally known only from two preserved specimens discovered by Sir Graham Hales in the Brazilian rainforest, while on an expedition with Sir Brian Doll in the late 1800s, but rediscovered in 2011 by engineers working on a hydroelectric dam project in Brazil.
Caeciliidae is the family of common caecilians.They are found in Central and South America. 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.
The Ceylon caecilian grows to about 23 to 40 cm (9.1 to 15.7 in) long and resembles a large earthworm. The skin is formed into over 300 transverse folds which give the caecilian the appearance of being segmented. The head has a rounded snout and a pair of extensible tentacles near the mouth, rather closer to the eyes than to the nostrils. The ...
The Ichthyophiidae are the family of Asiatic tailed caecilians or fish caecilians found in South and Southeast Asia as well as southernmost China. [1] They are primitive caecilians, lacking many of the derived characters found in the other families. For example, their mouths are not recessed underneath their heads, they possess tails, and they ...
Typhlonectidae, also known as aquatic caecilians or rubber eels, are a family of caecilians found east of the Andes in South America. [ 1 ] They are viviparous animals, giving birth to young that possess external gills.
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 ...
Caecilians are some of the least studied amphibians. Not much is known about their behavior and life history. Siphonops annulatus is highly fossorial, spending most of its life burrowed underground. A study found tunnels made by this species to go no deeper than 20 cm. This species uses a highly ossified skull to help burrow into the ground. [5]
