Dermophis mexicanus, also known commonly as the Mexican burrowing caecilian or the Mexican caecilian, and locally as the tapalcua or tepelcua, is a species of limbless amphibian in the family Dermophiidae. The species is native to Mexico and Central America, where it burrows under leaf litter and plant debris.
The snout of the Sagalla caecilian is rounded, with short, globular tentacles, and a relatively large mouth, with two rows of teeth in each jaw. The eyes in some are highly reduced, and, sometimes, almost entirely covered by bone and skin. The eyes may form like this due to the lack of need for vision, beyond sensing light, while digging.

Caecilians feed on small subterranean creatures such as earthworms. The body is cylindrical and often darkly coloured, and the skull is bullet-shaped and strongly built. Caecilian heads have several unique adaptations, including fused cranial and jaw bones, a two-part system of jaw muscles, and a chemosensory tentacle in front of the eye. The ...
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 ...
One of nearly 200 caecilian species, Kaup’s aquatic caecilian is a legless amphibian. As Baker said, “It’s very odd because most people are unfamiliar with a legless amphibian.”
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 Cayenne caecilian lives in shallow streams and rivers. It spends the day in a communal burrow, emerging at night to hunt through the sediment for small invertebrates, such as insect larvae and shrimps. It also eats small fish. It has no functional eyes and probably detects its prey by touch or by the vibrations made when the prey moves. It ...
