Caecilians: odd little amphibians.

Caecilians (Gymnophiona) are amphibious creatures that look like wormy snakes, some bear eggs, some bear live young and some do a combo of both (babies hatch from eggs inside the mother and are later born).

They are curious animals..... here's a couple links to pages devoted to the things: University of TX and Florida International University

And an article about them on the BBC website in which one species is described. The mother in this species develops a nutritious layer of skin which her offspring eat: BBC

So, these critters have jaws, two rows of pointed teeth. They have retractable tentacles at the front of their heads and weak or no eyesight. They sometimes have scales below their wrinkled/segmented-looking skin. There are many species and are found in almost all tropical areas. But, they aren't seen so much because they live under ground.
