Scientific Classification of Snakes (And Various Long, Thin, Legless Non-Snakes)

Class Amphibia

This class has several subclasses.

  No, they aren't people from southern Italy, they are the least studied order of living amphibians (Lissamphibians). Caecilians are legless, occasionally eyeless, elongate, annulated, smooth-skinned, burrowing creatures which resemble earthworms about as much as is possible for a vertebrate. They are restricted to the moist tropics but distributed worldwide (except Australia and Madagascar). They are sometimes referred to as Gymnophionans or Apodans.
