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

Class Amphibia

This class has several subclasses.

  • Order Caecilia
    Not snakes.

    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.

    Caecilians are currently classified into six families.
    • Family Rhinatrematidae
    • Family Ichthyophiidae
