Order - Gymnophiona
The Caecilians are an order of amphibians that resemble earthworms or snakes. They mostly live hidden in the ground which makes them the least explored order of amphibians, and widely unknown. Caecilians have degenerate feet, making the smaller species resemble worms, while the larger species with lengths up to 1.5 m resemble snakes. The tail is short and the anus is near the end of the body.
