Snake eels are also burrowing eels, they are named for their physical appearance, they have long, cylindrical, snake-like bodies. This family is found worldwide in tropical to warm temperate waters.

Most species are bottom dwellers, hiding in mud or sand to capture their prey of crustaceans and small fish, but some are pelagic.
