Description

The finless snake eel is a snake eel of the family Ophichthidae from tropical seas on both sides of the Atlantic Ocean. The species reaches about 45 cm and has an extremely slender, snake-like body that is almost entirely finless; the pectoral and caudal fins are also absent, to which the name refers. With its hard, pointed tail it burrows backwards into sandy bottoms, especially in the turbulent surf zone. There it lives largely hidden and hunts small bottom invertebrates and fishes. Owing to its burrowing habits the species is rarely seen.
