Description

The serpent eel is a very long, thin snake eel of the family Ophichthidae reaching about 2.5 metres. The round, greyish to brownish body has a pointed, beak-like snout with a wide toothed mouth and a hard, finless, pointed tail. With that tail tip the fish bores backward into the sand, so it can hunt and shelter while buried. The species lives on sand and mud bottoms of the eastern Atlantic and the Mediterranean, from shallow water to several hundred metres. From its hiding place it seizes small fish and crustaceans. Like all eels it develops through a transparent, leaf-shaped leptocephalus larva. Because of its hidden lifestyle it is only rarely seen.
