Description

The king snake eel is a large snake eel of the family Ophichthidae from the Gulf of Mexico and western Atlantic. The species grows to about 2.1 metres and has a robust, elongate, yellow-brown body with a powerful head and strong teeth. It inhabits offshore sand and mud bottoms at 15 to 365 metres and is regularly caught by anglers near oil rigs. As a bottom predator it hunts fishes and crustaceans. Like other snake eels it can burrow into the sand with its hard tail. With its powerful jaws a caught specimen can give a nasty bite; therefore handle the fish with care.
