Description

The thinlip conger is a small, slender conger eel of the family Congridae reaching about 60 cm. The round, grey-brown body has large eyes, thin lips and a continuous fin fringe in which the dorsal, tail and anal fins merge. The species lives on sand and mud bottoms of the continental shelf and slope of the eastern Atlantic and the Mediterranean, usually between tens and eight hundred metres. By day it buries itself in the soft bottom; at night it emerges to hunt small crustaceans, worms and small fish. Like other eels it develops through a transparent, leaf-shaped leptocephalus larva. Because of its small size it has no fishery importance.
