Conger is distinguished from eel by its long dorsal fin that begins at the end of the pectoral fins. The skin is scaleless and covered with a thick mucous. Its head is slightly flattened and its mouth filled with small, pointed and very sharp teeth.
The conger is a completely nocturnal fish that lives in shallow waters. Its color varies according to its habitat. It's rare to find specimens weighing over 20 kg (44 lb.) near the shore. The largest adults weigh more than 60 kg (132 lb.) On the other hand, young congers are an important part of the fauna along the coasts.
Culinary: They're highly prized in Europe and Japan for their rich, firm meat and terrific flavor.
