The conger is a large eel known to reach a length of 9 ft. (2.4 m) and a weight of 143 lb. (65 kg). It is easily distinguished from the moray eel by the presence of pectoral fins, which the moray lacks. It also has a longer snout, its upper jaw is slightly longer than its lower jaw, the head is narrower in appearance, and the dorsal fin does not extend quite as far forward as in the moray.

They inhabit relatively shallow waters in the vicinity of cover material such as rocks, reefs, pier pilings, and especially shipwrecks or other submerged objects suitable as hiding places. They are know to eat octopus, lobsters, crabs, and many types of reef fishes.

Fishing for conger is extremely popular in Britain. It�s great strength, sharp teeth, ability to swim backward, and propensity for remaining in or near cover make it a formidable foe. They should be considered dangerous when boated or speared as their teeth are strong and sharp. They are considered excellent food fish.
