Conger is a genus of marine congrid eels. It includes some of the largest types of eels, ranging up to 2 m (6 ft) or more in length, in the case of the European conger. Large congers have often been observed by divers during the day in parts of the Mediterranean Sea, and both European and American congers are sometimes caught by fishermen along the European and North American Atlantic coasts.
The Congridae are the family of conger and garden eels. Congers are valuable and often large food fishes, while garden eels live in colonies, all protruding from the sea floor after the manner of plants in a garden. The family includes over 220 species in 32 genera.
Bassanago is a genus of marine congrid eels.
Gnathophis habenatus, the little conger eel or silver conger, is a conger of the family Congridae, found on soft bottoms of the continental shelf of the Indian and southwest Pacific Oceans. Length is up to 43 cm.
Leptocephalus is a genus that was used for species of larval eels, called leptocephali. Leptocephali larvae differ so much in appearance from their adults. When first discovered, leptocephali were thought to be a distinct type of fish, not an eel specie. Because of this, the genus designation of Leptocephalus was used for a while for an unidentified leptocephali. After it was known that these were eel larvae, it was identified to be part of a wastebasket taxon, but not anymore in the present classification system. Examples of marine congrid larvae, found in the western Indian Ocean and the Red Sea that were named this way are listed below. Only two species in two families are currently treated as having any validity, though the validity of L. bellottii is strongly in doubt.
Ariosoma is a genus of marine congrid eels.
