''Leptocephalus'' is a genus that was used for species of larval eels, called leptocephali, that were thought to be new fish species, or whose adult eel species were not known. Leptocephali differ so much in appearance from their adults that the larvae and adults of eels are not easily matched, and when first discovered, leptocephali were thought to be a different type of fishes,〔Miller, Michael J. “Ecology of Anguilliform Leptocephali: Remarkable Transparent Fish Larvae of the Ocean Surface Layer.” Aqua-BioScience Monographs 2 (2009): 1-94. Web. 2 Nov. 2012.〕 but not eels. Because of this, the genus designation of ''Leptocephalus'' was used for a while for unidentified leptocephali even after it was known that these were the larvae of eels thus becoming a "wastebasket taxon", but this practice is no longer used. 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 (''L. bellottii'' and ''L. ophichthoides'') in two different families are currently treated as having any validity though that of ''L. bellottii'' is strongly in doubt. ==Species== There are 16 different families of leptocephalus organisms that include over 70 different species.〔(Species of Leptocephalus Genus ) Fishbase.org〕 They will be broken down according to the species that they contain. If the species has a common name or English name, it will be given after a dash. A common name can belong to many species.
