 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 families are currently treated as having any validity, though the validity of "L. bellottii" is strongly in doubt.
