Genus Leptaulopus

A genus of threadsails differing from the other three genera of the family most noticeably in having a more slender body, a more posteriorly placed dorsal fin, and finer, more cardiform teeth in the jaws.

Leptaulopus is from the Greek leptos for ‘slender’ and aulopus, a name long applied to the broader group of fishes to which the genus belongs, in reference to the slender form of species in the genus.
