The Dalatiidae are the family of kitefin sharks of the order Squaliformes (the term "kitefin shark" also refers specifically to the species Dalatias licha).

Though eight genera are in this family, four of them are monotypic.

Mollisquama mississippiensis

Dalatias is a genus of kitefin sharks that have lived since the Middle Eocene. The genus contains one extant and two extinct species: D. licha (the type species), D. turkmenicus and D. orientalis. Because D. turkmenicus was described on the basis of a single tooth crown, D. licha was considered as the only valid species within the genus until Malyshkina et al. (2023) described a third species, D. orientalis, from the Middle Miocene Duho Formation in Pohang, South Korea.
