The Dugongidae are a family in the order of Sirenia. The family has one surviving species, the dugong (''Dugong dugon''), one recently extinct species, Steller's sea cow (''Hydrodamalis gigas''), and a number of extinct genera known from fossil records. ==Taxonomy== * Family DUGONGIDAE * * Genus †''Anisosiren'' * * Genus †''Indosiren'' * * Genus †''Miodugong'' (''nomen dubium'') * * Subfamily Dugonginae * * * Genus †''Bharatisiren'' * * * Genus †''Callistosiren''〔Jorge Vélez-Juarbe and Daryl P.

Moreover, Halitheriinae is paraphyletic with respect to Dugonginae and Hydrodamalinae, and further use of the name should be discontinued because the type genus is based on a non-diagnostic tooth.〔M.
