Takydromus dorsalis, the Sakishima grass lizard, is a species of lizard in the family Lacertidae. It is endemic to the Yaeyama Islands (Ishigaki Island, Iriomote Island, Kohama Island and Kuroshima) in southern Japan.
The name "Takydromus" means "fast-running", derived from greek. "Dorsalis" was inspired by its small, differently arranged dorsal scales that distinguish it from other species.[1]
It is diurnal. The females lay clutches of one to two eggs.
The IUCN lists the species as endangered. Threats consist of habitat degradation and invasive peacocks.
