Sphaerodactylus sputator. Their common name, the island least gecko, refers to their small size and the fact that they inhabit several islands. Hatchlings are over an inch long, with adults reaching nearly 3 inches; one of the larger micro geckos, but still very small. It is estimated that these geckos live for 10-20 years in captivity. Juveniles are gray-brown with brown markings and a bright orange to red tail. Adults keep similar dark brown to black markings, but become lighter with a light brown to beige background and yellow tail. Males exhibit bright yellow heads.
