Caicos Least Gecko

Sphaerodactylus caicosensis reaches a snout–vent length of 32 mm (1.3 in). It is sexually dimorphic in the color of its back.

Sphaerodactylus caicosensis is endemic to the Turks and Caicos Islands, an overseas territory of the United Kingdom located in the Lucayan Archipelago in the northern Caribbean. It is found on all of the larger islands in the Caicos Islands from South Caicos to West Caicos, as well as smaller outlying islets, like Long Cay off the shore of South Caicos. It prefers arid habitats near beaches, where it hides under debris such as rocks. It can also be seen in more moist places like tropical dry forest. This gecko is generally encountered sitting on rocks or small plants. They are extremely tolerant of human settlements and can frequently be encountered on rock walls or near houses. It lays eggs.
