Puerto Rican Upland Sphaero

Sphaerodactylus klauberi is one of the larger-sized Sphaerodactylus species. It may attain a snout-to-vent length (SVL) of 37 mm (1.5 in). Its colorings consist of a dark-brown upper body with darker-brown or black spots which become larger on the tail. The underbody is usually orange or reddish-pink with a gray throat that may have dark mottled areas.

S. klauberi specimens have been collected between 160 ft (50 m) and 3,600 ft (1,097 m) in elevation. They can sometimes be seen on the ground or on low branches in the Tabonuco, Colorado, and Palma Sierra sections of the Caribbean National Rain Forest.

Like all Sphaerodactylus species, S. klauberi is voiceless. It is mostly active at night.

The epithet or specific name, klauberi, is in honor of American herpetologist Laurence Monroe Klauber.
