Anolis cooki

Anolis cooki, also known commonly as Cook's anole, Cook's pallid anole, and the Guanica pallid anole, is a species of lizard in the family Dactyloidae. The species is endemic to Puerto Rico.

Etymology
The specific name, cooki, is in honor of Melville Thurston Cook (1869–1952), who was an American botanist and entomologist.

Geographic range
A. cooki is found in southwestern Puerto Rico, including the island of Caja de Muertos.

Habitat
The preferred natural habitat of A. cooki is forest, at altitudes from sea level to 100 m.

Description
Moderate-sized for the genus Anolis, males of A. cooki may attain a snout-to-vent length (SVL) of 7 cm. Females are smaller, attaining 6 cm SVL.

Reproduction
A. cooki is oviparous.

Taxonomy
A. cooki was originally described as a subspecies of Anolis cristatellus but raised to species rank in 1966. In 2012 Nicholson et al. "split" the genus Anolis and placed A. cooki in the genus Ctenonotus, a move which has not been widely accepted.
