Description
E. cooki is a medium sized species, averaging 37mm. The color is brown and the males have a yellow patch in the throat. The eyes and the digital disks are large compared with other Eleutherodactylus (Rivero 1998) .

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Puerto Rico

 

View distribution map using BerkeleyMapper.
This species is limited to southeast Puerto Rico. It inhabits caves that are formed in the spaces between large granite boulders and some rivers with rocky shores. (Rivero, 1998; Vega-Castillo, 2000).

Life History, Abundance, Activity, and Special Behaviors
The male guards the egg clutches of an average size of 17 eggs. Up to four clutches from different females are guarded together, evident by the development stage of the eggs. (Burrowes, 2000).

Trends and Threats
Stable populations have been found and one study found high genetic variabilty, possibly due to movement of individuals between populations (Vega-Castillo, 2000; Burrowes & Joglar, 1999). Urban developments and road constructions could threat the limited habitat of this species.
