Antilles Robber Frog

The average SVL of E. antillensis is 30mm. E. antillensis is easily recognized from other Eleutherodactylus of Puerto Rico because the posterior side of the thighs has a black spottled pattern and the eyes are red. A fine line in the back may be present or absent. The color of the back is brown, varying in intensity although it is commonly a light brown (Rivero 1998) .The males usually call from leaves in protected parts of the plant.

E. antillensis is native to Puerto Rico, the United States Virgin Islands and the British Virgin Islands. In Puerto Rico it occurs almost continuosly in the complete island, with the exception of the highest peaks. This species is common in urban areas, grasslands, and open forest areas, including dry forests (Rivero 1998; Schwartz and Henderson 1991).

The species call from low vegation, usually hidden between leaves. It calls from dusk until dawn, but the activity decreases greatly after midnight (Rivero 1998). Egg clutches are laid in the ground, under a thin layer of leaf litter or soil. Number of eggs per clutch ranged from 24 to 42 and it is possible that the species has parental care (Ovaska and Estrada 2003) .

No information is available. However, since it is very common in urban areas and pastures, it is probably stable. No threats have been identified.

Since the call of this species is very similar to the common coquí (E. coqui), regarded as the national symbol of Puerto Rico, people tend to confuse it for E. coqui. In some urban areas it is the sole anuran present, so people confuse it with the common coquí.
