(Eleutherodactylus antillensis)
Eleutherodactylus is a genus of frogs in the family Eleutherodactylidae.Many of the 185 species of the genus are commonly known as "rain frogs" or "robber frogs",due to their sharp,high-pitched,insect-like calls.The best-known species is the common coquí (E.coqui),which is both a national symbol of Puerto Rico and a notorious invasive species in Hawaii.Two Eleutherodactylus species,E.limbatus and E.iberia,are among the smallest known frogs,measuring only 8.5 mm in length (only slightly larger than Paedophryne amauensis,which measures around 7.7 mm).
