Male blue eyed tink, Eleutherodactylus urichi urichi, calling to attract a mate. Its paired vocal sacs are expanded to produce a sound characteuristic of the species; this ensures that the correct females respond. These frogs have done away with the need for water altogether. They lay clutches of gelatinous eggs in damp crevices on land and these hatch directly into froglets. The evolution of a terrestrial breeding habit was probably responsible for the great success of this genus. The different species are difficult to identify as most are small & brown & very similar in appearance. This specimen comes from Trinidad (1982) but they are also found in Tobago.
