The dwarf coquí or elfin coquí (Eleutherodactylus unicolor, in Spanish coquí duende) is a species of frogendemic to Puerto Rico.[2] It is placed in the subgenus Eleutherodactylus.[3]
Description
The dwarf coqui is a small frog with a grayish-brown back, a black-mask like face, and a series of light dots that follow through to the posterior of the frog.[4] The females have a light line across the eyelids and usually have “white dots along the face, flanks, forelimbs, and thighs.”[4] The Eleutherodactylus species do not have webbed feet. These frogs, especially the dwarf coqui, have individual, finger-like feet, with round, disc-like toes.[4]E. coqui is often referred to as the “coqui,” which originates from its distinctive call.[5] The “coqui” frogs are known for the unusual sounds they make. “The call of the dwarf coqui has been compared to the sound of a fingernail being dragged across the teeth of a comb or the winding of a watch.”[4]
