Coqui Frogs are relatively small, secretive tropical to sub-tropical frogs consisting of at least 16 or more species occurring in Puerto Rico and the Caribbean, as well as elsewhere in the neotropics from Central to South America depending on the species. 
The most widespread and well known species is the Puerto Rican Coqui Frog (Eleutherodactyus coqui).
Coqui Frogs have also been accidently introduced as cargo, plant, and shipment hitchhikers, or through accidental or intentional pet releases and escapes widely in other areas as well.
Coqui Frogs are named for their very loud, two-pitched “co-qui” calls typically made at dawn, dusk, and nighttime.
