Coquí
Coquíes belong to the "Eleutherodactylus" genus which in Greek means free toes. "Eleutherodactylus" contains over 700 different species that naturally occur in the southern United States, Central America, South America, and the Caribbean. Coquíes additionally have become established in Hawaii, where they are considered an invasive species, and have recently been spotted in California after hitching rides among shipments of nursery plants.
