This small frog represents the most common species from Puerto Rico and most Caribbean islands.
The Eleutherodactylus, as known by its zoological name, exceeds the creature itself in length. The coquí - little frog, as it is called in Puerto Rico, has only a minute tail when it is born, and this quickly disappears. Its length ranges between 15mm-80mm / .5"-3.25" and the color of the coquí varies considerably - green, brown and yellowish, sometimes having touches of different colors or two lateral stripes. The word Eleutherodactylus means in Greek free toes. As the name indicates, this type has no inter digital membrane, which could indicate that they are not adapted to swim. All coquies have disks or pads on the tips of their toes, to help them adhere to surfaces, such as moistened leaves.
