Macaw Lodge has many lily ponds which attract all kinds of frogs and dragonflies, but this particular glass frog is arboreal and was see on a vine growing over a little arbor over a bridge over a stream. They are called “glass” frogs because with some you can see inside their bodies and some of their organs. This one was tiny (as most glass frogs), maybe 1.5 inches at most. There are 154 identified glass frogs in Central and South America with 14 known species in Costa Rica. See my Amphibians Costa Rica GALLERY where I have 4 species of glass frogs among about 50 frogs! 🙂 And I am not certain with this particular identification of “Emerald,” but was the best match in my amphibians book! 🙂
¡Pura Vida!
