Glass Frog

There are at least 60 different types of glass frogs and, as one might expect, their appearance can differ in the details, however, most share common characteristics. Glass frogs are lime green with translucent abdominal skin that, upon close inspection, will allow a viewer to see its organs, including its intestinal tract, heart, and liver. Glass frogs range in size from 1.2 to 3 inches in length. The translucent skin of the Glass frog is thought to be a trait evolved for the purposes of camouflage. Indeed, these tiny creatures truly do seem to melt into the leaves. One can see why predators would have a tough time finding them. However, due to their small size, glass frogs are easy target for large predators such as snakes, mammals and birds.

Glass frogs make their home in the tropical rainforests and montane cloud forests of Central and South America. (Montane cloud forests are a type of forest characterized by persistent low-level cloud cover. They are also known as “mossy forests” and usually develop on the sides of mountains.) Glass frogs reside high up in the treetops of the forests they inhabit. They rarely venture down from the canopy. The Glass frog is nocturnal, spending its days asleep in the vegetation of the forest and its nights hunting for food. Glass frogs mainly feast upon spiders and soft-bodied insects. To catch their prey, Glass frogs hold their mouths open and leap forward, capturing their meal.
