Introduction to Glass Frogs
Overview of the Species
Glass frogs belong to the family Centrolenidae, a group of amphibians known for their distinctive transparent skin, particularly on their bellies. This unique feature allows for a glimpse of their internal organs, including their heart, liver, and digestive system. There are over 150 species of glass frogs, primarily distributed across the tropical rainforests of Central and South America. These frogs are often small, with sizes ranging from about 2.5 to 7.5 centimeters in length, depending on the species.
The most commonly recognized species is the Cochranella granulosa, often referred to as the green glass frog due to its vivid green coloration and the striking appearance of its transparent skin. Other notable species include the Hyalinobatrachium fleischmanni, known as Fleischmann's glass frog, and the Hyalinobatrachium valerioi, which showcases similar striking features.
Glass frogs are primarily arboreal, residing in the foliage of trees and shrubs near streams and rivers. Their habitats are typically humid, providing the moisture necessary for their survival and breeding. The transparency of their skin is an evolutionary adaptation that offers an advantage in avoiding predators. By blending into their surroundings, these frogs can evade the watchful eyes of birds, snakes, and other potential threats.
