The Red-Eyed Tree Frog (Agalychnis callidryas) is commonly known as the “monkey frog” for its jumping abilities. It is a relatively small amphibian, measuring no more than eight centimeters. The male is usually about two and a half centimeters smaller than the female. A colourful amphibian, it is most recognizable by its bright green color and red eyes. Its other markings include blue and cream coloring around the groin and rib areas as well as its orange feet. However, this color pattern is developed with age; the younger Red-Eyed Tree Frogs are mostly brown. Their lifespan in the wild is usually around five years. Red-Eyed Tree Frogs have many characteristics to accompany their climbing habits. Their long limbs allow them to climb and swim with agility as do the sucker pads on the bottom of each digit. The skin on their stomachs is a lot thinner than the skin found on their backs which is more resistant and thick. They have long sticky tongues to help them latch onto their prey for an easier hunt.
The Red-Eyed Tree Frog is not endangered, however the rainforest habitat is shrinking due to a mixture of deforestation, and environmental issues.
The Red-Eyed Tree Frog can be found in the rainforests of Central and South America. They are a mainly arboreal amphibian which means that they are “tree dwelling” frogs. However, as tadpoles, they are found in the water and only with age do they migrate to the trees. They are a nocturnal amphibian and sleep during the day.
Their diet is carnivorous consisting of everything that fits into their mouths such as moths, flies, crickets and sometimes even small frogs. Young frogs commonly eat fruit flies and pinhead crickets. Since Red-Eyed Tree Frogs are not venomous, they use their bright colors as a defence mechanism to stun their predators (startle coloration). Seeing as their predators use vision to hunt, once their eyes latch onto their prey, they are often startled by the shockingly bright colors which caused a “ghost image” to be left where the Red-Eyed Tree Frog was originally. This allows the tree frog to make an escape.
Their predators commonly consist of Bats, Snakes, Birds, Owls, Tarantulas, and small Alligators.
