When rainfall is at its highest, a male red-eyed treefrog calls 'chack' to get the attention of the female. This is the first evidence that tree-dwelling vertebrates use vibration to communicate. During the mating season, the male frogs shake the branches where they are sitting to improve their chances of finding a mate by keeping rivals at bay. The sudden appearance of the red eyes may startle the predator, giving the frog a chance to flee.Īlthough random mating in Agalychnis callidryas has been documented, studies have shown that an increased body size is an indicator of male quality while looking for a mate. When a red-eyed treefrog detects an approaching predator, it abruptly opens its eyes and stares at the predator. Their large red eyes not only aid in their ability to see at night, but also serve as a defensive adaptation through deimatic behaviour. They do not have a true eyelid, but rather a nictitating membrane that allows light to enter the eye so that they will awaken when predators are approaching. Thus, they appear almost completely green, and well hidden among the foliage. In order to hide from predators, they cover their blue sides with their back legs, tuck their bright feet under their bellies, and shut their red eyes. They are nocturnal, sleeping for most of the day. Despite their bright coloring, red-eyed treefrogs are actually not poisonous, and rely on camouflage to protect themselves. It is possible that color patterns have been affected by different selective pressures, and that the existence of some morphs are due to genetic drift.Phyllomedusine treefrogs are arboreal, meaning they spend a majority of their lives in trees they are excellent jumpers. One strong hypothesis is that the existence of orange and purple morphs in Costa Rica are caused by isolation by distance, because the orange and purple morphs were not genetically distinct groups. There are several hypotheses for the reason behind the existence of these color morphs.

Red-eyed tree frogs have variation in the color of their side stripes, which in Costa Rica and Panama specifically includes blue, blue/red, orange and purple. Though the main coloring of Agalychnis callidryas is consistent, there are some variations in morphs across the geographical range of the species. Albino Red Eyed Tree Frog Distribution of color morphs Paper towel will need to be changed 2-3 times a week. If using sphagnum moss, make sure to press down the moss so it is flat – this will greatly reduce the risk of impaction. Opinions on substrates vary – we’ve had luck with a full bioactive with FR Tropical Biobedding topped with sphagnum moss. Choose a large enclosure – an 18x18x24 Exo Terra Glass Terrarium is a good size for 2-4 juveniles or adults. Recommended Terrarium Size: Red-Eyed Tree Frogs are easy to house. These Albino Red-Eyed tree frogs are completely yellow with bright red eyes. The Red-Eyed tree frog is also known as the Red-Eyed leaf frog. This refers to their sparkling eyes, beautiful appearance, and arboreal habits. Name: The Albino Red Eyed tree frog has a very obvious common name – it is a tree frog with bright red eyes! Its scientific name is Agalychnis callidryas, which literally translates into (aga) plenty of (lychnos) shining (kallos) beautiful (dryas) tree nymph.
