The Red-Eyed Tree Frog (Agalychnis callidryas) is a type of frog which is found on trees and leaves of the tropical rain forests of Central America. are known as arboreal hylid, which means part of the tree-dwelling frog family.
Red-eyed tree frogs are arboreal that spend most of their life on trees and will require a variety of climbing and hiding structures within their habitat. Red-Eyed Tree Frogs can defy gravity and cling to leaves, sticks, and even glass. The suction cup-like foot pad helps them cling to the underside of leaves. Frogs’ feet are not entirely flat and fit into irregular surfaces very well. These frogs can stick to almost any surface, especially anything moist. They are found in the lowland rainforest and surrounding hills, closer to rivers or such water bodies. They are capable swimmers and visit these areas regularly as they can absorb water through the skin on their belly.
They are known for their bulging red eyes with a vertical pupil, which may result from their nocturnal behavior. They sleep by day, clinging to the bottom of the leaf with closed red eyes and body marking covered. The dorsal area is neon green with yellow or blue vertical markings on it. Their sides are light blue or cream-colored or may have yellow stripes. The upper legs are bright blue and the feet are bright red or orange. The suction toe pads are also the same color. The younger red-eyed tree frog may be brown in color and change color as they mature. The Red-Eyed Tree frog is found to be in the range of 2-3 inches. The female is larger than the male. They can change their body color to darker green or reddish-brown.
Red-eyed tree frogs are insectivores, eating crickets, moths, grasshoppers, flies, and other insects. Sometimes, they eat smaller frogs. Tadpoles mostly eat fruit flies and pinhead crickets. A red-eyed tree frog is an ambush predator which catches its prey using the element of surprise.
Despite intense coloration of the body, the red-eyed tree frog is not poisonous like other brightly-colored species of frogs. Their defense mechanism is startled coloration. These colors, as defense mechanisms, help them to merge in with their surrounding green fauna and flora. If the green camouflage fails and a predator spots a sleeping frog, When disturbed or attacked, they will open and bulge their bright red eyes and reveal their huge webbed orange feet and brightly colored yellow and blue flanks. The predator is often so surprised by these sudden flashes of color that it is momentarily confused and hesitates. The shocking colors of this frog may over-stimulate a predator's eyes, creating a confusing ghost image This will make the predator, pause for a moment giving them enough time to jump to safety.
Snakes are especially important predators of tree frogs. Snakes largely search for prey via chemical cues, rather than visual ones, negating the camouflage protection most tree frogs possess. Additionally, many snakes are accomplished climbers that can ascend trees, as well as tree frogs. Birds typically have excellent eyesight and are capable of finding even the most well-camouflaged tree frogs. Otters, raccoons, and squirrels eat tree frogs. The sharp eyesight and dexterous hands of these two mammals assist in locating and manipulating their amphibian prey. Bat regularly predates upon calling frogs, able to discern edible species from toxic species by call alone. Tadpoles are targeted by dragonflies, fish, and water beetles.
Red-Eyed Tree Frogs usually mate in the rainy season. The mating process starts with croaking and quivering mating rituals. The process for mating is called amplexus, which is common among varied frog species. In this process, the smaller males clasp themselves to the larger females when their eggs reach maturity. The males will inseminate the eggs as the females lay them. This process may take a day or longer. They mate the underside of the leaves, while the female is clinging to the leaves for both of them. The female will enter the water after she lays her clutch with the male still attached to her in order to fill her bladder with water. Water will keep the eggs moist. The eggs are laid on the underside of leaves close to the water. The eggs hatch within a few days of laying. After the eggs hatch, the tadpoles will emerge quickly and swim around the eggs until it ruptures. This is a quick process to let the tadpoles enter the water below.
It takes a red-eyed tree frog one to two years to reach maturity, depending on how much they eat. The frogs usually survive about 5 years in the wild, but can live much longer in captivity.
The species is classified as Least Concern by the IUCN due to its wide distribution and presumed large populations; it is also present in a large number of protected areas throughout its range. Pressures on the red-eyed treefrog include habitat loss through deforestation and some collection for the pet trade.
