Agalychnis callidryas, the red-eyed tree frog, is a slender, colorful, medium-sized frog. Females measure up to 77 mm, and males to 59 mm (Savage 2002). Agalychnis callidryas is nocturnally active. This frog is arboreal and shelters on the underside of a broad leaf during the day and during the dry season, with limbs folded underneath its body (Leenders 2001). It has also been found in bromeliads, though this appears to be rare (Duellman 2001). Physical Description. Agalychnis callidryas are known foremost for their huge, bright red eyes, a possible adaption to nocturnality or the central component of a defensive strategy called startle coloration. Their dorsal area is usually a neon-like shade of green, but can sometimes range from blue to yellow in coloring.  The red-eyed tree frog (Agalychnis callidryas) is an arboreal hylid native to Neotropical rainforests where it ranges from Mexico, through Central America, to Colombia. It is sometimes kept in captivity. The scientific name of red-eyed tree frog, Agalychnis callidryas, comes from Greek words kallos (beautiful) and Dryas (a tree or wood nymph). As its name suggests, the red-eyed tree frog has red eyes with vertically narrowed pupils. It has a vibrant green body with yellow and blue vertically striped sides By Laura Klappenbach. The red-eyed tree frog (Agalychnis callidryas) is a vibrantly colored frog with large red eyes, a green body and light blue sides with yellow strips. Its feet are bright orange and its legs are mostly green. The underside of the red-eyed treefrog is a light-cream color. Young red-eyed tree frogs are brown and gain their distinct coloration as they mature. Adult red-eyed tree frogs can temporarily change their color to a darker green or reddish brown color. The red-eyed tree frog has a delicate build. Share. By Laura Klappenbach. The red-eyed tree frog (Agalychnis callidryas) is a vibrantly colored frog with large red eyes, a green body and light blue sides with yellow strips.

Young red-eyed tree frogs are brown and gain their distinct coloration as they mature. Adult red-eyed tree frogs can temporarily change their color to a darker green or reddish brown color. The red-eyed tree frog has a delicate build. Agalychnis callidryas has a rounded head and a truncated snout when viewed from above (Duellman 2001). Eyes are large and directed sideways (Leenders 2001). When this frog closes its eyes, transparent lower eyelids marked with a network of gold are apparent (Leenders 2001). It has distinct tympana (Savage 2002). Agalychnis callidryas is nocturnally active. This frog is arboreal and shelters on the underside of a broad leaf during the day and during the dry season, with limbs folded underneath its body (Leenders 2001). It has also been found in bromeliads, though this appears to be rar The Red Eyed tree frog exhibits a brilliant display of colors with it's emerald green head and back, sky blue inner legs, creamy white to yellow and bright blue striped sides, orange toes, and, of course, those piercing red eyes. Their color and size vary depending upon their geographic origination. The Red Eyed tree frog species was named, and quite perfectly so, by Cope in 1862 as Agalychnis callidryas. Agalychnis represents their genus and callidryas is derived from the greek words kallos, meaning beautiful, and dryas meaning tree nymph hence the ever appropriate name: the beautiful tree nymph Facts about this animal. It is a medium-sized tree frog, ranging from 5 cm to 7.5 cm. it is arboreal and completely nocturnal. The most apparent physical feature is their red eyes. The dorsal side and legs are usually bright lime green, and the sides of their body are striped in blue and yellow. The musical mating ritual of the red-eyed tree frog is begun by the loud croaking of one male, who is quickly joined by other ones in the area, all sharing the common goal of attracting females. This loud croaking continues as A. callidryas males jump from one leaf to another in a crazed attempt to establish territory.
