Comprehensive DescriptionRead full entry
Agalychnis saltator is a relatively small red-eyed frog, with adult males ranging from 34 to 54 mm and the larger females ranging from 57 to 66 mm. This frog can be identified by its red eyes with vertical pupils, and its orange hands and feet. They have extensive webbing between the fingers and toes and large suction disks at end of each digit (Leenders 2001). The adults are light or dark leaf green with some individuals having one to several raised yellow spots on their dorsal side. The sides of the body and anterior and posterior surface of the thighs are bluish purple. Their iris color can range from orange to tomato red. Their ventral side are cream anteriorly with a yellow or orange tint posteriorly. Other than the size difference between the males and females, males develop a dark or black patch on the inside of the base of the thumb during mating season (Guyer and Donnelly 2005). This species closely resembles Agalychnis callidryas (red-eyed leaf frog) but with some differences. It has a uniform dark blue or purple flanks instead of vertical white, yellow, or cream bars found in the red-eyed leaf frog. Another difference is that Agalychnis saltator changes its color from uniform leaf-green during the day to tan or brown during the night, while the red-eyed leaf frog just change their hue (Leenders 2001).
