why do tree frogs have red eyes
These iconic rain-forest amphibians sleep by day stuck to leaf-bottoms with their eyes closed and body markings covered. When disturbed, they flash their bulging red eyes and reveal their huge, webbed orange feet and bright blue-and-yellow flanks. This technique, called startle coloration, may give a bird or snake pause, offering a precious instant for the frog to spring to safety.
Thanks to their big bulging red eyes, it's not hard to recognize red-eyed tree frogs.
This alien-like feature is a defense mechanism called "startle coloration. " When the frog closes its eyes, its green eyelids help it to blend in with the leafy environment.
If the nocturnal frog is approached while asleep during the day, its suddenly open eyes will momentarily paralyze the predator, providing the frog with a few seconds to escape.
However, the frogs' eyes are not their only fashion statement! To match the brilliance of their eyes, these frogs have bright lime green bodies that sometimes feature hints of yellow or blue. According to their mood, red-eyed tree frogs can even become a dark green or reddish-brown color.
They have white bellies and throats but their sides are blue with white borders and vertical white bars. Their feet are bright red or orange. Adept climbers, red-eyed tree frogs have cup-like footpads that enable them to spend their days clinging to leaves in the rainforest canopy, and their nights hunting for insects and smaller frogs.
Male red-eyed tree frogs can grow up to two inches in length and females can grow up to three inches.
