Beautiful Tree Nymphs: Dazzling Red-Eyed Tree Frogs (16 PICS)

April 15th, 2011 Permalink

Although science fiction has not yet made a B-Grade cheesy movie where glowing red-eyed tree frogs become attacking vampire frogs, these stunningly colored frogs are famous for their ruby red peepers. Scientists believe the red-eyed tree frog developed its vivid scarlet eyes to shock predators and escape from being the prey in that instant of pause. Red-eyed tree frogs are iconic rain-forest amphibians and are often photographed for magazines to promote the cause of saving the world’s rain forests. [16 Photos]

Red Eyed Treefrogs

Red-eyed tree frogs are iconic rain-forest amphibians. They sleep during the day, hidden away, and stuck to the bottom of a leafs, keeping eyes closed and legs tucked in to cover body markings. This makes the little frogs almost invisible to other creatures that might be hunting for prey. There are scientists who believe these flamboyant frogs developed vivid ruby red eyes to shock predators for moment. That pause by predators can give the red-eyed tree a frog a chance to get away.

Leaf's Eye View - Red Eye Frog

Leaf’s Eye View of the red-eyed frog, taken at the Houston Museum of Natural Science Tree Frog exhibit. Although there are many variations in coloring, red-eyed tree frogs use more than their eyes to shock predators. They flash their bulging scarlet peepers at the same time as revealing their webbed orange feet and bright blue-and-yellow flanks. This technique is called startle coloration; it may shock a snake or a bird for an instant, giving the frog a second to spring away to safety. Photo #2 by Adam Baker


Red-eyed Tree Frog (Agalychnis callidryas), photographed near Playa Jaco in Costa Rica

A female red-eyed tree frog will lay her eggs on a leaf which hangs over water. When the eggs start to hatch, the tadpoles start twisting around. All that activity helps to completely break open each egg to release tiny tadpoles. The moisture from the hatched eggs help wash the tadpoles off the leaf to fall into the water beneath them. After the tadpoles metamorphose into froglets, they climb out of the water onto the nearby tree.

The Red-eyed Tree Frog (Litoria chloris) found in eastern Australia

This spectacular red-eyed tree frog was found in eastern Australia. The bright coloring is not a sign of being poisonous, but they are carnivores and chow down on insects. Botanists and other scientists hypothesize that the bright coloring may also function to send sexual signals, but that theory has not been proven. Photo #6 by LiquidGhoul

But it is the red-eyed tree frog’s stunning colors which make it one of the most commonly used frogs in magazine and television advertisements. Photo #14 by Hans Hillewaert
