Red Eyed Treefrog

The title of the most striking amphibians, in my humble opinion, goes to the red eyed treefrog (Agalychnis callidryas)! With huge red eyes; multiple colors that consist of green, yellow, cream, blue, orange, and a white belly; this frog has all the pretty a person can handle. I have personally cared for these gorgeous frogs and loved everything from their colors to their calls. They would even reciprocate calls, if you got even close to imitating them.

First the Stats…

Scientific Name: Agalychnis callidryas
Type: Amphibians
Diet: Carnivores
Group Name: Army
Average life span: In The Wild: 5 years | In captivity: 15 years
Size: 1.5 to 2.75 in

Now on to the Facts!

1.) Red eyed treefrogs spend most of their time in tall shrubs and smaller trees nearing streams, ponds, and pools of water.

2.) When marking territory, males will shake their perch violently. The vibrations tell other males that the area has already been reserved.

Did you know…?
the red eyed treefrog is sexually dimorphic? The males, as in most frogs and toads, are much smaller than the females. This is because the female has to carry the male on her back during mating or amplexus.

3.) Even though red eyed treefrogs have intense coloration on their body, red-eyed treefrog is not poisonous like other brightly-colored species of frogs and salamanders.

4.) When sleeping, the red eyed tree frog uses a transparent “eyelid” or membrane that covers the eyes which allows them to detect movement, via shadows, and still allows them to sleep and protect their eyes. This “eyelid” is called a nictitating membrane.

5.) Red-eyed treefrogs have sticky pads on their toes, which allows them to stick to branches and leaves.

But wait, there’s more!

6.) Red-eyed treefrogs inhabit areas near rivers and ponds in rainforests and humid lowlands on the Atlantic slopes from southern Veracruz and northern Oaxaca in Mexico, to central Panama and northern Colombia.

7.) Red-eyed treefrogs are insectivores, eating crickets, moths, grasshoppers, flies, and other insects. Yum!

Did you know…?
Like other frogs and toads, red eyed treefrogs use their eyeballs to help swallow food!

8.) These beautiful frogs are nocturnal. (They sleep during the day.)

9.) When the tadpoles of the red eyed treefrog are ready to emerge, they drop from the undersides of the leaves they are stuck to and drop into the water. They do this prematurely in an effort to avoid predators that would look for and eat the eggs.

10.) Natural enemies of adult red eyed treefrogs are snakes, spiders, bats, owls and toucans. Tadpoles are targeted by dragonflies, fish and water beetles.

Critter Man

With over 40 years of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge.I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or air.I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!Let it be said that I have been oft times accused of loving animals more than I love people. I can neither confirm nor deny this.
