Frogs of the Rainforest

If someone told you that you could visit a place where there are blue frogs and frogs that could fly, would you believe them? Well you could find frogs just like that if you visited the Rainforest. The diversity of frogs that live in the Rainforest is amazing. Nowhere is there such a wide range of colors, sizes and survival strategies. Horned toads are camouflaged to look like dead leaves, while the brilliant colors of tiny poison arrow frogs advertize that they're toxic. Glass frogs are so transparent that their bone, muscles and internal organs will show right through their skin. An amazing frog found in the Rainforest is the Asian flying frog, if it feels threatened it will escape by gliding away on four parachutes of skin stretched between the toes of each foot.



Tropical rainforest frogs are divided between the cleverly camouflaged and the distinctly gaudy. The vivid crimsons, golds, lime greens and yellows of the rainforests' flashiest amphibians indicate the presence of skin toxins and act as a warning to would be predators. As a defense, it works: birds avoid brightly colored frogs although some snakes are immune to the toxins. Other frogs may only become visible as they move, exposing a bright patch of blue or red under their legs known as a flash color. Again, this is a form of defense mechanism, as the flash color is supposed to startle the predator giving the frog time to escape.





The Poison dart Frog


Poison-dart frogs, such as this Dendrobates pumilio photographed in Costa Rica, derive their name from the fact the toxins they secrete for defense have been used in hunting by indigenous peoples in South America. This species has a fascinating life history in which it carries its eggs from the forest floor high into the canopy where they are placed in the water of a tank bromeliad. After the eggs hatch, the frog provides food for the tadpoles by laying unfertilized eggs in the water. The frog in this photograph is in the process of climbing a tree.
