Vietnamese Mossy Frog

Theloderma corticale, or the Vietnamese mossy frog, is a species of frog in the Rhacophoridae family. It is found in Vietnam and possibly China. Its natural habitats are subtropical or tropical moist lowland forests, intermittent freshwater marches, and rocky areas. The common name of the mossy frog arises from the fact that its skin is a mottled green and black that resembles moss growing on rock, and forms an effective form of camouflage.(Link 1 | Link 2)

Chile Darwin's frog

The Chile Darwin's frog was fairly regularly seen until around 1978, since when it seems to have disappeared, and the species may now be extinct. This species, which lives in the leaf litter on the forest floor, has an unusual method of parental care; the male takes the fertilised eggs from the nest into his vocal sac where they hatch into tadpoles after approximately eight days. When he starts to feel the newly hatched tadpoles wriggling, the male carries them to a stream where he expels the young. Here they complete metamorphosis.(Link | Photo)

Ornate Horned Frog

Poison Dart Frog

Poison dart frog, like this sapphire-blue species, is the common name of a group of frogs in the family Dendrobatidae which are native to Central and South America.

 Unlike most frogs, species are active during the day, and often exhibit brightly-colored bodies. Although all dendrobatids are at least somewhat toxic in the wild, levels of toxicity vary considerably from one species to the next, and from one population to another. Many species are critically endangered. These amphibians are often called "dart frogs" due to indigenous Amerindians' use of their toxic secretions to poison the tips of blowdarts.(Link | Photo)

World's Smallest Frog

Generally speaking, higher altitude means larger animals. But the world's smallest known frog species lives high in the Andes Mountains of southern Peru, between 9,925 and 10,466 feet.(Link | Photo)

Malagasy Rainbow Frog

The Malagasy rainbow frog lives in the rocky dry forests of Madagascar's Isalo Massif, where it breeds in shallow temporary pools found in canyons. This species is well adapted to climbing in its rocky surroundings, and can even scale vertical surfaces! When threatened, this frog will inflate itself as a defence mechanism against predators.(Link | Photo)
