Fauna Fabula: Unreal Animals in the Real World

Glass Frog or Crystal Frog (Hyalinobatrachium pellucidum)

The frog is named for its skin which is translucent to the point that internal organs and surfaces immediately behind the frog can be seen. The reason for this is lack of pigmentation. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist mountains and rivers. It is threatened mostly by habitat loss, although conservation programs have begun to help save this interesting creature.

This frog is about the size of a fingernail.

Turtle Frog (Myobatrachus gouldi)

The Turtle Frog is a fossorial (burrowing) species, and probably the most fossorial of all Australian frogs. They even call and mate underground, where the eggs are laid in the moist sand and develop directly into frogs.

Purple Frog, Pignose Frog or Doughnut Frog (Nasikabatrachus sahyadrensis)

The chubby, seven-centimetre-long, purple amphibian with a pointy snout was found hopping around in the Western Ghats, a range of hills in western India. Its head appears too small for its body and it looks more like a squat, grumpy blob than a living creature. 

Imbabura Treefrog (Hypsiboas picturatus)

Hypsiboas picturatus is a species of frog in the Hylidae family. It is found in Colombia and Ecuador. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.

Surinam Toad (Pipa Pipa)

Surinam toads, also called star-fingered toads, are members of the frog genus Pipa, within the family Pipidae. They are native to northern South America. Like other pipids, these frogs are almost exclusively aquatic. The appearance of the toad is somewhat like a leaf. It is almost completely flat, and colored in a mottled brown. Feet are broadly webbed with the front toes having small, star-like appendages.
