Two ghost frog species, Hewitt's ghost frog (shown) and the Table Mountain ghost frog, made the top-10 list. Both live on southern tip of South Africa. The Table Mountain ghost frog is found in Skeleton Gorge, which is where local people traditionally buried their dead.

The Bornean flat-headed frog (Barbourula kalimantanensis) which is 2.8-inch-long (7 cm) is the world’s first lungless frog. Instead of lungs, the slimy amphibian breathes through its skin. Other organs can be found in the place lungs would normally be, which makes the overall appearance of the frog flatter.The flatter body shape means more surface area relative to volume with which to absorb oxygen. In addition, the squashed shape is more aerodynamic, allowing the frogs to maneuver better in the fast-flowing streams in the Kalimantan rainforest where the species lives.

Dwarf Salamander

A fanged frog discovered in Thailand likely feeds on birds as part of its diet, as scientists have found feathers in the frog's feces.

Called Rhacophorus penanorum, this tiny frog species, whose males grow to just 1.4 inches (3.5 centimeters), was discovered in Gunung Mulu National Park, Sarawak, in the Heart of Borneo. Also called the Mulu flying frog, the amphibian has a small pointed snout and is unusual in that the species has bright green skin at night but changes color to display a brown hue during the day. Its eyes follow suit to change color as well. And while the minute animal may not fly with the birds, it uses its webbed feet and aerodynamic flaps of skin on the arms and legs to glide from tree to tree.

Rainbow Frog
