London, England animal organization, has selected 10 unique and endangered amphibians globally. Campaign to protect the forgotten creatures. There are currently about 6,200 amphibian species known and many other undiscovered species.

1. This Malagasy frog has a rainbow color that can inflate itself when in danger. It can also climb on steep cliffs.

2. One of the most bizarre species in the world is Sagalla caecilian , a creature with no tactile tendencies on either side of its head.

3. The giant Chinese salamander, can be up to 1.8 meters long. It evolved independently from other amphibians, from 100 million years before the tyrant dinosaurs.

4. This purple frog was first discovered in 2003, because it is buried under 4 m of land all year round.

5. One of the frogs lives only in the ancient graveyards of the Skeleton Gorge, in Table Mountain, South Africa.

6. Found in Mexico, this rare non-lung salamander breathes through the skin and mouth.

7. This Olm blind salamander has transparent skin and lives on the ground. It hunts by sniffing and electromagnetic induction. Creatures can live without food for 10 years.

8. A close relative of frog Darwin ( Rhinoderma darwinii, pictured above), a Chilean frog Darwin never photographed live and is no longer seen since 1978 - probably now extinct. Frogs protect their children by hiding them in their mouths.
