Atretochoana eiselti

Atretochoana eiselti is a species of caecilian known only from two preserved specimens until its 2011 discovery in Brazil. 

Biologists discovered six of the unusual-looking creatures - each about a metre long - at the bottom of the river-bed on the Madeira river in Rondonia, in Brazil. It is actually more closely related to salamanders and frogs, but appearance-wise looks more like a snake.

Biologist Julian Tupan, who works for Santo Antonio Energy - the company which constructed the dam - said: ‘Of the six we collected, one died, three were released back into the wild and another two were kept for studies.

‘Despite looking like snakes, they aren’t reptiles and are more closely related to salamanders and frogs.

Mr Tupan added: ‘We think the animal breathes through its skin, and probably feeds on small fish and worms, but there is still nothing proven.

A previously unknown caecilian from India watches over her clutch of eggs in the lab of University of Delhi amphibian biologist Sathyabhama Das Biju.  Biju and his team were surprised to discover that females of this newly named species, Chikila fulleri, remained protectively coiled around their developing offspring for up to three months.  “The mother is guarding the eggs for almost 95 days without eating anything,” Biju said. “Always the mother is with her eggs.”  Such levels of maternal care are rarely seen in amphibians, the study team noted.

Axolotl (Ambystoma mexicanum) - Requested by Anonymous

A neotenic salamander, closely related to the Tiger Salamander. It is also called ajolote (which is also a common name for different types of salamander). The species originates from numerous lakes, such as Lake Xochimilco underlying Mexico City. Axolotls are used extensively in scientific research due to their ability to regenerate limbs. Some have indeed been found restoring the less vital parts of their  brains. They can also readily accept transplants from other individuals,  including eyes and parts of the brain—restoring these alien organs to  full functionality. In some cases, axolotls have been known to repair a  damaged limb as well as regenerating an additional one, ending up with  an extra appendage that makes them attractive to pet owners as a  novelty.
As of 2010, wild axolotls are near extinction due to urbanization in Mexico City and polluted waters.

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.

Caecilians

The caecilians are an order of amphibians that superficially resemble earthworms or snakes.  They mostly live hidden in the ground, which makes them one of the  least known orders of amphibians. All extant caecilians and their  closest fossil relatives are grouped as the clade Apoda. They are mostly distributed in the tropics of South America, Africa, and South Asia. The diet of caecilians is not well-known.

Olm, or Proteus (Proteus anguinus) 

A blind amphibian endemic to the subterranean waters of caves of the Dinaric karst of southern Europe. It lives in the waters that flow underground  through this extensive limestone region including waters of the Soča river basin near Trieste in Italy, through to southern Slovenia, southwestern Croatia, and Herzegovina. It is also occasionally called the “human fish” by locals because of its skin color, similar to that of white people, as well as “cave salamander” or “white salamander.”In Slovenia it is also known by the name močeril, which translates as “the one that burrows into wetness.”

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.
