The Axolotl remains in its larval form throughout its life. This means that it retains its gills and fins, and it doesn't develop the protruding eyes, eyelids and characteristics of other adult salamanders. It grows much larger than a normal larval salamander, and it reaches sexual maturity in this larval stage.

Axolotl is has amazing healing and regeneration abilities. The axolotl is fully capable of complete limb re-growth.

Scientists think is a deep sea anglerfish. Anglerfish are named for their characteristic mode of predation, wherein a fleshy growth from the fish's head acts as a lure; this is considered analogous to angling.

This tube-nosed fruit bat—which became a Web sensation as "Yoda bat"—is just one of the roughly 200 species encountered during two scientific expeditions to Papua New Guinea in 2009, scientists announced in October.Though seen on previous expeditions, the bat has yet to be formally documented as a new species, or even named. Like other fruit bats, though, it disperses seeds from the fruit in its diet, perhaps making the flying mammal crucial to its tropical rain forest ecosystem.

What's more, the newfound Leiolepis ngovantrii is no run-of-the-mill (ordinary) reptile—the all-female species reproduces via cloning, without the need for male lizards.

Initially, this new species—with bristle-based "paddles" for swimming and tentacles on its head—so perplexed Census of Marine Life researchers that they threw in the towel and simply called it squidworm.Found via remotely operated vehicle about 1.7 miles (2.8 kilometers) under the Celebes Sea in 2007, the ten-centimeter-long creature turned out to be the first member of a new family in the Polychaeta class of segmented worms.

Pink HandfishUsing its fins to walk, rather than swim, along the ocean floor, the pink handfish is one of nine newly named species described in a scientific review of the handfish family released in May.

Only four specimens of the elusive four-inch (ten-centimeter) pink handfish have ever been found, and all of those were collected from areas around the city of Hobart, on the Australian island of Tasmania.

In its life cycle, an adult flounder has two eyes situated on one side of its head, where at hatching one eye is located on each side of its brain. One eye migrates to the other side of the body as a process of metamorphosis as it grows from larval to juvenile stage.

As an adult, a flounder camouflages itself by lying on the bottom of the ocean floor as protection against predators. As a result, the eyes are then on the side which faces up.

Gastric Brooding FrogA type of gastric brooding frog, the likely extinct Rheobatrachus vitellinus had—or has—a unique mode of reproduction: Females swallowed their eggs, raised tadpoles in their stomachs, and then gave birth to froglets through their mouths (pictured above).Last seen in 1985, the Australian frog is one of the ten species that conservationists most hope to find during a first ever global search for lost amphibian species.In addition to massive habitat loss, amphibians have declined rapidly due to the spread of the usually fatal chytrid fungus.
