Albino Axolotl

Axolotls are neotenic – meaning they remain in their larval, gill-breathing form and usually do not metamorphose into lunged, land-living adult salamanders. Axolotls can assume various forms including Golden, Leucistic and Albino. The leucistic (white) form displays the dark eyes that many pet owners find more appealing than the blood red blinkers of the albino variety. Here’s a short video of a “dancing” axolotl complete with cute/annoying background music

Albino Koala

Onya-Birri, the only albino koala in captivity, was born September 1, 1997 at the San Diego Zoo. He spent the first six months of his life the way all baby koalas do – inside his mother Banjeeri’s pouch. When he emerged for the first time, zoo staff were likely as surprised as Banjeeri though she has raised Onya-Birri just as she would a non-albinistic cub.

The penguin with glowing yellow eyes

The yellow-eyed penguin, also native to New Zealand, is the rarest and strangest penguin in the world. It can dive to an astounding depth of 400 feet, likes to feed 20 miles from shore, and prefers to nest in the forest rather than on the beach. Penguin families tend to keep to themselves rather than congregate as most penguins do. Because of shoreline deforestation, these unusual-looking penguins are at great risk.

Aye Aye

Sharing something in common with bats, aye ayes are the only primates of the mammal world to rely on echolocation for hunting. The aye aye is a rather unusual cousin of us humans. It lives in spherical nests with a small hole for entry and exit. It uses its long, slender middle finger to tap on trees in order to find tasty insects – and it uses this same finger to scoop them out. Perhaps it is due to its unusually-large eyes and ears that this unique, sensitive primate is believed to be a demon or a bad luck omen. A native of Madagascar, it is often killed at first notice by the island’s superstitious residents.

Kakapo

This is not only the rarest, but the strangest parrot in the world. Imagine a rather portly nocturnal bird that never flies, preferring to hike through hilly forest for miles every night. It weighs in as the heaviest parrot in the world at 8 pounds. Imagine this and you have the very real (but virtually extinct) kakapo. A resident of New Zealand, which is home to a number of rare birds, there are only 62 kakapos remaining on earth. (Bonus fact: New Zealand is full of unusual creatures. It originally had no native land mammals, so its many unique birds evolved in unusual ways – which unfortunately has made them very vulnerable to mammals that were brought in during European colonization.)

Diving with predators

Hold that pose: Sperm whales are the largest living predator on the planet

Diving to depths of three kilometres to feed on giant and colossal squid also makes them the deepest diving mammal.

The clicking sound they make is also the loudest sound made by any animal.

Male whales can grow up to 20.5 metres or 67 feet long and can weigh up to 57,000 kilos.

Cat Sprouts Wings

It's said that every time you hear a bell ring, a cat gets its wings. Oh wait, that's angels. Well, either way, some cats have wings, or wing like protrusions growing from their backs.
In Quingyan province in China, a tabby cat named Tom recently grew its own pair of fur-covered wings. According to the U.K.'s Daily Mail, the wings started as odd growths on the cat's back, they later turned into what looked like wings during a hot spell in China.
The cat's owner, Feng, told the Daily Mail that the wings were stress induced, caused by females harassing the cat to mate.
But genetic experts say the growths are not actually wings. Instead, they are a result of poor grooming, a genetic defect or a hereditary skin condition.
Still, the wing like protrusions do contain bones, but, considering that they're not actually wings, it's not likely the cat will ever gain the ability to fly.
