It turns out, those infamous teeth are in fact razor-sharp modified placoid scales. Doesn't quite have the same ring to it.

Zonkey?
|
view preview
This is Ippo, a three-month-old Italian zonkey. She is the result of a union between a male zebra and a female Amiata donkey, which is an endangered breed of donkey native to southern Tuscany. Genetic differences between the zebra and the donkey - donkeys have 62 chromosomes and zebras have between 32 and 46 - mean that hybrids like this are most often the result of a male zebra pairing with a female donkey. So far there have only been three recorded cases of a male donkey siring a zebra hybrid. ...

How to stand out in Australia
|
view preview
A 2-year-old albino kangaroo has been spotted in Canberra’s Namadgi National Park. Albino kangaroos in the wild usually don’t survive because they stand out and become an easy target for predators. Albino animals also have a genetic predisposition towards sight and hearing issues, making life in the wild almost impossible—but Rene(e), which is always surrounded by its mob, has survived against all odds.

Imagine staying in flight for six months straight
|
view preview
New data shows alpine swift can spend up to 200 days in the air. It is a mystery how the birds are able to physiologically accomplish this feat. While their diet is relatively straightforward, they feed on airborne insects, how they rest in midair is not known.

Long middle finger
|
view preview
The aye-aye lives in the forests of Madagascar. Despite looking like a very scared rodent, the aye-aye is a kind of lemur with a bushy tail and super-thin, elongated middle fingers that they use to dig grubs out of hollow branches. Aye-ayes also have huge lower incisors to chew through wood and bamboo—and in captivity they’ve been known to chew through concrete cinder blocks ...

You big fat 'sea' pig!
|
view preview
Sea pigs are marine animals around 15 cm long that live about 1,000 metres down on the deep sea floor. They are scotoplanes (sea cucumbers) and their 'legs' are actually elongated feet which are used to push food into their mouths. The apparent antennae on the front of the head are also feet, used to tread the deep sea water. They feed on deep ocean mud and thrive on the organic material present there. The sea pigs are not considered as a threat to humans and they are not an endangered species. ...

One colourful duck
|
view preview
The Mandarin duck is a sexually dimorphic species, meaning males and females differ in appearance. The male has a rich, colorful appearance, which includes brown cheeks and a long brown and white crown sweeping back from the top of the head. The chest is dark purple, with black and white strips, and the wings are brown with an iridescent blue-green edge. This striking coloration helps the male attract the less-colorful females, which display brownish-black plumage with white markings around the eyes and along the throat. ...

Potoos are a small New World family of solitary and nocturnal birds. Most are so poorly known they seem more fiction than substance, their gruff or wailing cries ghostly delusions of the dim nocturnal world they inhabit.

A parrot with a wicked hairstyle
|
view preview
This is a Palm Cockatoo, also know as the Goliath Cockatoo. Palms are distinguished by their size, huge beak (second only to the Hyacinth Macaw among psittacines and largest proportionate to size), solid black feather coloration, large open crest, bare red cheeks, and red and black tongue. You have to see their tongues to believe the coloration. It's amazing. Palm Cockatoos are severely threatened. They are CITES Appendix I birds and are protected in Australia. As a testament to their rarity, typical prices in the U.S. for Aterrimus Palms are around $8000 and Goliaths around $14,000. Perhaps contributing to their rarity is the fact that, according to both Low and Forshaw, they lay only one egg per clutch. ...

Bunnies that glow in the dark
|
view preview
Glow-in-the-dark rabbits were born a few days ago at the University of Istanbul, Turkey. To produce the ‘mutant’ bunnies, researchers took two embryos from a pregnant female rabbit, injected them with a fluorescent jellyfish protein, and reinserted them into the female rabbit. The scientists believe this experiment could help in the development of better, more efficient ways to produce medicines.
