A zoo where people are caged and animals roam free!

"Rather than having to photograph from behind wire fences, [I hope to] capture images of animals such as lions in the wild, free and unrestrained," writes Greg Van Dugteren of this image taken at New Zealand's Orana Wildlife Park.

This beautiful white coat serves as a perfect camouflage
|
view preview
The arctic fox is an incredibly hardy animal that can survive frigid Arctic temperatures as low as –58°F (-50°C) in the treeless lands where it makes its home. It has furry soles, short ears, and a short muzzle - all-important adaptations to the chilly clime. Arctic foxes live in burrows, and in a blizzard they may tunnel into the snow to create shelter. Arctic foxes have beautiful white (sometimes blue-gray) coats that act as very effective winter camouflage. The natural hues allow the animal to blend into the tundra's ubiquitous snow and ice. When the seasons change, the fox's coat turns as well, adopting a brown or gray appearance that provides cover among the summer tundra's rocks and plants.

Ever seen a black flamingo?
|
view preview
On the Mediterranean island of Cyprus, you might be lucky to find a black flamingo. Normal flamingoes are born white and grey, and turn their iconic shade of pinky orange around the age of two, as a result of the high carotenoid content of the algae and crustaceans that they eat. Experts believe that this individual (and potentially the other bird spotted in Israel) has a genetic condition that causes it to overproduce melanin, changing its feathers to black.

Walking sushi
|
view preview
While this may look like sushi, it's actually Argentina's pink fairy armadillo. This rarely seen animal has silky white hair and a pinkish carapace; it ranges in size from 3.3 to 4.6 inches (84 to 117 millimeters) long, making it one of the smallest species of armadillos. The animal is also nocturnal and has the ability to bury itself in lightning speed given its long claws, which are an astonishing one-sixth the length of the body. ...

Tails designed to fool
|
view preview
The green wings of luna moths, with their elegant, long tails, aren't just about style. New research finds they also help save the insects from becoming bat snacks by creating a distracting acoustic signal, which causes these predators to zero in on the wings rather than more vital body parts.

"Give orange me give eat orange me eat orange give me eat orange give me you."
|
view preview
That's the longest string of words that Nim Chimpsky, a chimpanzee who scientists raised as a human and taught sign language in the 1970s, ever signed. He was the subject of Project Nim, an experiment conducted by cognitive scientists at Columbia University to investigate whether chimps can learn language. After years of exposing Nim to all things human, the researchers concluded that although he did learn to express demands - the desire for an orange, for instance - and knew 125 words, he couldn't fully grasp language, at least as they defined it. Language requires not just vocabulary but also syntax, they argued. "Give orange me," for example, means something different than "give me orange." From a very young age, humans understand that; w ...

How does our vision compare to some animals?
|
view preview
Do animals see the same way we do? Do some animals have better vision than humans? The senses of animals have evolved to give members of the species an optimum chance for survival. Here are a few examples: Some animals, such as cats, have a reflective surface ( tapetum) on the back of the eye behind the sensory receptors (left image above). When light first enters the eye, some light is detected by the sensory receptors. The light not detected by the sensory receptors continues onto the reflective surface at the back of the eye. This light is then reflected outward toward the sensory receptors, providing a second opportunity for detection. This feature produces two results. First, the outward reflection results in the shining of the cat's ey ...

Wombats have cube-shaped poop

Wombat droppings are cube-shaped. This prevents them from rolling away when marking their territory. These cube-shaped poop looks like, but doesn't taste like chocolate brownies.

Most mammals take 21 seconds to pee, regardless of their size
|
view preview
An elephant takes the same amount of time to empty its huge bladder as a cat - despite holding 3,600 times more urine. That's a whole lot of pressure. The controlling factor of urination duration is the length of the urethra, which gets longer at a predictable ratio as an animal gets bigger. All animals have urethras of the same aspect ratio: a length-to-width ratio of 18. This is rare among animals. Usually, body parts change in relative size, such as the eyes and brain. As the urethra gets longer, the effects of gravity increase and there's more pressure pushing out the urine.
