Teeth that never stop growing
|
view preview
Rodents are mammals characterized by a pair of broad, sharp-edged, chisel-like incisor teeth that are firmly inserted in both jaws and are used in gnawing vegetation. The front surface of each incisor tooth is composed of enamel, and the hind surface is of soft dentine wears away during the process of gnawing so that the teeth are constantly kept sharp. Shown above is a beaver sporting bright orange teeth; the reason they are orange is because of an unusually high concentration of iron in the enamel. Unlike human teeth, the incisors of rodents don't have roots, and they never stop growing! To keep these teeth from growing into their brains, rodents grind their teeth against each other. This friction is similar to using a grindstone to sharp ...

Leafy Seadragon
|
view preview
This is the spectacular Leafy Seadragon. Its dangling skin disguises the vulnerable species as floating seaweed. Like seahorses, the male Leafy Seadragon carries the eggs, which are bright pink when the female first deposits them, but turn purple or orange when they're ready to hatch after nine weeks.

Ever seen a potoo?

view preview
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.

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. ...

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.

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.

Global warming, a cause for hunger
|
view preview
A lack of sea ice caused by global warming meant this polar bear was unable to hunt seals and died of starvation. The carcass was found in northern Svalbard, Norway, far from its normal range, where he probably was looking for food.
