Amazing camouflaged animals (2)
Katydid
If you don't immediately see both katydids in this photo, don't feel bad. Their leaflike bodies also help them evade countless birds, frogs, snakes and other predators around the world.
Flounder
As a type of "flatfish," flounder are ideally suited to life on the ocean floor. They huddle up to the seabed, often aided by speckled skin that helps them blend in, such as this pebble-dwelling flounder. That offers safety from predators, but also lets them ambush prey like shrimp, worms and fish larvae.
Egyptian nightjar
Nightjars are small, nocturnal birds found around the world, often called "goatsuckers" due to a myth about stealing goats' milk (they do hang out near goats, but just to eat the insects they attract). Most nightjars nest on the ground, and many have evolved feathers to match — such as this young Egyptian nightjar, seen resting in its desert habitat.
Stick insect
While most animals need a specific backdrop for their camouflage to work, a few are so well-disguised they're incognito almost anywhere. Stick insects are a good example, with twig-like bodies that let them become virtually invisible just by holding still.
Arctic fox
It may seem bland at first glance, but an Arctic fox's ghostly, almost-blue coat is ideal attire on the tundra. Not only does it disappear in snow and defy temperatures as low as 58 below zero, but it also changes colors for summer, letting the fox hide among rocks and plants.
Chameleon
Few animals are as famous for camouflage as chameleons, whose color-changing skills have made them icons of adaptability. But that probably wasn't the reason they evolved the ability — instead, scientists think they mainly change colors to communicate.

Ten Weirdest New Animals of 2010
T. Rex Leech

A new leech king of the jungle, Tyrannobdella rex—or "tyrant leech king"—was discovered in the remote Peruvian Amazon, National Geographic News reported in April.
The up-to-three-inch-long (about seven-centimeter-long) leech has large teeth, like its dinosaur namesake Tyrannosaurus rex. What's more, the newfound critter's "naughty bits are rather small," noted study co-author Mark Siddall, curator of invertebrate zoology at the American Museum of Natural History in New York City.
New Purple Octopus?

This unidentified purple octopus is one of 11 potentially new species found during a July deep-sea expedition off Canada's Atlantic coast.
"Yoda Bat"

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.
Sneezing Snub-Nosed Monkey

A new monkey species in Myanmar is so snub-nosed that rainfall is said to makes it sneeze—but that's apparently the least of its problems, conservationists announced in October.
"Ninja" Slug

Boasting a tail three times the length of its head, the newly described long-tailed slug is found only in the high mountains of the Malaysian part of Borneo, scientists said in April.
Wood-Eating Catfish

The Simpsons Toad

Nosing around for "lost" amphibian species in western Colombia in September, scientists stumbled across three entirely new species—including this beaked toad.
Self-Cloning Lizard

You could call it the surprise du jour: A popular food on Vietnamese menus has turned out to be a lizard previously unknown to science, scientists said in November.
Squid Worm

Squid? Worm? 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, National Geographic News reported in November.
Pink Handfish

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