For this animal is not a form of camouflage but also a mode of communication. By changing the appearance of their skin , they indicate their mood to their peers . For example, Jackson Chameleon ( Chamaeleo jacksonii ) is covered with yellow spots when angry and Mont Lefo Chameleon ( Chamaeleo wiedersheimi ) will turn gray if he is afraid . Stress, courtship , illness, pregnancy, submission ... each color its meaning !

 Please note that this capacity is not unlimited, however ! Indeed, each species has only one range of colors due to its privileged environment . This is why researchers can use the dresses chameleons to identify them. While land chameleons color variations of brown , tree species will decline rather ranges of green, yellow or blue.

 Elsewhere on the planet , many other animals use this communication technique . This is particularly the case of the cuttlefish that can not only change color in seconds but also change the texture of his skin !

Why Do Ducks Have Orange Feet?

Actually, many species of ducks have feet and legs! tinted a bluish green or gray. But for the ducks that do have orange feet, well, it's all about attracting the ladies. Chicks dig orange. Kevin Omland is an evolutionary biologist at the University of Maryland at Baltimore County, and he knows as much about mallard-duck coloring patterns as anyone; it was his graduate thesis. "I looked at male mallards and thought, gosh, they exhibit so many wonderful colors, I wonder which ones females care about," he says. Do lady ducks lust after the males' green head plumage? Or maybe it's the blue patches on the males' wings? Then again, what female duck can resist a nicely proportioned set of white "neck tie" feathers? After four years of documenting mallard courtships, Omland found that none of those mattered. All they cared about was the brightness of the guy's yellow-orange bill. Bright orange coloring suggests that a male duck, also known as a ...

Poison Dart Frog Facts

By 24 Hours Of Culture -

Poison dart frogs, members of the Dendrobatidae family, wear some of the most brilliant and beautiful colors on Earth. Depending on individual habitats, which extend from the tropical forests of Costa Rica to Brazil, their coloring can be yellow, gold, copper, red, green, blue, or black. Their elaborate designs and hues are deliberately ostentatious to ward off potential predators, a tactic called aposematic coloration. Some species display unusual parenting habits, including carrying both eggs and tadpoles on their backs. Although this "backpacking" is not unique among amphibians, male poison arrow frogs are exceptional in their care, attending to the clutch, sometimes exclusively, and performing vital transportation duties. Dendrobatids include some of the most toxic animals on Earth. The two-inch-long (five-centimeter-long) golden poison dart frog has enough venom to kill 10 grown men. Indigenous Emberá people of Colombia have used its powerful venom for centuri...
