The Atelopus frog

The Atelopus frog is known by many names such as the clown frog or the Costa Rican Variable Harlequin Toad. Whatever you call the frog, it is a neo-tropical toad that was once quite wide spread living throughout Costa Rica and Panama. The species is listed as critically endangered and is thought to be living primarily in Panama today. Photo: Paul Ouboter / Conservation International. (Link)

The veiled chameleon

The veiled chameleon, Chamaeleo calyptratus, a large and colorful species of chameleon, are found in Yemen and Saudi Arabia and also sometimes referred to as the Yemen Chameleon. This chameleon changes color depending on its mood. The prominence of these markings is dependent on several factors including health, mood, and temperature of the lizard.(Link)

Insects typically do not stand out

Insects typically do not stand out. Something to do with being their one way ticket to certain extinction, generally.

 A fact that just adds to the mystique of the extremely rare pink katydid. What is perhaps strangest about this species is where they are turning up; the majority of pink katydid images are attributed to the most untropical places such as Osaka and the American Midwest. Speculation is that their unusual color is caused by the genetic condition erythrism, which denotes an unusual red pigmentation. (Link)

The flamingo tongue snail

The flamingo tongue snail (cyphoma gibbosumn) is a small, colorful sea snail which lives on various species of soft corals in the Caribbean.

 This creature almost-literally wears its heart (soul and colors) on its sleeve. The pretty color you see in this image is not a snail's shell! Rather, it's in a layer of live mantle tissue, connected to its foot - the snail pushes it out to cover the shell. The mantle tissue also works like a fish's gill. When the snail is attacked, the mantle (and colors) is withdrawn. So you might say, this is the only marine animal that literally turns pale in fright.(Link | Photo)

Mwanza flat-headed agama's vivid blue-and-red colouring

The lizard in the photo is not being manipulated (not a photo manipulation). It is now the latest exotic pet craze. Mwanza flat-headed agama's vivid blue-and-red colouring, is a lizard that has a body skin colour similar to Spiderman. Agamas, which are native to Kenya can be good pets, as they become tame and docile if handled regularly.

It can grow up to a foot long, and a balanced diet for them includes locusts, crickets, meal worms and wax worms. They are unable to throw webs, but can change colour – the brightly coloured males will change brown at night or if frightened. They can also run on their hind legs, and can scale vertical walls like spiders.(Link)

Purple polar bear

Look at this strange animal! Yes, that is a purple polar bear believe it or not! This usually white polar bear created quite the buzz about the Mendoza City Zoo in Argentina when it unexpectedly turned purple. It seems that the polar bear named Pelusa had a skin condition that the zoo officials were trying to treat, and as a result of the special treatment of this condition the polar bear turned purple.

 The purple color only lasted for a little while, but it was quite the talk of the town and spread across the world news and internet like wildfire. (Link)
