Hairy Frog.Trichobatrachus robustus.

Experts have named this frog with a curious name, "Hairy frog". That's rare to see these two together, hair in an amphibian skin. Possibly the only frog that has hair, but also the only amphibian in the world, so it makes an animal very peculiar.

But this name has trick: the hair is really skin. Apparently, it seems hair are really thin skin that help to breathe. As almost all amphibians, the hairy frog breathes by small lungs and through the skin. Well, thanks to these hairs skin, fine capillaries are able to pick up a needed oxygen.

But the frog's hair is not the only peculiarity of this animal ... has many more, eg see two characteristics that make this a frog amphibian particular:

1 °. It is an active hunter, and its prey can find slugs, millipedes, spiders, beetles and grasshoppers. And it has teeth. Let me repeat, is a frog with teeth, W-I-T-H-T-E-E-T-H ... in fact, tadpoles are born with teeth. You imagine a frog with teeth? Can be? Yes :

2 °. The second characteristic is that it has a secret weapon (now will cease to be secret) as it can draw on both to hunt and to defend. When the hairy frog feels threatened, intentionally breaking the bones of the fingers of his legs, which pierce the skin and overlook looking like claws. Bone is a hairy frog with retractable claws and teeth ... is rare, rare.

Well, the hairy frog is native to central Africa is robust and is about 11 cm, and it is not considered endangered

The most beautiful bird in the world: The Mandarin Duck.

For its small size, you would make an entry beginning with a phrase ironic about the story of "The Ugly Duckling". But hey, the literature is not my specialty. What I like, is to appreciate the wonderful things created nature, and unlike the Marabou bird that is considered the most "ugly" in the world, the Mandarin Duck (Aix galericulata) the bird is considered "beautiful" in the world.

During the breeding season, the male Mandarin duck loses its brown like the female and looks fascinating and endless color shades in between: The male bird is unmistakable: It has a red bill, large white crescent above the eye and reddish face and "whiskers". The breast is purple with two vertical white bars, and the flanks ruddy, with two orange "sails" at the back. The female is similar to female Wood Duck, with a white eye-ring and stripe running back from the eye, but is paler below, has a small white flank stripe, and a pale tip to its bill.

The beauty of these ducks was originally its curse and then its jacket. For hundreds of years, this bird was considered as a bird that attracting luck and love. And their presence was much coveted by courtesans of Japan and China and collectors from around the world. Currently, some 65,000 live in the wild, several more in zoos and parks all over the world. Its beauty, its colors, have been since the identity and the argument for its protection and recovery. Now, there is no danger of extinction.

The mandarin duck does not exceed 45 cm (17") in length, is small and sturdy, weighing no more than 1,1 lb (500 grams) and feeds on algae and seeds. In winter they are clustered in small groups and as spring approaches the female chooses the male more attractive and colorful to have their "ugly ducklings".
