In humans, the hands are a very important part of the body. We use them for almost everything, and the thumbs are an exceptional evolutionary trait of primates. But agility inherent not only in our species. National Geographic Reviewed animals with the most unusual limbs that give them special opportunities, like people’s hands. Ay ay no other animal cannot show middle fingers, like ay-ay from Madagascar. By compared with the limbs of other primates, perhaps the strangest and disgusting – have ay-ay with his long, bony, clawed fingers, like Nosferatu, and especially the long middle fingers. 
A photo from open sources Ai-Ai uses the middle finger to knock on trees and find cavities in the bark where they can hide tasty insects. Having found such a place, the animal gnaws at a tree and long finger grabs the prey. Though ah bear death only for unfortunately, some people in Madagascar believe that these animals are harbingers of the death of a loved one or demons. “If ah-ah they see near the village, he should be killed, but even then the only salvation from the demon may be the burning of the whole villages, “writes Hilary Bradt in the Bradt Travel Guide Guide about Madagascar. Elena’s Flying Frog Biologist Jody Rowley, an amphibian specialist at the Australian Museum in Sydney, in 2009 discovered an animal, now known as a “flying frog Helena “, on a log in floodplain forests near large the Vietnamese city of Ho Chi Minh City.

Wallace, which is capable of flying up to 50 feet (15 meters), moving from branch to branch in the jungle of Malaysian Borneo. Rowley named a frog in honor of her mother in recognition of support. Any mom would like such a cute gesture. Moles Moles are adorable (with the exception, perhaps, of a stargazer). Paws moles are rather strange – perhaps because they are simply created for digging. These large flat forepaws are used as shovels, and long nails turned out to dig underground burrow in search of shelter and food. 
Photo from open sources In a 2011 report at the University Zurich scientists have proposed one of the reasons why these paws great for digging: moles are multi-toed creatures, and they there is an extra finger. In a starfish, it is a crescent finger. This the extra finger has no moving joints and the mole rests on him while digging; so the spade-like paw gets additional features. The study showed that the embryo mole this bone develops later than the rest of the wrist bone. Gecko Geckos can stick to everything thanks to the lines on legs covered with bristle hairs, which, in turn, covered with even smaller threads (septulae). These threads are so small that they provide the gecko with almost full contact with the surface on which it is located.

That’s why geckos cling to everything like annoying exes. Stickiness of this spider-man inspired scientists to some incredible scientific research. Canadian engineers and scientists from European the space agency created an adhesive coating similar to which the gecko has, allowing robots to stick to the surface spacecraft for its inspection or repair. Inspired by a gecko professor at the Massachusetts Technological Institute Jeff Karp and Robert Langer, Founders of Gecko Biomedical, along with Pedro del Nido from the Children’s Hospital in Boston developed a sticky patch and surgical glue. Both innovations will make the healing of incisions more effective than with classic seams. Goacin U goatsin birds from south america the claws are located in an unusual but very useful place. Goacin chicks are the only birds in which have claws on the wings (when they grow older, they lose them). it real fingers – bent, equipped with solid claws, and one of them is even opposed to the “brush”, which gives the chicks the ability to grab onto branches.

Photos from open sources A similar feature (distinguishing goatsin from other birds, with the exception of African turaco, chicks which are also born with one free finger) makes recall one of the hypotheses that birds evolved from arboreal reptiles, that is, they inherited their an amazing feature directly from reptilian ancestors, separating from the common trunk of birds very early.
However, most likely, everything was different. When forming birds the genes that provide the development of the fingers have not disappeared – they persist in the genomes of all birds, but lose activity in the early stages of embryo development, long before hatching.
Goacins, in their lifestyle, turned out to be profitable again incorporate an ancient forelimb development program by supplying their chicks an additional device for salvation. However, climbing branches is not the only talent of chicks goacin. If the predator still catches up (or if the pivot points were chosen incorrectly), the chick flops into the water … and confidently swims to the shore, sometimes for a long time completely hiding under water, and getting out on land, scrambles on a native tree to get a serving of food from parents.
