Giraffes - the highest of the existing mammals of the planet.
These animals reach 4 to 6 meters in height and have an unusually beautiful and unique color.
Even in a single stage you will not find two individuals with the same pattern or shade of hair.
Living as giraffes wild open spaces, soand in captivity. The period of life - from 25 to 28 years. The main habitat for them is the African savannah, some species, such as reticulated giraffe, found in Somalia, Kenya and woodlands.
These animals are largely astonishing, beginning with its size and unusual buildings, finishing details, which is not even known to all.
Not only the size, the color and the presence of smallhorns, covered with wool, makes giraffes special. Giraffe sleeps only standing, running speeds up to 50 km / h, and the newborn calf falls from a height of 2 meters.
For example, the language of the giraffe is unique: it is a huge and powerful muscles, reaching up to 45 centimeters in length. Color language is unusual - it is completely blue, sometimes purple.
Language length long giraffe causedpuzzled researchers. The long neck of the animal let him pluck the leaves of acacia - a favorite delicacy in the savannah - even with the top of the tree, so an additional drag on the language of the food did not need to.
However, as it turned out, the language is differentgrasping reflex, just twisting in a spiral in contact with food in the mucosa, it is able to bend around the huge plant safety pins and tearing, keep the juicy leaves just the very tip.
The ability to finely control their own languageoften saves the life of a giraffe in a drought, because the lower leaves and grass are actively feed on low-growing animals, ready to violently defend their right to survive. Giraffe accrue only to those leaves that apart from him no one to get can not.
Features of the structure
Color giraffes is not repeated, it is akin to a print of human fingers.
Blue is the color due to the unusual structurethe animal. Due to the high growth giraffe circulatory system is overloaded, the heart of the mammal an incredibly strong and provides the body the pressure is almost three times higher than that of men. The blood of a giraffe with a very thick, the density of blood cells is twice higher than in humans, in addition to the jugular vein has a special valve that interrupts the flow of blood to maintain a stable pressure in the main artery. Thus, we can conclude that the blood vessels that are in their language, denser and darker than usual, and instead of the reddish mucous turns dark, almost purple.
I must say that the blood of a giraffe, too muchdifferent in appearance from the usual. Due to the high content of red blood cells and reactive oxygen compounds, blood dark, almost maroon. That is why a specific color is not only the language, but also the internal organs of the giant.
