On Earth, there are many interesting animals, the natural world the fascinating and mysterious.It is very sad to know that many species threatened with extinction and listed in the Red Book.Even sadder to realize that animals suffer, to a greater extent because of the person.White rhinos, too, have experienced the hard way a human "care".Northern White Rhinoceros now needs a kind of artificial regeneration.In the past year, died of old age last male, with only 5 females.Scientists have preserved the seed of the animal and hope that they will be able to achieve the birth of small northern rhinos.To the same fate befell not black and white rhinos, you need to take measures to protect these animals.Let's take a closer look at these major representatives of the animal world, how they look and how they behave in the environment.
White Rhino: description
Elephants are the largest animals in the world, takes pride of white rhino second largest after that huge eared.It's a tremendous land mammals.Adult males typically weigh about 2 tons, the elderly can reach weights up to 5 tons.The body length of about 4 m height at the shoulders up to 2 m. These are giants!
White Rhino differs from the black in the main structure of the upper lip.White tripled so that the feed by plucking grass from the ground, the upper lip have a completely smooth.Black his protruding upper lip grip, pulling a tree branches, leaves and tall grass.
in color this animal there is nothing white, it is believed that it was named so because of the distortion of the Boer word wijde, which means - a wide, British-sounding translated - "white".And began to call in all countries - white rhino.In fact, the animal is a slate-gray color, a little lighter than the black rhino.These two species are very similar, they have 2 horns, the front is very long, the posterior horn is almost not developed.The length of the anterior horn in some cases can reach 1.5 meters. With it, the animal pushes the bush, when fed, and, of course, is a powerful weapon serves as protection from enemies.
animal rhinoceros in nature
rhinos live in small communities, but sometimes there are groups of 15-20 animals.Northern White Rhinoceros behaves in such a family as well as his cousin - white rhino.Usually, only the females collected together with the kids and the grown children, males allowed himself to with great displeasure, as they pose a threat to their young.If the male is guilty, the females gather together and kicked him out of the family, sometimes it comes to the fact that the male is killed by the raging horns "women."They suffer "men" only during the rut, in the rest of the time they are a nuisance and courtship are not accepted.
Northern White Rhino - male is very aggressive, much angrier than black representative of this kind.He does not tolerate rivals fight these huge beasts, in many cases before the death of the loser.Grown children accompanying their mother, are in constant danger when in a group home to a jealous male.Very often kids are killed or maimed because of the bad temper negligent "daddy."
territory in which grazing herd old males labeled "fragrant" labels, spraying grass and bushes in the urine.If the community is in danger from the enemy, the group gets into a defensive circle, heads out.Young people, unable to defend himself, hides in the middle of the circle.At such moments, the whole family, forgetting troubles, acting as one.
Procreation
life in the northern white rhino and white hold many more secrets and mysteries, is still not understood, for example, their reproduction is at half-mast curtain.It's a shame, because their numbers are declining in the world all you need this kind of help, not to lose the final.
ready to breed rhinos around the age of 8-9 years.The courtship period falls on time from July to September.Cub female bears as much as half year results at a time of only one baby.At the end of the day baby is already running for his mother, after seven days of grazing, but in addition to the green food sucks milk throughout the whole year.The female of childbearing age results in offspring every 3 years.
White rhinos.What is left of the world?
now on the planet there are about 10,000 white rhinos.I am glad that this number is much larger than 25 years ago, when the animals were exterminated in large quantities.This cheerful statistics, unfortunately, does not apply to the white northern rhino.On Earth, there are only a few specimens of these giants.It may even be that in the coming years will be officially announced that the northern subspecies of white rhino has disappeared.There was still hope for the work of geneticists, they come to grips with the restoration of a unique subspecies.The effectiveness of their research is still in question.
Human impact on the lives of white rhinos
man put a lot of effort to ensure that these animals are on the verge of extinction.Well, that time came around and made sure that was white rhino in the Red Book.
African tribes, though hunted rhinos, but this is rarely done.Without guns could not bring as much harm as they brought the Europeans with their weapons.In the nineteenth century, hunting of these huge beasts had no control or boundaries. Now rhinos are protected, maintained strict control of their numbers.
