The greatest mammals who live on land, cannot but cause interest in humans. There are still riddles in the behavior of these animals, the brain of which weighs up to 6 kilograms, and the life of life is average equal to human - 70 years. Matriarchat reigns in the elephant kingdom, the males rarely remain next to the females, the pregnancy of future mothers lasts extraordinarily for a long time, and the kids are raising the "all of the world."
Since the long time, these animals were tamed to use their strength and power, they became participants in great battles and long-term travels. The interest of scientists to these giants caused the ability to recognize themselves in mirror reflection, hear and memorize not only places and events, but also music, take collective decisions. Unlike most animals, elephants are recognized not only by congor, even after a long separation.
They show special feelings and against the dead. Near the remains, they always stop and spend some time, often touch the bone of the skeleton with a trunk's tip, as if identifying the body. There are many interesting and even mysterious facts in the world of elephants.
With a length of 5 to 8 meters, the growth of this animal can reach 3 or more meters, and the weight is 5 to 7 tons. African elephants are larger than their Asian fellow. The massive torso matures an equally huge head with a long trunk - an organ formed by the controversial nose and the upper lip.
It's interesting! This body has a powerful muscle and tendons system, thanks to which animals crawl century-old trees, easily carry from place to the place of the log, but they can cope with almost jewelry work: to raise coins, berries, even draw.
Trunk helps to defend against attacks, extract food, with its help elephants communicate with each other. Touching the foliage from the trees or pulling out young shoots with the root, with the help of a trunk elephant puts food in her mouth, pulling them the water, not only wiping herself, but also pours into the mouth to get drunk. Very large ears are permeated with blood vessels, it helps to reduce the body temperature during a suffocating heat.
Not too good vision of the elephants is compensated by an excellent hearing: for 100 km, animals hear rolling thunder, "feeling" approaching shower. And the ears' constant movements are needed not only to "cool" the body, but also to communicate - the ears of elephants welcome the relatives, and they can be warned from the attack of enemies. Elephants are able to publish and hear infrasounds, communicating among themselves at huge distances.
Thick-skinned these animals are called no coincidence: the thickness of the skin reaches them up to 3 cm. Hard, very wrinkled skin is covered with rare hairs, a small beam is often available at the tip of the tail. Reminded huge foot columns on the feet have a special fat pillow in the downwards directed by fingers, which allows you to evenly distribute weight when walking and running. Most often, the flock of elephants slowly moves in search of food and water at a speed of no more than 6-8 km per hour, but they are capable and run rather quickly, they swim well. There are no elephants only to jump - this is due to the special structure of their feet.
