Elephant and his ears

Elephant and his ears

Large elephant ears are also important for the temperature regulation. The ears of an elephant are made of very thin material stretched over cartilage and a vast network of blood vessels. On hot days, elephants constantly shaking ears, creating a gentle breeze. This air cools the blood vessels on the surface, and the coolest blood then flows through the rest of the animal's body. The blood that enters the animal's ears can be cooled to about 6 degrees Celsius before returning to the body. The differences between the ears of African and Asian elephants can be explained, in part, by their geographical distribution. African elephants are closer to the equator, where the weather is warmer. Therefore, they have bigger ears. Asians live farther north, in cooler climates, and thus have smaller ears.

The ears are also used for intimidation and by males during courtship. If an elephant wants to intimidate a rival or predator, extends the ears look bigger and more imposing. During the time of breeding, the males emit an odor from a gland located between the eyes. Joyce Poole, a well-known researcher on the elephants, proposed the theory that males shake their ears to spread this "elephantine perfume" to great distances

Elephant and his paw

Elephant and his paw

The feet of an elephant are nearly round. African elephants have three nails on each hind foot, and four on each front foot. Indian elephants have four nails on each hind foot and five on each front. Underneath the feet bones there is a gelatinous layer which acts as an air cushion or damper. For this reason, an elephant can stand for long periods of time without tiring. In fact, African elephants rarely lie, except when they are sick or crippled. Indian elephants, in contrast, lie down frequently. Under the elephant's weight the foot swells, but it deflates when the weight is removed. An elephant can sink into the mud, but can pull the legs easily because their feet downsize when raised.

The elephant is a good swimmer, but can not trot, jump or gallop. It has two floors: the walk and a faster while sharing characteristics with the race. When walking, the legs act as pendulums, with the hips and shoulders up and down when the foot is placed on the floor. The faster rate does not correspond to the usual definition of the race because the elephants always have at least one leg is on the ground. Since both hind legs or the front are in the air at the same time, this step is similar to the front and rear legs run at a time.

Walking the normal pace an elephant walking about 3 to 6 km / h but can reach 40 km / h in the race.

elephant tusks

elephant tusks

The tusks of an elephant are the second upper incisors. Tusks grow continuously; the fangs of an average adult grow approximately 15 cm per year. Tusks are used to dig for water, salt or roots; to remove the bark of trees to eat the bark; to dig the tree adansonia to withdraw its pulp; and to move trees and branches when a path is created. Furthermore, they are used to mark the trees to demarcate the territory and occasionally as weapons.

Like humans who are typically handed, elephants are either left or right hand. The dominant attached, called the master prey is generally shorter and more rounded tip because of the use. Both males and females of African elephants have large tusks that can reach over 3 m in length and weigh more than 90 kg. In the Asian species, only the males have large tusks. Asian females have tusks that are either too small or are simply non-existent. Asian males can have tusks as long as African males, but are usually thinner and lighter; the prey registered heaviest ever weighed 39 kg. The prey both species and consists primarily of calcium phosphate in the form of apatite. As a living tissue is relatively soft (compared with other minerals such as rock), and the prey, also called ivory, is appreciated by artists for its esculturabilidade. The elephant ivory demand has been one of the reasons for the dramatic decline of the world's elephant population.

Some extinct relatives of elephants had also trapped in the lower jaw, as Gomphotherium, or only in the lower jaw, as Deinotherium.

elephant trunk

Elephant trunk

The proboscis, or trunk, is a fusion nose and upper lip, elongated and specialized to become the most important and versatile appendage of an elephant. The tip of the proboscis of African elephants are equipped with two protuberances resembling fingers while Asian elephants have only one of these. According to biologists, the elephant's trunk may have about forty thousand individual muscles, which is sensitive enough to pick up a single blade of grass, but at the same time strong enough to rip the branches of a tree. Some sources indicate that the correct number of muscles in the trunk of an elephant is closer to one hundred thousand.

Most herbivorous (plant-eating, such as elephant) have teeth adapted to cut and tear plants. However, with the exception of the very young or infirm, elephants always use their trunks to pluck the food and take it to the mouth. They graze grass or run up the trees to pick up leaves, fruits or whole branches. If the desired food is too high, the elephant wraps his trunk in the trunk or branch and shake until the food is released or, sometimes, simply completely drops the tree.

The trunk is also used for drinking. Elephants suck water through the trunk (up to fourteen liters at a time) and then pour it into the mouth. Elephants also inhale water to dump on the body while bathing. On this layer of water, the animal then dumps dirt and mud to serve as a sunscreen. If anything, the trunk can also serve as a breathing tube.

This appendix is ​​also an important part of social interactions. known elephants-greet wrapping their trunks, like a shake of hands. They also use it while playing, to stroke during the cutting or interactions between mother and children, and shows of force - one raised trunk can be a warning sign or threat, while a fallen trunk can be a sign of submission. Elephants can defend themselves effectively slamming the trunk intruders or grabbing them and throwing them into the air.

The trunk also serves to give the elephant a very keen sense of smell. Raising the trunk in the air and moving it from one side to the other, like a periscope, the elephant can determine the location of friends, enemies or food supplies.

And Asian (Elephas sp .). There are still mammoths (Mammuthus sp.), Now extinct. Until recently, it was believed that there were only two living species of elephants, the African elephant and the Asian Elephant, a smaller species. However, recent DNA studies suggest that there were actually two species of African elephant: Loxodonta africana, the savannah, and Loxodonta cyclotis, who lives in the woods. Elephants are the largest land animals of today, with a mass between 4 to 6 tons and measuring on average four meters high, can lift up to 10,000 kg. Its most distinctive features are the ivory tusks.
