Introduction

 
    Elephants are larger mammals in the world. All elephants have several distinctive features. They have no nose but they have trunk. Elephants are herbivores and can be found in different habitats like grass-lands and jungle. The word elephant is based on Latin elephants which is the latin form of greeks. Elephants are very big animal so, they are powerful animal on the land.
 
 
 

Body Organs of Elephant –

 

1. Elephant Trunk

    Elephant trunks have multiple functions, including breathing, touching, olfaction, sound production, and grasping as well as water drinking. The animal’s sense of smell may be four times as sensitive as that of a bloodhound in the Elephants. The trunk’s ability to make powerful twisting and coiling movements allows it to collect food, to kill his prey, wrestle with other elephants, and lift up to 350 kilogram . It can be used for delicate tasks, such as capable of cracking a peanut shell without breaking the seed. With its trunk, an elephant can reach items at height up to 7 to 8 meters and dig for water under sand or mud. Individuals may show lateral preference when grasping with their trunks, someone prefer to twist them to the left and another to right. Elephants can suck up water through the trunk both to drink as well as to spray on their bodies. An adult Asian elephant is capable of holding 8.5 to 10 Liter of water in its trunk.

 

 

 2. Teeths

    Elephants usually have 26 teeth; known as the tusks, 12 deciduous premolars teeth, and 12 molar teeth. Unlike most mammals, which baby teeth or milk teeth and then replace them with a single permanent set of adult teeth, elephants are poly-phyodont that have cycles of tooth rotation throughout all their lives. The chewing teeth are replaced six times in a typical elephant’s throughout whole lifetime. Instead, new teeth grow in at the back of the mouth and move forward to push out the old one. The first chewing tooth on each side of the jaw falls out when the elephant is 2 to 3 years old. The second set of chewing teeth falls out at 4 to 6 years old. The third set falls out at ninth to 15th years of age, and set four lasts until 18th to 28th years of age of whole life. The 5th set of teeth falls out at the early 40th years old. The 6th set must last the elephant the rest of its life.

 

    
 
 
 

3. Bones

Elephant bones are made up of 326-351 bones. The vertebrae are connected by strong joints, which reduce spinal flexibility. African elephants have 21 pairs, while Asian elephants have 19 or 20 pairs.

 

4. Ears

    Elephant ears have thick bases with small tips. The ears, or pins, contain many blood vessels called capillaries. Warm blood flows into the capillaries, helping to release excess body heat from the environment. This occurs when the pinnae are still present, and the animal can magnify the effect by striking them. Larger areas of the ears contain more capillaries, and more heat can be released. Of all the elephants, the African jungle elephants live in the tropics, and they have the largest ears. Elephants are sensitive to low frequencies and are sensitive to 1 kHz (close to Soprano C).

 

Internal organs

 

Brain – The brain of an elephant weight is approx. 4.5 kg to 5.5 kg compared to 1.6 kg for a human brain.

Heart – The heart of an elephant weighs 12 kg to 21 kg . In addition, the ventricle separate near the top of the heart, a trait they share with sirenians.

Testes – A male elephant’s testes are located internally nearly bottom to the kidneys. The elephant’s male organ can reach a length of approx. 100 to 105 centimeter and a diameter of 16 to 18 centimeter at the base. The female has a well developed male gonads at up to 40 to 42 centimeter .

 

Communication system between them

    Touching is an important form of communication among elephants. Individuals greet each other by stroking or wrapping their trunks; the latter also occurs during mild competition. Older elephants use trunk-slaps, kicks, and shoves to discipline younger ones. Individuals of any age and sex will touch each other’s mouths, temporal glands, and genitals, particularly during meetings or when excited. This allows individuals to pick up chemical cues. Touching is especially important for mother–calf communication. When moving, elephant mothers will touch their calves with their trunks or feet when side-by-side or with their tails if the calf is behind them. If a calf wants to rest, it will press against its mother’s front legs and when it wants to suckle, it will touch her breast or leg.
 
    Visual displays mostly occur in agonistic situations. Elephants will try to appear more threatening by raising their heads and spreading their ears. They may add to the display by shaking their heads and snapping their ears, as well as throwing dust and vegetation. They are usually bluffing when performing these actions. Excited elephants may raise their trunks. Submissive ones will lower their heads and trunks, as well as flatten their ears against their necks, while those that accept a challenge will position their ears in a V shape.

 

Intelligence in Elephants

    Scientists debate the extent to which elephants feel emotion ; hence, elephants have highly Intelligent animal on the ground. As with Chimpazis and Dolphins, a dying or dead elephant may elicit attention and aid from others, including those from other groups.
