Elephants:Biggest Useful Animals



Largest and useful animals which lives until now are the elephants. They are being used by the people to help them carry logs and travel people from place to place. It also make an awesome feature in a circus or zoo.


 People from places where elephants are common make use of them by pulling heavy objects. Elephants are not cruel animals they are a friendly and helpful animals.

Elephants are the largest animals now living. The elephant's gestation period is 22 months, the loungest of any land animal. At birth it is common for an elephant calf to weigh 120 kgs. (260 lbs). They typically live for 50 to 70 years, but the oldest recorded elephant lived for 82 years.

Many people hunt and kill elephant because of its tusks. Ussually in mammals tusks are enlarged canine teeth but in elephants they are actually elongated incisors. Tusks are essentially no different from other teeth. A third of the tusk is actually hidden from view, embedded deep into the elephant's head. This part of the tusk is a pulp cavity made up of tissue, blood and nerves. The visible, ivory part of the tusks is made of dentine with an outer layer of enamel.

Elephant ivory is unique which when viewed in cross-section reveals criss-cross lines that forms a series of diamond shapes. Elephants tusk never stop growing so some old bulls display enormous examples. However the average size of the tusks has decreased over the past hundred years because hunting elephants for their ivory has resulted in the 'big tusk gene' becoming increasingly rare.

An elephants' tusks are a blessing and a curse. Blessing because they give an elephants a true majesty that rise them above other animals as well and being of use for various tasks. A curse because man's avarice for ivory has led to the senseless slaughter of hundred of thousands of the magnificient animals.

This helpful animals needs our care. Though we are not animals care takers but we can take care of them by stop hunting them just to get their tusk. Love the elephant it can give you lots of help.
