    • Elephants are the largest land and grass- eater mammals now living.
    • At birth, it is common for an elephant calf to weigh 120 kilograms.
    • They typically live for 50-70 years. But the oldest elephant lived for 82 years.

    • - The trunk is a union of a nose and upper lip.
    • African elephants are equipped with two fingerlike projections at the tip of their trunk, while Asians have only one.
    • - This organ consists of 100,000 muscle units.
    • The elephant's trunk is sensitive enough to pick up a single blade of grass, yet strong enough to rip the branches off a tree.
    • The trunk is also used for drinking. Elephants suck water up into the trunk—up to 14 liters at a time—and then blow it into their mouths.
    • Elephants also suck up water to spray on their bodies during bathing.
  • 11.
    • The tusks of an elephant are its second upper incisors
    • ( teeth).
    • Tusks grow continuously; an adult male's tusks grow about 18 cm a year.
    • Tusks are used to dig for water, salt and roots and to debark trees .
    • Tusks are also used to move trees and branches when clearing a path.
    • In addition, they are used for marking trees to establish a territory, and occasionally as weapons.
