The two species of elephant, African and Asian, are the largest land animals in the world. An Asian bull may achieve a height of 10 feet at the shoulder and may weigh up to 6 tons. An African bull can weigh up to 7 tons. African elephants have large ears and two fingers at the end of their trunk.
Asian elephants have much smaller ears and one finger at the end of their trunk.
The elephant's trunk is actually a combination of the upper lip and nose. It is prehensile and can grasp onto many different things such as another elephant's tail. The trunk is sensitive enough to pick up a single blade of grass and strong enough to pick up a heavy log. An elephant can draw up to four gallons of water into its trunk before squirting it into its mouth for a drink. The elephant also uses the trunk to spray its body with water and dirt, protecting the skin from insect bites and exposure to the sun.
