Elephants are one of the largest mammals found on earth. There are two species of elephants found in the world today--African elephant and the Asian elephant. They are found in sub-Saharan Africa and South Asia, although Southeast Asia also has the distinction of having elephants.
The trunk of an elephant is probably the most distinctive quality an elephant has. Apart from the basic purpose of respiration, an elephant's trunk serves many other functions like grasping trunks of trees and carrying water in it. Elephants have a pair of tusks that are primarily incisors that have grown out. They serve the purpose of a handy tool for moving objects and is also used as a weapon by elephants. Elephants also use them in defending territory and partners from fellow elephants.
The large ears of an elephant are used in regulating the temperature of the warm-blooded mammal. Asian elephants have smaller ears as compared to their African counterparts. Elephants like to take an occasional dip into the waters of a lake or any water body to keep their temperatures down.
Elephants usually feed on the grass they can find in savannahs and deserts. They are known to live long lives of 70 years. Communication between elephants is through sight, smell and touch. They are known to communicate using infrasound, which are not audible to the human ear. The skin on the forehead of an elephant flutters and vibrates in the process where the air is let to pass through the nasal cavity.
