There are two main species of elephant in the world. The African Elephant -- Loxodonta, which is larger with bigger ears and a less docile nature. The ears help the animal to lose heat on the sunny open country it inhabits in Africa. The Indian elephant -- Elephas, is a native of thick forest, so is smaller, with much smaller ears. There have also been reports of pygmy elephants in South East Asia, only 1.5 metres tall, but these are probably extinct. The Indian elephant is 3 metres from the ground to the highest point of the shoulders (males 50 cm bigger). They weigh about four tons, and need 250 kgs of food a day, and 60 gallons of water.They are vegetarians, eating a wide variety of plants. In Thailand, their favourite food is tamarind, but as anyone who has been to an elephant camp knows, they seem to love bananas and sugar cane. Both sexes have tusks, although they are far larger in the male. Some males do not grow tusks, and are supposed to be better workers.
