Asian elephant
The Asian elephant ("Elephas maximus"), also called Asiatic elephant, is the only living species of the genus "Elephas" and is distributed in the Indian subcontinent and Southeast Asia, from India and Nepal in the west to Borneo in the south. Three subspecies are recognised—"E. m. maximus" from Sri Lanka, "E. m. indicus" from mainland Asia and "E. m. sumatranus" from the island of Sumatra. The Asian elephant is the largest living land animal in Asia.

The gestation period is 18–22 months, and the female gives birth to one calf, only occasionally twins. The calf is fully developed by the 19th month, but stays in the womb to grow so that it can reach its mother to feed. At birth, the calf weighs about , and is suckled for up to three years. Once a female gives birth, she usually does not breed again until the first calf is weaned, resulting in a four to five year birth interval. Females stay on with the herd, but mature males are chased away.
