The elephant's gestation period is 22 months, the longest of any land animal. The gestation period for an African elephant averages 640 days; for the Asian elephant it is 645 days. The mother gives birth to a calf that weighs up to 115 kg and stands over 75 cm tall. For more details, please see sites listed below.

Elephantidae is the only surviving family of the order Proboscidea; other, now extinct, members of the order include deinotheres, gomphotheres, mammoths, and mastodons. Male African elephants are the largest extant terrestrial animals and can reach a height of 4 m (13 ft) and weigh 7,000 kg (15,000 lb).

After mating occurs both elephants go their separate ways and 1 calf is born after a 22 month gestation period. The calf weighs approximately 100 Kgs (220 lbs) and stands at 90 cms (35 inches) high. Just a few days after it is born it is able to follow the herd.

Other animals tend to keep their distance; predators such as lions, tigers, hyenas and wild dogs usually target only the young elephants (or calves). Females (cows) tend to live in family groups, which can consist of one female with her calves or several related females with offspring.

The elephant's penis can reach a length of 100 cm (39 in) and a diameter of 16 cm (6 in) at the base. It is S-shaped when fully erect and has a Y-shaped orifice. The female has a well-developed clitoris at up to 40 cm (16 in). The vulva is located between the hind legs instead of near the tail as in most mammals.

The mystery of the elephant's long pregnancy has been unravelled by scientists. A quirk of biology allows the unborn calf to develop in the womb for almost two years, giving it the brain power it needs to survive from birth. The research, detailed in Proceedings of the Royal Society B, will help elephant breeding programmes in zoos.

The brain of an elephant weighs 4.5–5.5 kg (10–12 lb) compared to 1.6 kg (4 lb) for a human brain. While the elephant brain is larger overall, it is proportionally smaller. At birth, an elephant's brain already weighs 30–40% of its adult weight.
