Clitoris is large and may be 15 - 30 cm long but they mate like all other quadrupeds (four legged animals) mounting from the back. The special position of vulva makes the penis when erect to go up like a cobra hood to facilitate penetration into the vagina. Elephants possess two openings on the roof of their mouth called vomeronasal openings, which act as scent glands and plays an important role in courting and mating enabling Flehmen response. Calf at birth is one metre tall and weighs 1 Quintal. Mammary glands are situated between the forelegs and there is no teat as in the case of cows. Elephants have only nipple, with multiple pores like human beings. There is no gall bladder in elephants. Respiration is 10 per minute while standing and 5 per minute during recumbency. Vertical posture like in human beings makes them prone to arthritis. Total number of bones in an elephant is 282 and vertebrae number varies from 56-71. Elephant can stand for long periods. Horses and passerine birds have 'check ligament, which help them to stand while sleeping. Elephants are provided with such feet that can be splayed which help them to stand for long periods.
