Detailed Explanation
Explanation:
· The Indian elephant is one of three extant recognised subspecies of the Asian elephant and native to mainland Asia.
· The oldest female in an elephant herd is always the leader.
· Elephants have the longest gestation period of all mammals. The average gestation period of an elephant is about 640 to 660 days, or roughly 95 weeks.
· Female elephants live for 60 to 70 years, but only have about four offspring throughout their lifetime.
· Fertility decreases after age 50 in elephants, but the pattern differed from a total loss of fertility in menopausal women with many elephants continuing to reproduce at least until the age of 65 years.
· Therefore it is not till the age of 40 years only.
· Karnataka leads the table with 6,049 elephants followed by Kerala.
