The Longest and Shortest Mammals gestation
Which mammals have the shortest and longest gestation period?
Almost all mammals give birth to live young, but the gestation periods can not be very similar.
Generally, larger animals have the longest gestation stage, which allows the foetus to be well developed at birth.
Elephants have the longest gestational period, lasting around 95 weeks, By comparison, human pregnancy is typically 40 weeks.
Marsupials have the shortest gestational periods and bear immature young that then must develop in the mother’s bag.
The eastern native cat, The American opossum, and the water opossum ( also a marsupial ) all have a 12-13 day gestation.
