Animal gestation periods - What are the shortest and the longest and their lengths?

Two marsupials share the shortest gestation period. The Virginian opossum and the yapok (an unusual, rare water opossum) have a gestation period period of 12-13 days. Several sources cite the Eastern quoll of Australia as also having a gestation period of 12-13 days, but this is incorrect. The Eastern quoll's gestation period is 21 days. The longest known gestation period of any animal is that of the African elephant. Its gestation period averages 660 days but can extend to 760 days.


What is the gestation period for a pig and how does it compare to human gestation?

The gestation period for a pig is around 3 months, 3 weeks, and 3 days (approximately 114 days). In comparison, the gestation period for a human is around 9 months (approximately 280 days), making human gestation significantly longer than that of a pig.


Name the mammal that has the shortest gestation period of 8 days?

It is a fallacy that any mammal has a gestation period of 8 days. Two marsupials share the shortest gestation period. The Virginian opossum and the yapok (an unusual, rare water opossum) have a gestation period period of 12-13 days. Several sources cite the Eastern quoll of Australia as also having a gestation period of anywhere between 8 and 13 days, but this is incorrect. The Eastern quoll's gestation period is 20-24 days.


Which animal has the shortest gestation period?

Marsupials in general have short gestation periods since the babies are born into the pouch at a rather underdeveloped state. I think the shortest animal gestation period if I remember correctly is that of the opposum, it's 12-13 days long.


How does gestation vary among animals?

Gestation varies widely among animals, with some species like elephants having a gestation period of around 22 months, while others like mice have a gestation period of only 19-21 days. The length of gestation is influenced by factors such as the species' size, metabolic rate, and reproductive strategies.
