The shortest known gestation period is the Virginian opossum, which is 12 days. The longest period belongs to the Indian elephant, which has a gestation period of 22 months.
Shortest: American Opossum or Virginian Opossum - 8 days Longest: Asiatic Elephant - 760 days *These are mammals, the longest remains the same but the shortest would be the house fly with a gestation period of 24 hours.
It is believed that the animal with the shortest pregnancy is the bandicoot. They have a gestation period that only last 12 days.
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.

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.
Opossum
Not always, but in general, the larger the animal, the longer the gestation period.
Gestation vetoes from species to species and usually relates to the size of birth-- the smaller the animal the smaller the gestation
The gestation for mice is approximately 19-21 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.
Gestation is used for animal, but pregnancy use for human.
