It varies from animal to animal, but here are a few:
elephant - 645 days,
beaver - 122 days,
domestic cat -61 days,
domestic dog - 64 days,
kangaroo - 42 days,
horse - 336 days,
mouse - 19 days,
whale - 490 days,
zebra - 365 days
domestic cow - 285 days
domestic pig - 114 days
human - 260 days
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.
One factor that limits the length of gestation in animals is the size of the pelvis, which determines the maximum size a newborn can be for safe delivery. Another factor is metabolic constraints, as longer gestation periods require more energy and resources for both the mother and the developing fetus. Additionally, environmental factors such as predation risk or seasonal changes may also influence the length of gestation.
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.

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.
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.
What is a gestation period of a pincher
it is different for every animal
The gestation period for each animal is different. For example Elephants have a gestation period of 22 months where as polar bears one of only 8 months.
Only animals which are viviparous (give birth to live offspring) have gestation periods.
This is called the gestation period in mammals, and pregnancy in humans.
Each animal has a different gestation period. A cat is 50 days and a dog is 63 days.

Gestation and pregnancy are synonyms, although gestation is generally used for non-human animals (particularly non-pet animals) and pregnancy is generally reserved for humans (and increasingly companion or pet animals).
No, animals that lay eggs do not have a gestation period. Instead, the embryo develops inside the egg until it is ready to hatch. Gestation typically refers to the time a mammal carries a developing fetus inside its body before giving birth.
Elephants have one of the longest gestation period among mammals. They are pregnant for a period of around 22 months. After the 22 month gestation, they giver birth to a calf that is approximately 250 pounds heavy and stands at around 2.5 feet tall
There are many fish and amphibians for which the female lays soft-shelled unfertilized eggs, which the male then fertilizes. Because the fertilized eggs were never inside the female's body, one might say that there was no gestation period. However, all animals that have internal fertilization have some length of gestation period. For most animals, the gestation period is much shorter than the time between laying the eggs and the eggs hatching: for example, a chicken egg has a gestation period of one day, but the eggs do not hatch until 24 days after being laid. Monotreme mammals (platypuses and echidnas) have longer gestation periods and proportionally shorter distances between the laying of the eggs and the eggs hatching.
