List of mammalian gestation durations. This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically ...
The Asian elephant (Elephas maximus), also known as the Asiatic elephant, is a species of elephant distributed throughout the Indian subcontinent and Southeast Asia, from India in the west to Borneo in the east, and Nepal in the north to Sumatra in the south. Three subspecies are recognised— E. m. maximus, E. m. indicus and E. m. sumatranus.
The duration of this period varies between species. For most species, the amount a fetus grows before birth determines the length of the gestation period. Smaller species normally have a shorter gestation period than larger animals. [2] For example, a cat's gestation normally takes 58–65 days while an elephant's takes nearly 2 years (21 ...
Jade, seventeen, is currently pregnant with her first calf via artificial insemination. The father, Jake, lives at the Denver Zoo. She’s due to give birth later this year or early in 2025, and ...
Marsupials have a very short gestation period—usually between 12.5 and 33 days, [41] but as low as 10.7 days in the case of the stripe-faced dunnart and as long as 38 days for the long-nosed potoroo. [42]
The Indian elephant (Elephas maximus indicus) is one of three extant recognized subspecies of the Asian elephant, native to mainland Asia. The species is smaller than the African elephant species with a convex back and the highest body point on its head. The species exhibits significant sexual dimorphism with a male reaching an average shoulder ...
Gestation. Drawing of a fetus in utero. Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). [1] It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for ...
Humans are used to a 40-week gestation period (give or take) but when it comes to elephants, moms-to-be need to be a lot more patient. African elephants are the largest land animal on Earth, and ...
