A marsupial has a short gestation period, typically shorter than placental. For more information on how these estimates were ascertained, see Wikipedia's articles on gestational age. The gestation figures given here are shown in days. They represent average values and should only be considered as approximations.
Asian elephant gestation periods last anywhere from 18-22 months, while African elephant gestations last a full 22 months. That’s only two months shy of a two-year pregnancy! That’s only two ...
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 ...
A female ovulates once about every 115 days and if fertilized, the gestation period is about 22 months, the longest gestation period of any animal. [ 10 ] Most often, a female gives birth to a single calf (occasionally two might be born), which may weigh between 68–158 kg (150–348 lb). [ 10 ]
The Asian elephant can be found from western India to eastern Borneo in Southeast Asia. A total of three recognized Asian elephant subspecies exist: the indicus, found across mainland Asia, the ...
Two Asian elephant calves playing in a sanctuary in Laos. Female Asian elephants sexually mature around the age of 10~15 and keep growing until 30, while males fully mature at more than the age of 25, and constantly grow throughout their life. [79] [80] Average elephant life expectancy is approximately 60 years. [8]
Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. [2] The time interval of a gestation is called the gestation period. In obstetrics, gestational age refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks. [3]
The female elephants consumed coloured edible glitter to help zookeepers identify their faeces.
