Another factor is due to the shortage of food stocks during winter as the insects are being driven away and as the result, bat hibernate in pregnant condition. [ 24 ] In pinnipeds , the purpose of delayed implantation is in order to increase survival chance of the young animals as the mother ensure that the neonates are born at an optimal season.
Rothschild's giraffes mate at any time of the year and have a gestation period of 14 to 16 months, typically giving birth to a single calf. They live in small herds, with males and females (and their calves) living separately, only mixing for mating. [12]
For example, a cat's gestation normally takes 58–65 days while an elephant's takes nearly 2 years (21 months). [3] However, growth does not necessarily determine the length of gestation for all species, especially for those with a breeding season. Species that use a breeding season usually give birth during a specific time of year when food ...
Another female giraffe at the zoo, Iggy, is also pregnant and expected to give birth soon. Gestation periods in Masai giraffes can last up to 15 months and calves can be six feet tall when they ...
It is characterised by its long, slender neck and limbs. The antelope is 80–105 centimetres (2 feet 7 inches – 3 feet 5 inches) tall, and weighs between 18 and 52 kilograms (40 and 115 pounds). Two types of colouration are clearly visible on the smooth coat: the reddish brown back or the "saddle", and the lighter flanks, fawn to buff.
Reticulated giraffes are a subspecies of giraffes. In fact, Kipekee is the first giraffe of her kind without spots since one that was born in Tokyo in 1972, according to David Bright.

Embryonic diapause [a] (delayed implantation in mammals) is a reproductive strategy used by a number of animal species across different biological classes.In more than 130 types of mammals where this takes place, the process occurs at the blastocyst stage of embryonic development, [1] and is characterized by a dramatic reduction or complete cessation of mitotic activity, arresting most often ...
