Possums give birth after only twelve days of gestation, further allowing their babies to develop in their pouch for another two months. Baby possums later travel on their mother’s back for ...
Pygmy possums can give birth to up to six young in every litter. Pygmy possums are often mistaken for mice due to their size, shape, and fawn coloring, but if you look closer, there are several ...
Opossums do possess a placenta, [31] but it is short-lived, simple in structure, and, unlike that of placental mammals, not fully functional. [32] The young are therefore born at a very early stage, although the gestation period is similar to that of many other small marsupials, at only 12 to 14 days. [33] They give birth to litters of up to 20 ...
There is a positive relationship between mass at birth and length of gestation in eutherian mammals. [17] Larger mammals are more likely to produce a well-developed neonate than small mammals. Large mammals develop at an absolute slower rate compared to small mammals.
The common opossum (Didelphis marsupialis), also called the southern or black-eared opossum [2] or gambá, and sometimes called a possum, is a marsupial species living from the northeast of Mexico to Bolivia (reaching the coast of the South Pacific Ocean to the central coast of Peru), including Trinidad and Tobago and the Windwards in the Caribbean, [2] where it is called manicou.

Eastern pygmy possums typically breed twice a year, although they may breed a third time if food is plentiful. Females have a well-developed pouch with four to six teats, and usually give birth to four young, although larger litters are not uncommon. Gestation lasts around 30 days, after which the young spend 33 to 37 days sheltering in the pouch.
Western pygmy possums can breed throughout the year, although they do so more commonly in the spring, and give birth to litters of four to six young. The mother often carries more than six embryos at a time in her womb, but because she has only six teats, and marsupial young remain attached to an individual teat for much of their early lives ...
