[29] The average estrous cycle of the Virginia opossum is about 28 days. [30] Opossums do possess a placenta, [31] but it is short-lived, simple in structure, and, unlike that of placental mammals, not fully ...
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.

[43] The female's estrus cycle is 28 days and lasts 36 hours. [43] Gestation lasts 11–13 days and the average litter size is 8–9 infants, although over 20 infants may be born. [43]
Brushtail possums may eat three or four different plant species during a foraging trip, unlike some other arboreal marsupials, such as the koala and the greater glider, which focus on single species. The brushtail possum's rounded molars cannot cut Eucalyptus leaves as finely as more specialised feeders. They are more adapted to crushing their ...

The females have a well-developed pouch, and typically raise only one or two young at a time, less than many other possums. The adults are typically solitary, defending territories marked by scent-gland spray, odiferous saliva, urine, or dung. [3] Most possums conserve the functions of the epipubic bones.
