Both male and female opossums become sexually mature within their first year of life. On average, Virginia opossums have two litters per year, but this varies depending on their specific location. Females in warmer climates may have three litters per year after a gestation period of 12 to 13 days.

6 lip 2018 · This information sheet reviews natural history, conservation status, and taxonomy, as well as a number of clinically relevant information including (but not limited to) diet, housing, behavior, normal physiologic data and anatomy, restraint, preventive medicine, zoonoses, and important medical conditions seen in the opossum.
The Virginia opossum's ancestors evolved in South America, but spread into North America as part of the Great American Interchange, which occurred mainly after the formation of the Isthmus of Panama about 3 million years ago.
The brief gestation period is 12 to 13 days and up to 25 young may be produced in each litter. Newborns are the size of a honeybee and once delivered they climb up into the mother's pouch. On entering the pouch, each baby must find a nipple and attach itself.
4 dni temu · Opossums are born after an 11-13 day gestation period. The pink, embryonic-looking infants are so small at birth that 20 could fit into a teaspoon. The infants continue to develop inside the pouch.
In northern regions, Virginia opossums average only one litter per year, in warmer climates the number of litters may increase to 3 per year. After an extremely short gestation period of 12 to 13 days, 4 to 25 altricial “honey bee-sized” young are born, although females generally have only 13 mammae, some of which may be nonfunctional.
Life History In Connecticut, opossums usually begin breeding in early March, and the gestation period lasts about 13 days. Opossums produce one to two litters each year. The average litter size is 9, and the young are very tiny (about the size of a navy bean) and blind when first born.
