Discover Nature: Opossums Birth Litters

This week on Discover Nature, we take a look at Missouri’s cousin to the kangaroo.

The Didelphis virginiana, or the Virginia opossum, is the only marsupial found in Missouri. These furbearers grow to 2-3 feet in length (including their 9-15 inch-long tails). They prefer wooded areas near streams for habitat, though they’re common across the state and in urban areas.

Opossums start breeding in February. They complete a 12-13-day gestation period by the end of this month, giving birth to litters of young – each, blind, and less than a half inch long. At birth they make their way to their mother’s fur-lined pouch where they nurse until they are weaned in May.

Despite their often ominous hissing when confronted, opossums pose little danger to humans. In fact, opossums feed on many insects considered injurious by farmers and they also perform an important ecosystem function by feeding on carrion. Opossums fall prey to foxes, bobcats, owls, and other predators.
