When Do Opossums Have Their Babies?

Opossums, also known as possums, are unique creatures that can be found in various parts of North and South America. These marsupials have a characteristic pouch where they carry their young ones. If you’ve ever come across an opossum, you might wonder when they have their babies. Let’s find out!

Opossums are known for their reproductive habits, which differ from those of many other mammals. They have a relatively short gestation period of only 12 to 13 days. Yes, you read it right! Once the female opossum mates, it takes just around two weeks for her to give birth to her babies.

Interestingly, opossums are polygamous, meaning they mate with multiple partners. This behavior increases the chances of successful fertilization. After mating, the fertilized eggs develop into tiny embryos, which then migrate to the female’s pouch. These embryos attach themselves to the teats inside the pouch, where they will continue to develop and grow.

The opossum’s pouch acts as a protective cradle for the developing embryos. Inside the pouch, the embryos undergo further development, resembling miniature opossums. The newborn opossums, called joeys, are only the size of a honeybee when they are born. They are hairless, blind, and completely dependent on their mother for survival.

Now, let’s move on to some frequently asked questions about opossums and their babies:


1. How many babies do opossums have at once?
