How long are kangaroos pregnant 8 months or 85 months?

Kangaroos are pregnant for approximately 33-36 days, which is much shorter than 8 or 85 months.

It's important to note that while the initial pregnancy is short, kangaroos have a unique reproductive system. After giving birth, they can become pregnant again immediately. However, the development of the new embryo is paused for several months until the previous joey is weaned.
