Female kangaroos have two uteri and three vaginas.

The outside two are for sperm and lead to two uteruses while the middle one is for giving birth.

The urinary tract goes through the middle of the three vaginas, which may be why joeys are so small (40,000 times smaller than adult kangaroos) — there’s no room for a bigger birth canal with the urinary tract in the way.

Because they have two uteruses plus a pouch, to go with the two sperm-vaginas, male kangaroos often have two-pronged penises, that explains why female kangaroos are perpetually pregnant.
