14. Mantella Frog
Although frogs don’t technically have the same type of pregnancies that mammals do, they do carry around their eggs for a while. Depending on the type of frog, they can carry anywhere from 200 to 20,000 eggs per clutch, per year. That’s a lot of eggs to be carrying around for any animal, and I bet they can’t wait to lay their eggs once it’s the perfect time. This is a golden mantella, which is native to Madagascar and is mostly inactive in the winter months.
