These Animals Have The Longest Pregnancy Period In The Animal Kingdom

The animals with the longest gestation periods are typically quite large, with elephants, rhinos, and massive ocean creatures often carrying offspring for lengthy periods. However, that's not always the case. There are many factors that play into gestation length, and scientists are still working to uncover some of the miracles of childbirth in the wild. Extended animal pregnancies can often be risky, but these mothers still do what it takes to give their babies the best life imaginable. Below are the animals that are pregnant longer or as long as humans. Via: Ranker
