What Animal Has Longest Pregnancy?

For the human species,┬áspecifically females, the gestation period of nine months can often seem like forever. In the animal kingdom, the rule of thumb is the larger the animal, the longer gestation period. So in the context of the gestation period of all mammals, humans really don’t haven’t it that bad. For all the burden of a long gestation period, however, mammals are bestowed with longer lives — evidence for the second rule of thumb: the larger the animal, the longer the life span.
