Family Reunion:
Did you know that the hippo's closest relative is the whale? The two mammals share a common ancestor that lived about 60 million years ago.

This ancestor evolved into two groups of animals: early cetaceans, which became whales, dolphins, and porpoises, and a group of unusual land animals.

The only surviving descendent of these land animals is the hippo, making its distant cousin the whale its closest surviving relative!
