Hi there! Did you know that hippos and whales are like cousins in the animal family? Even though hippos live in rivers and lakes and whales live way out in the ocean, they are related!
Long, long ago, their great, great, great-great grandparents were the same animal. Because of that, hippos and whales share some special things.
One of those special things is that they both have their babies in the water! Hippos give birth in rivers or lakes, and whales have their babies in the ocean. This helps keep their babies safe and comfy in the water, where they live.
Isn't it cool that even though hippos walk on land and whales swim in the sea, they are family in a way? Nature is amazing!
