It’s quite adorable, isn’t it? Looks like a little dinosaurs taken right out of your favorite childhood cartoon! A baby hippopotamuses is often called a “calf.” And did you know that hippopotamuses give birth in water? That’s why this little baby feels very at home there. It may look quite small and lovely now, but it is going to grow to be the third largest, and one of the most dangerous animals on this planet (they are dangerous, only when threatened, of course).
