Yes, hippos may look very sweet, but they are dangerous! When they roar, their large teeth become visible! Despite being so heavy, they can run very fast: up to 45 kilometres per hour! Did you know that hippos can walk on the lake floor? However, they don’t swim! Instead, they prefer to live on the edge of the water, where they can also sunbathe.
Hippos are the only mammal species that can talk to each other. Above water, they grunt very loudly at each other. Underwater, the fat in their necks and throat vibrates. The water carries these vibrations to other hippos. In all honesty, it is better to hide under the palm trees and observe them from the shore, where it very safe!
