A safari tour guide in Zambia had a big surprise when travelling on his boat after a huge hippo started to chase it at high speed.

The guide in South Luangwa National Park had to speed up the boat as the hippo launched itself out of the water.

Hippos are big creatures and can be easily angered. They can move very quickly and can be very dangerous.

Fortunately the boat proved too quick and everyone got away safely.
