Hippo Attacks Boat In Malawi

Terrifying footage has emerged of a boat narrowly escaping an attack by a 1,500kg hippopotamus.

Sailors on the waterways of Malawi face many dangers, but angry hippos are at the top of the list.

Hippopotamuses can be extremely territorial in the water, as they reproduce, give birth and sleep in lakes and rivers. They are widely considered to be one of the most dangerous animals on the African content and kill 3,000 people every year.

Causes of death include trampling, goring, and drowning caused by incidents such as the one in this video. They have also reportedly been seen biting people's heads off. The most common reason for a hippo attack is getting between a mother and her calf.

Scariest of all, perhaps, is that they sweat a red substance to help them fight sunburn, which makes them look like they're sweating the blood of their prey.
