The Hippopotamus is the third heaviest of all land animals, behind the Elephant and White Rhino. A large males can weight as much at 10,000lbs (4,535kg)! Even at birth they are huge; a newborn weighs around 100lbs (45kg).
Hippopotamuses are one of the most dangerous land mammals in Africa. Males are especially territorial and use their long tusks for fighting over land and harems of females. Threatened Hippos can attack and kill humans, and are able to run at speeds of up to 14mph (30kph).
At night, the Hippos leave the water to graze. Interestingly, they eat very little compared to their body weight, only around 1-1.5%.
Illegal hunting and habitat loss have hurt Hippopotamus numbers, and overall their population is decreasing. They are protected in many areas, but coverage and enforcement is spotty.
