Hippos are the third largest animal on land. Only elephants and some rhinos are bigger. An adult male hippopotamus can weigh as much as 3200 kg (7000 lbs), but are usually around 2300 kg (5000 lbs). Adult females only weigh about 1800 kg (4000 lbs).
Even though hippos are so big, they only eat plants. In a single night, a hippo may eat as much as 45.5 kg (100 lbs) of grass.
Hippos are the closest living land mammals to whales and dolphins. Perhaps this is why a hippo can hold it's breath for about 5 minutes. They spend much of their day in the water or snoozing on the beach.
