“Massive” is a good start for describing this round, hulking beast! A full-grown hippo can weigh up to 1-1/2 tons.
Low Risk
The hippopotamus is plentiful in the African wild. Its population numbers are steady, so it has a low risk of becoming extinct.
FUN FACT
The common hippo is amphibious, meaning it lives both on land and in water. Its webbed toes and high-placed eyes, ears, and nostrils allow it to easily take a breath, a look, and a listen while spending long periods of time underwater.
