Hippopotamus
World Hippo Day is today! The day reminds us to make sure hippos survive and thrive. The animals’ name is interesting: hippos means horse and potamos means river. So the animals’ name is apt: a river horse. Two types of hippos exist today. The common hippo is on the vulnerable list and the pigmy hippo is on the endangered list. Both types exist in sub-Saharan Africa. They are the third largest land mammal, after elephants and rhinos. Children can learn more at: Hippos.
