Lions, cheetas, and coyotes are able to protect themselves by running very fast. Other large animals travel in groups. Elephants, zebras and rhinoceros roam the grasslands in huge herds. These herds are able to protect the smaller, weaker animals from lions and other predators. Here in the United States, buffalo used to roam the grasslands, but no so much anymore.
Buffalo are huge animals with thick, brown fur.
A long time ago, many people hunted the buffalo. Today, a person can not shoot a buffalo, so the mammal is slowly making a comeback. In other grassland areas, such as Africa, there is a big problem with people shooting animals. Elephants and rhinoceros are shot for their tusks, and lions are killed for their fur.
