Kids Encyclopedia Facts

Missouri is home to many amazing mammals! From tiny mice to large deer, these creatures play important roles in the state's natural world. Some mammals have always lived here, while others have been brought back after disappearing, or have moved in from other places. This list will help you discover the different types of mammals you might find in Missouri.

Hoofed Mammals (Order: Artiodactyla)

This group includes mammals that have hooves and usually an even number of toes. Most of them are plant-eaters.

Cattle and Bison (Family: Bovidae)

  • American bison (Bison bison): These huge, shaggy animals once roamed Missouri in large herds. They were hunted almost to extinction but have been reintroduced to parts of the state, meaning they were brought back to live in the wild again.

Deer Family (Family: Cervidae)

  • Mule deer (Odocoileus hemionus): These deer are named for their large, mule-like ears. They are usually found in western North America, so seeing one in Missouri is very rare; they are considered a vagrant, meaning they wandered outside their normal range.
