Caribou are a species of deer that wolves eat in both Alpha and Omega and real life. They are also called reindeer (mainly in Europe). These animals live in groups called herds. Caribou are herbivores.
Caribou have thick, wiry pelts; very well developed for the cold times on the tundra. They have strong hooves and thin, willowy legs. Both male and female caribou have antlers.
- The largest caribou herd in the world had over 100,000 members.
