Rodents Quiz – Small Teeth, Big Impact

Rodents are mammals with a pair of ever-growing incisors in each jaw, which they keep short by gnawing. They make up about 40% of all mammal species, from tiny mice to the capybara of South America.

Rodents live almost everywhere, in deserts, forests, mountains and cities. Beavers engineer wetlands with dams, squirrels plant forests by burying nuts and naked mole-rats live in insect-like colonies with a single queen.

Some rodents cause problems by eating crops or spreading disease, but they also feed many predators and help science. Mice and rats are key to medical research, and guinea pigs and hamsters are popular pets.
