Rodents are mammals belonging to the order Rodentia, characterized by a pair of continuously growing, sharp incisor teeth in both the upper and lower jaws. These teeth must be constantly worn down by gnawing, a behavior essential to their survival. Rodents make up the largest order of mammals, with over 2,000 species adapted to a wide range of environments—from forests and grasslands to urban areas. They play crucial ecological roles as seed dispersers, prey for many predators, and contributors to soil aeration.
- Continuous-growth incisors for gnawing
- Largest order of mammals: ~2,000 species
- Found worldwide except Antarctica
- Important in ecosystems as dispersers, prey, and soil engineers
Rodents are defined by their ever-growing incisors, which require constant gnawing to keep them worn down.
Rodents belong to the order Rodentia.
Mice, squirrels, and beavers are rodents, while rabbits are in Lagomorpha and hedgehogs are insectivores.
Rodents are found on all continents except Antarctica.
What is a Rodent?
All rodents have strong, ever-growing incisors.
Rodents are known for gnawing and high reproductive rates.
No, rabbits belong to Lagomorpha, not Rodentia.
Hamsters, porcupines, and chipmunks are rodents.
Rodents inhabit almost all terrestrial habitats.
Rodents are important in medical research and affect agriculture.
Yes, rodent diets vary from herbivorous to omnivorous.
Rodents are defined by ever-growing incisors and gnawing behavior.
Examples of Rodents: Rodentia
Beavers are rodents; rabbits are lagomorphs.
Mice, gerbils, and porcupines are rodents; shrews and bats are not.
Yes, chipmunks are rodents.
Squirrels and capybaras are rodents.
Yes, guinea pigs are rodents.
Hamsters and gerbils are common rodent pets; ferrets are not.
Rodents disperse seeds, aerate soil, and serve as prey, but are not primary pollinators.
Beavers are indeed rodents.
Yes, the capybara is the largest living rodent.
Rodents are defined by ever-growing incisors and a strong gnawing ability.
