Rodents can be found on all continents except Antarctica. One of the most well known rodents is the rat. Rats have been blamed for many human deaths because they can spread disease. However, they have also helped save many lives by being test subjects for research.
Rodentia is the order of mammals known as rodents, characterised by a single pair of continuously growing incisors in each of the upper and lower jaws which must be kept short by gnawing. Forty percent of mammal species are rodents, and they are found in vast numbers on all continents other than Antarctica. Common rodents include mice, rats, squirrels, porcupines, beavers, guinea pigs, and hamsters. Rodents use their sharp incisors to gnaw wood, break into food, and bite predators. Most rodents eat seeds or plants, though some have more varied diets. Some species have historically been pests, eating seeds stored by people and spreading disease.
