Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. D'Orbigny's tuco-tuco (Ctenomys dorbignyi) is a species of rodent in the family Ctenomyidae, named after French naturalist Alcide d'Orbigny. It is found in northeast Argentina. Rodentia is an order of mammals also known as rodents, characterised by two continuously growing incisors in 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, chipmunks, guinea pigs, and voles. Rodents have sharp incisors that they use to gnaw wood, break into food, and bite predators. Most eat seeds or plants, though some have more varied diets. Some species have historically been pests, eating seeds stored by people and spreading disease.
