Rodents (from Latin rodere, "to gnaw") are mammals of the order Rodentia, which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws.About 40% of all mammal species are rodents; they are found in vast numbers on all continents except Antarctica.
Mating among rodents can vary from monogamy, to polygyny, to promiscuity.The smallest rodent is the Baluchistan pygmy jerboa, which averages only 4.4 cm (1.7 in) in head and body length, with adult females weighing only 3.75 g (0.132 oz).Rodents have wide-ranging morphologies, but typically have squat bodies and short limbs.They are the most diversified mammalian order and live in a variety of terrestrial habitats, including human-made environments.Species can be arboreal, fossorial (burrowing), or semiaquatic.Many have litters of underdeveloped, altricial young, while others are precocial (relatively well developed) at birth.
The rodent fossil record dates back to the Paleocene on the supercontinent of Laurasia.
In 1986, the Louisiana Fur and Alligator Advisory Council was created in part to develop the market for nutria fur and meat.
To better control the destructive nutria population, trapping for non-commercial purposes may need to be considered.
Rodents greatly diversified in the Eocene, as they spread across continents, sometimes even crossing oceans.
Rodents reached both South America and Madagascar from Africa, and were the only terrestrial placental mammals to reach and colonize Australia.
Rodent groups differ in the arrangement of the jaw muscles and associated skull structures, both from other mammals and amongst themselves.
