Well-known rodents include mice, rats, squirrels, prairie dogs, chipmunks, chinchillas, porcupines, beavers, guinea pigs, hamsters, gerbils and capybaras. While the largest species, the capybara, can weigh as much as 66 kg, most rodents weigh less than 100 g. The smallest rodent is the Baluchistan pygmy jerboa, which averages only 4.4 cm in head and body length, with adult females weighing only 3.75 g. Rodents have wide-ranging morphologies, but typically have squat bodies and short limbs.
It is the largest living rodent in the world.

Rabbit

Rabbits, hares, and pikas, whose incisors also grow continually, were once included with them, but are now considered to be in a separate order, the Lagomorpha.
Rabbits and hares were formerly classified in the order Rodentia (rodent) until 1912, when they were moved into a new order, Lagomorpha (which also includes pikas).

Fossorial

burrowingdiggingsemifossorial
Species can be arboreal, fossorial (burrowing), or semiaquatic.
Fossorial lifestyles in many rodent species are also considered fossorial as they live in burrows for most of the day, though they may be surface-dwelling during other parts of the day.

Black rat

Rattus rattusblack ratsrats
Some species, in particular, the brown rat, the black rat, and the house mouse, are serious pests, eating and spoiling food stored by humans and spreading diseases.
The black rat (Rattus rattus), also known as ship rat, roof rat, or house rat—is a common long-tailed rodent of the stereotypical rat genus Rattus, in the subfamily Murinae.

House mouse

One of the largest muroids, it is a brown or grey rodent with a head and body length of up to 28 cm long, and a tail slightly shorter than that.

Glires

gliriformsAnagalidaGliriformes
Nonetheless, Rodentia and Lagomorpha are sister groups, sharing a most recent common ancestor and forming the clade of Glires.
Glires (Latin glīrēs, dormice) is a clade (sometimes ranked as a grandorder) consisting of rodents and lagomorphs (rabbits, hares, and pikas).

Myomorpha

myodontMyodontamyomorph
The Myomorpha, such as the brown rat, have enlarged temporalis muscles, making them able to chew powerfully with their molars.
The suborder Myomorpha contains 1,137 species of mouse-like rodents, nearly a quarter of all mammal species.

Kangaroo rat

Rodent species use a wide variety of methods of locomotion including quadrupedal walking, running, burrowing, climbing, bipedal hopping (kangaroo rats and hopping mice), swimming and even gliding.
Kangaroo rats, small rodents of genus Dipodomys, are native to western North America.

Lagomorpha

Rabbits, hares, and pikas, whose incisors also grow continually, were once included with them, but are now considered to be in a separate order, the Lagomorpha.

Hopping mouse

Rodent species use a wide variety of methods of locomotion including quadrupedal walking, running, burrowing, climbing, bipedal hopping (kangaroo rats and hopping mice), swimming and even gliding.
They are rodents, not marsupials, and their ancestors are thought to have arrived from Asia about 5 million years ago.

Tooth

The distinguishing feature of the rodents is their pairs of continuously growing, razor-sharp, open-rooted incisors.
Rodent incisors grow and wear away continually through gnawing, which helps maintain relatively constant length.
