3. Introduction
The mammals of Rodentia are called rodents’
They are found in vast numbers on all continents other
than Antarctica.
Common rodents
are mice, rats,squirrels, porcupines, and guinea pigs, etc.

4. feeding
Rodents use their sharp incisors to cut wood, and bite
predators.
Most rodents eat seeds or plants, cutting wood, Nearly all
rodents feed on plants, seeds in particular, but a number of
species eat insects .

5. Range of orders
Rodents make up the largest order of mammals. With about
2,277 species of rodents,
over 40% of mammalian species belong to the order.
Their success is probably due to their small size, short
breeding cycle, and ability to cut and eat a wide variety of
foods.
Rodents are found in vast numbers on all continents except
Antarctica, most islands, and in all habitats except oceans.
They are the only placental order.

6. Dentition

specimens weighing up to 91 kg.
