Rodents
Rodents are mammals of the order Rodentia, from the Latin rodere “to gnaw”. They are the most numerous group of mammals on the planet, making up about 41% of known species. They are a very diverse group in both size and habitat, ranging from the South American capybara weighing up to 66kg, to the Baluchistan pygmy jerboa, the female adults of which weigh less than 4gm.
Over time rodents have been used as food, for clothing, as pets, some species such as the brown rat, black rat, and the house mouse, are serious pests, eating and spoiling food stored by people, and spreading diseases such as Hantavirus & Salmonellosis.
