Species and description
The best-known Rattus species are the black rat (R. rattus) and the brown rat (R. norvegicus). The group is generally known as the Old World rats or true rats and originated in Asia. Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over 500 grams (1.1 lb) in the wild.
Taxonomy of Rattus
The genus Rattus is a member of the giant subfamily Murinae. Several other murine genera are sometimes considered part of Rattus: Lenothrix, Anonymomys, Sundamys, Kadarsanomys, Diplothrix, Margaretamys, Lenomys, Komodomys, Palawanomys, Bunomys, Nesoromys, Stenomys, Taeromys, Paruromys, Abditomys, Tryphomys, Limnomys, Tarsomys, Bullimus, Apomys, Millardia, Srilankamys, Niviventer, Maxomys, Leopoldamys, Berylmys, Mastomys, Myomys, Praomys, Hylomyscus, Heimyscus, Stochomys, Dephomys and Aethomys.
The genus Rattus proper contains 64 extant species. A subgeneric breakdown of the species has been proposed, but does not include all species.[1]
