Rattus is a genusofmuroid rodents, all typically called rats. However, the term rat can also be applied to rodent species outside of this genus.

Species and description[edit]

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[edit]

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.[citation needed]

The genus Rattus proper contains 64 extant species. A subgeneric breakdown of the species has been proposed, but does not include all species.[2]

Species[edit]

Genus Rattus – Typical rats
  • Philippine forest rat (Rattus everetti) – the Philippines
  • Polynesian ratorkiore (Rattus exulans) – originally native to Bangladesh, Myanmar, Thailand, Cambodia, Laos, Vietnam, Malaysia, and Indonesia, but now introduced throughout the Pacific (including most Polynesian, Melanesian, and Micronesian islands, most notably Fiji, Papua New Guinea, New Zealand, Easter Island and Hawaii), as well as the Philippines, Brunei, and Singapore, origin uncertain in Taiwan
  • Hainald's rat (Rattus hainaldi) – Indonesia
  • Hoogerwerf's rat (Rattus hoogerwerfi) – Indonesia
  • Korinch's rat (Rattus korinchi) – Indonesia
  • Maclear's rat (Rattus macleari) – Christmas Island (now extinct)

  • Bulldog rat (Rattus nativitatis) – Christmas Island (now extinct)
  • Kerala rat (Rattus ranjiniae) – India
  • New Ireland forest rat (Rattus sanila) (potentially extinct)
  • Andaman rat (Rattus stoicus) – the Andaman Islands, India
  • Timor rat (Rattus timorensis) – Timor
  • R. norvegicus group
    • Himalayan field rat (Rattus nitidus) – originally native to Bhutan, China, India, Myanmar, Nepal, Thailand, and Vietnam (presence uncertain in Bangladesh), but now introduced to Indonesia, the Philippines, and Palau
    • Brown rat (Rattus norvegicus) – originally native to southeast Siberia, northeast China, and parts of Japan, but now introduced worldwide except Antarctica
    • Turkestan rat (Rattus pyctoris; obs. Rattus turkestanicus) – Afghanistan, China, India, Iran, Kyrgyzstan, Nepal and Pakistan
  • R. rattus group
  • R. xanthurus group
  • R. leucopus group (New Guinean group)
  • R. fuscipes group (Australian group)
  • Phylogeny[edit]

    The following phylogeny of selected Rattus species is from Pagès, et al. (2010).[3]

    Fossil species[edit]

    In contrast to the large number of living species, as of 2024, just four fossil species have been placed in Rattus proper:[4]
