Although none of them are native to the Americas, a few species, notably the house mouse and black rat, have been introduced worldwide. Murids occupy a broad range of ecosystems from tropical forests to tundras. Fossorial, arboreal, and semiaquatic murid species occur, though most are terrestrial animals. [3]
The similar species Rattus norvegicus, the brown rat or wharf rat, has also been carried worldwide by ships in recent centuries. [ 61 ] The ship or wharf rat has contributed to the extinction of many species of wildlife, including birds, small mammals, reptiles, invertebrates, and plants, especially on islands.
A mouse (pl.: mice) is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse (Mus musculus). Mice are also popular as pets. In some places, certain kinds of field mice are locally common. They are ...
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. Accidentally introduced species of rodents are often considered to be invasive and have caused the extinction of numerous species, such as island birds, the dodo being an example ...
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species.Members of this subfamily are called murines.In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents.

Pack rats have a rat-like appearance, with long tails, large ears, and large, black eyes. Pack rats are noticeably larger than deer mice, harvest mice, and grasshopper mice, and are usually somewhat larger than ...
For certain studies, they are also favored over the laboratory mouse (M. musculus) and the laboratory rat (Rattus norvegicus). Apart from their importance in studying infectious diseases, Peromyscus species are useful for studying phylogeography, speciation, chromosomes, genetics, ecology, population genetics, conservation [10] and evolution in ...
The genus Mus or typical mice refers to a specific genus of muroid rodents, all typically called mice (the adjective "muroid" comes from the word "Muroidea", which is a large superfamily of rodents, including mice, rats, voles, hamsters, gerbils, and many other relatives), though the term can be used for other rodents.
