Rats are typically distinguished from mice by their size. Usually the common name of a large muroid rodent will include the word "rat", while a smaller muroid's name will include "mouse". The common terms rat and mouse are not taxonomically specific. There are 56 known species of rats in the world. [1]
The Natal multimammate mouse (Mastomys natalensis) is a species of rodent in the family Muridae. It is also known as the Natal multimammate rat , the common African rat, or the African soft-furred mouse . [ 1 ]
A pack rat or packrat, also called a woodrat or trade rat, are any species in the North and Central American rodent genus Neotoma. 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 ...
The common terms rat and mouse are not taxonomically specific. Typical mice are classified in the genus Mus, but the term mouse is not confined to members of Mus and can also apply to species from other genera such as the deer mouse . Domestic mice sold as pets often differ substantially in size from the common house mouse. This is attributable ...
It is the second-largest member of the native North American rats, and can weigh up to a pound, roughly the size of an eastern gray squirrel. [5] The fur is long, soft, and brownish-gray or cinnamon in color, while the undersides and feet are white. They have large eyes, and naked ears.
They hold the eggs internally for several weeks, providing nutrients, and then lay them and cover them like birds.

The name combines the Greek oryza "rice" and mys "mouse" and refers to the rat's habit of eating rice. [21] At the time, Oryzomys was recognized either as a full genus or as a subgenus of the now-defunct genus Hesperomys , [ 22 ] but since the 1890s, it has been universally recognized as a genus distinct from Hesperomys , with the marsh rice ...
The new genome rat assembly, mRatBN7.2, was generated by the Darwin Tree of Life Project at the Wellcome Sanger Institute and has been accepted into the Genome Reference Consortium. mRatBN7.2 was derived from a male BN/NHsdMcwi rat that is a direct descendant of the female BN rat previously sequenced.
