Most, but not
all, of the rodents called mice are members of the rodent subclass Myomorpha,
or mouse like rodents. The approximately 1,100 species in this enormous
group are classified in several families. The Old World family Muridae
includes the now ubiquitous house mouse, as well as a great variety
of wild-living Old World species, including the Old World field mouse,
the tiny European harvest mouse ( Micromys minutus ) and the African
tree mice. The cosmopolitan family Cricetidae includes the native New
World mice, such as the deer mouse, American harvest mouse (Reithrodontomys
), the carnivorous grasshopper mouse, the South American field mice,
the pack rat, and the rice rat; it also includes the various Old and
New World species of vole , hamster , lemming , muskrat , and gerbil
. Still other families of the Myomorpha include the dormouse , jumping
mouse , and jerboa . The pocket mouse and the kangaroo rats and mice
are members of the suborder Sciuromorpha, or squirrellike rodents.
House Mouse
The house mouse,
Mus musculus, found throughout the world, is the most familiar of the
mice; many of its races live commensally with humans and are serious
pests, while others live in the wild. It usually measures about 6 in.
(15 cm) long and weighs under 1 oz (28 grams). It has gray to brown
fur, large rounded ears, a pointed muzzle, and a naked scaly tail. Females
produce litters of four to eight young after a gestation period of three
weeks; under favorable conditions they breed throughout the year. The
young mature in two months. House mice, particularly albino strains,
are extensively used in biological and medical experimentation and are
also sometimes kept as pets.
Field Mouse
Field mouse
is a name applied to various wild-living mice in different parts of
the world. The Old World field mice are species of the genus Apodemus,
closely related to the house mouse and found throughout Eurasia and
North Africa. The widely distributed long-tailed field mouse, Apodemus
sylvaticus, is a nocturnal, burrowing creature that prefers succulent
plant food and frequently invades gardens and houses. In North America
the name field mouse (or meadow mouse) is applied to voles. South American
field mice belong to the genus Akodon, with about sixty species distributed
among a wide variety of habitats, including human dwellings. Most of
these resemble long-tailed voles. The name tree mouse is likewise applied
to various arboreal mice and voles in different parts of the world.
