Mice have a slender body, blunt or tapered muzzle, barely haired, distinguished ears, slim hind feet with bald soles, and sharp, little claws. The thinly hirsute tail seems hairless; it’s going to be regarding as long because the head and body, or it is a lot of shorter. one in every of the most important is that the flat-haired mouse (M. platythrix) of dry land Bharat, consideration regarding eighteen grams (0.6 ounce), with a body ten to twelve cm (4 to four.7 inches) long and a shorter tail (7 to eight cm [2.8 to 3.1 inches]). the littlest is maybe the wood mouse (M. minutoides) of Black Africa, consideration three to twelve grams (0.11 to 0.42 ounce), with a body vi to eight cm (2.3 to 3.1 inches) long and a brief tail of three to six cm (1.2 to 2.3 inches).
There is respectable variation in fur texture and color among the species of Mus. At one extreme square measurethe spiny-furred species within the taxonomic category Pyromys, whose upperparts and undersides square measure lined with flat, channeled spines snuggled in soft undercoat (juveniles don’t seem to be spiny). At the opposite extreme square measure the shrew-mice from island (M. crociduroides) and Java (M. vulcani), whose soft, short, and dense coat seems woolly or velvety. All the opposite species have a soft or slightly coarse, moderately thick coat with short or long hairs. a color combination common to several mice is grey to brown upperparts, white underparts, white feet, and a tail that’s dark on top of and white below. Variations of this pattern embraceupperparts of buff, light-blue grey, achromatic grey, sepia, or chocolate brown, with underparts starting fromwhite to numerous reminder grey, typically coloured with silver or buff. The feet could also be white or constantcolor because the upperparts, and therefore the tail could also be dichromatic or uniformly dark grey to dark brown.
Mice in their natural habitats square measure primarily nocturnal, though some can often forage throughout the day. they’re ground dwellers, though some species are agile climbers and leapers moreover as capable swimmers. a couple of square measure specialised burrowers seldom seen on top of ground. Most species, particularly those living in savannas and grasslands, excavate burrows and chambers during which they build global nests of dry vegetation. In associate intact system, species of Mus, along side alternative small-bodied rodents, square measure preyed upon, typically to associate considerable degree, by reptiles, mammals, and birds (especially owls).
