Muridae

(Family)

Overview

[ Back to top ]

Muridae is the largest family of mammals. It contains over 700 species found naturally throughout Eurasia, Africa, and Australia. They have been introduced worldwide. The group includes true mice and rats, gerbils, and relatives.

The family name Muridae is sometimes used in a broader sense to include all members of the superfamily Muroidea. The name comes from the Latin mus (genitive muris), meaning "mouse".

[ Back to top ]

The murids are small mammals, typically around 10 cm (3.9 in) long excluding the tail, but ranging from 4.5 to 8 cm (1.8 to 3.1 in) in the African Pygmy Mouse to 48 cm (19 in) in Cuming's Slender-tailed Cloud Rat. They typically have a slender body with a scaled tail, and pointed snouts with prominent whiskers. However, within these broad traits, there is a wide degree of variation. Many murids have elongated legs and feet allowing them to move with a hopping motion, while others have broad feet and prehensile tails to improve their climbing ability, and yet others have neither adaptation. They are most commonly some shade of brown in color, although many have black, grey, or white markings.[1]

Murids generally have excellent senses of hearing and smell. They live in a wide range of habitats from forest to grassland, and mountain ranges. A number of species, especially the gerbils, are adapted to arid desert conditions, and can survive for a long time with minimal water. They are either herbivores or omnivores, eating a wide range of foods in different species, with the aid of powerful jaw muscles and gnawing incisors that grow throughout life. The dental formula of murids is: Upper: 1.0.0.1-3, lower: 1.0.0.1-3

Murids breed frequently, often producing large litters several times per year. They typically give birth between 20 and 40 days after mating, although this varies greatly between species. The young are typically born blind, hairless, and helpless, although there are exceptions, such as the spiny mice.[1]

Evolution

[ Back to top ]

As with many other small mammals, the evolution of the murids is not well known, as few fossils survive. They probably evolved from hamster-like animals in tropical Asia some time in the early Miocene, and to have only subsequently produced species capable of surviving in cooler climes. They have become especially common worldwide during the Holocene, as a result of hitching a ride with human migrations.[2]

Classification

[ Back to top ]

The Murids are classified in 5 subfamilies, around 150 genera and approximately 710 species.[citation needed]

Rhabdomys

Rhabdomys is a largely Southern African genus of muroid rodents slightly larger than house mice. They are known variously as Striped or Four-Striped mice or rats. Traditionally the genus has been seen as a single species, Rhabdomys pumilio, though modern evidence on the basis of karyotype and mtDNA analysis suggests that it comprises two or more species and subspecies. Dorsally Rhabdomys species display four characteristic black longitudinal stripes on a paler background. [more]

Spalax

The genus Spalax contains the blind, fossorial, or subterranean mole rats, which are one of several types of rodents that are called mole rats. The hystricognath mole rats of the family Bathyergidae are completely unrelated, but some other forms are also in the family Spalacidae. Zokors (subfamily Myospalacinae) and root rats and bamboo rats (subfamily Rhizomyinae) are spalacids sometimes referred to as mole rats. Blind mole rats are in the family Spalacidae, but are unique enough to be given a separate subfamily, Spalacinae. Alternate opinions on taxonomy consider the blind mole rats to be the only members of the family Spalacidae and rank other spalacid subfamilies as full families. Other authors group all members of the superfamily Muroidea into a single family, Muridae. The Spalacinae contains two genera and eight species. Some authorities treat all species as belonging to a single genus, Spalax. [more]
