Two prominent murine species have become vital laboratory animals: the brown rat and house mouse are both used as medical subjects. The murines have a distinctive molar pattern that involves three rows of cusps instead of two, the primitive pattern seen most frequently in …

Murines (Murinae) represent an intriguing subfamily within the vast family of rodents, showcasing a blend of diversity, adaptability, and ecological importance. This article will take you on a journey through the world of these remarkable mammals, exploring their characteristics, behaviors, and roles within their ecosystems.

The Old World rats and mice (called Murinae) is a subfamily in the family Muridae. It has about 560 species. This subfamily is larger than all mammal families except the Cricetidae. It is also larger than most mammal orders. The Murinae are native to Africa, Europe, Asia, and Australia.

Muri­nae, the Old World rats and mice, is the largest sub­fam­ily of muroid ro­dents. There are an as­ton­ish­ingly di­verse 561 species in this sub­fam­ily, which are di­vided among 126 gen­era in 29 di­vi­sions. (Musser and Car­leton, 2005)

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.

One relationship to be addressed in murine systematics is the difference between rats and mice. In general, animals that have a body length of less than 5.1–5.9 in (13–15 cm) are called mice, and rats are those that are larger.

Murinae is characterized by a cohesive cluster of external, cranial, postcranial, dental, reproductive, and arterial characteristics (Carleton and Musser, 1984), but derived molar conditions form the primary basis for defining the subfamily.

Self-propelled movement of a cell or organism from one location to another. Component found in mineralized skeletal tissue, (a specialized form of biogenic tissue in which the extracellular matrix is mineralized, and which functions in mechanical and structural support.) Anatomical location of testis; eg: internal, descended, scrotal, inguinal.

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. This subfamily is larger than …
