The Family Muridae is the largest family of mammals, comprising true mice, rats, gerbils, and their relatives, with over 700 species worldwide. These small to medium-sized rodents are highly adaptable, occupying diverse habitats including forests, grasslands, deserts, and urban areas. Murids are typically omnivorous, feeding on seeds, plants, and small invertebrates, and they are known for their high reproductive rates. Many species are nocturnal and social, often living in colonies or burrows. Ecologically, murids play important roles as prey for numerous predators, seed dispersers, and even agricultural pests, while some species, like the house mouse and Norway rat, have significant interactions with humans.
