A member of the family of mice: There are various murids that exist in the world.

Murids generally have very good senses of hearing and smell and they live in a wide range of habitats from forest to grassland, and in mountain ranges.

A number of murids; especially, the gerbils, are adapted to desert conditions and can survive for a long time with a minimal amount of water.

The murids are either herbivores or omnivores; that is, eating plants or a wide variety of foods.
