Suborder Myomorpha contains nearly a quarter of all mammal species. These are mainly mouse-like rodents, including gerbils, rats, mice and voles. They are grouped according to the structure of the jaw and the structure of molar teeth: Both their medial and lateral masseter muscles are displaced forward, making them adept at gnawing. The medial masseter muscle goes through the eye socket, a feature unique among mammals.
Most myomorph species belong to superfamily Muroidea. Families under this suborder are:
- Superfamily Muroidea
- Family Platacanthomyidae
- Family Spalacidae
- Family Calomyscidae
- Family Nesomyidae
- Family Cricetidae
- Family Muridae
- Superfamily Dipodoidea
Historically, the definition of the suborder Myomorpha has included one or both of the following.
- Superfamily Geomyoidea
- Family Heteromyidae
- Family Geomyidae
- Superfamily Gliroidea
- Family Gliridae
