Myomorphs are found worldwide (apart from Antarctica) in almost all land habitats. They are usually nocturnal seed-eaters. Most myomorph species belong to the superfamily Muroidea: (hamsters, voles, lemmings, true mice, true rats, and gerbils). Historically, the definition of the suborder Myomorpha has included one or both of:

鼠形亚目（学名：Myomorpha），啮齿目中最大的一个亚目，包含了将近25%的哺乳类物种，它们的外表皆与老鼠相似。 鼠形亚目是在啮齿类动物的进化过程中，最成功和最进步的一类。

鼠形亞目（學名： Myomorpha ），嚙齒目中最大的一個亞目，包含了將近25%的哺乳類物種，它們的外表皆與老鼠相似。

The Myomorpha, or mouse-like rodents, are the biggest suborder and include the rat, hamster, and gerbil (Fig. 7.5). They have a total of 16 teeth with no premolars, and rooted molars.

Suborder Myomorpha (mouselike rodents)5 extant families, 5 extinct families containing 44 genera and dating from the Early Eocene to present. The inclusion of Myoxidae is disputed, as evidence has been interpreted to support its placement here or in the Sciuromorpha.

鼠型亚目Myomorpha的种类超过千种，占所有 哺乳动物 种类的1/4，分布几乎遍及世界各地，是世界上最成功的哺乳动物。 鼠型亚目成员体型比较小，咬肌发达，牙齿数量少，除了以对门齿外，仅有几枚臼齿。 鼠型亚目包括种类繁多的鼠总科Murioidea和种类较少的 跳鼠总科 Dipodoidea与睡鼠总科Gliroidea。 鼠型亚目Myomorpha的种类超过千种，占所有哺乳动物种类的1/4，分布几乎遍及世界各地，是世界上最成功的哺乳动物。

2019年3月5日 · Mouse-like rodents (Myomorpha) are a group of rodents that includes rats, mice, voles, hamsters, lemmings, dormice, harvest mice, muskrats, and gerbils. There are about 1,400 species of mouse-like rodents alive today, making them the most diverse (in terms of a number of species) group of all living rodents.

Myomorphs are found all around the world, except Antarctica, in almost all land places. They are usually animals who are more active at night and they are seed-eaters. Most myomorph species belong to superfamily Muroidea:

The suborder Myomorpha contains 1,137 species of mouse-like rodents, nearly a quarter of all mammal species. Included are mice, rats, gerbils, hamsters, lemmings, and voles. They are grouped according to the structure of their jaws and molar teeth.

Myomorpha (鼠形亚目)是啮齿目的一个亚目。 EOL有9个属性数据，包括：
