The Mouse, Rat and Guinea-Pig Rodents are a very successful order of placental mammals which colonise almost all habitats. All members of the order are small, the largest member, the Capybara, being about the size of a small pig. Rodents have a number of distinguishing features: they have open rooted sharp teeth, hindgut microbial fermentation chambers, and are coprophagic. Rodents can be divided into three suborders, the Myomorpha, Hystricomorpha and Sciuromorpha. Most laboratory rodents are Myomorphs or Hystricomorphs.
