Small mammal
From Wikipedia, the free encyclopedia
Small mammals or micromammals are a subdivision of mammals based on their body mass and size. Different values have been used as the upper limit. The International Biological Programme has defined small mammals as species weighing up to 5 kg.[1][2][3] Alternatively, the International Union for Conservation of Nature (IUCN) groups the orders of rodents, tree shrews and eulipotyphlans (insectivores) together under the term small mammals.[4]
A significant majority of mammal species falls into the category of small mammals.[1][2] They are found in a great range of habitats and climate zones.[3]
