A mammal (from Latin mamma 'breast') is a vertebrate animal of the class Mammalia (/ m ə ˈ m eɪ l i. ə /). Mammals are characterized by the presence of milk-producing mammary glands for feeding their young, a neocortex region of the brain, fur or hair, and three middle ear bones.

List of mammal genera. There are currently 1,258 genera, 161 families, 27 orders, and around 5,937 recognized living species of mammal. [1] . Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families.
This is a collection of lists of mammal species by the estimated global population, divided by orders. Lists only exist for some orders; for example, the most diverse order - rodents - is missing.
Lists of mammals by region cover mammals found in different parts of the world. They are organized by continent, region, and country, and in some places by sub-national region. Most are full species lists, while those for Australia and the Caribbean have links to more specific species lists.

Molecular studies by molecular systematists, based on DNA analysis, in the early 21st century have revealed new relationships among mammal families. Classification systems based on molecular studies reveal three major groups or lineages of placental mammals, Afrotheria, Xenarthra, and Boreotheria. which diverged from early common ancestors in the C...
A somewhat standardized classification system has been adopted by most current mammalogy classroom textbooks. The following taxonomy of extant and recently extinct mammals is taken from the 6th edition of Vaughan's Mammalogy.This approach emphasizes an initial split between egg-laying prototherians and live-bearing therians. The therians are furthe...
In 1997, the classification of mammals was revised by Malcolm C. McKenna and Susan K. Bell. The Classification of Mammals Above the species level, here referred to as the "McKenna/Bell classification", is a comprehensive work on the systematics, relationships, and occurrences of all mammal taxa, living and extinct, down through the rank of genus. T...
Several important fossil mammal discoveries have been made that have led researchers to question many of the relationships proposed by McKenna and Bell (1997). Additionally, researchers are subjecting taxonomic hypotheses to more rigorous cladistic analyses of early mammal fossils. Luo et al. (2002) summarized existing ideas and proposed new ideas ...
The following classification is a simplified version based on current understanding suitable for non-specialists who want to understand how living genera are related to each other. The classification ignores differences in levels and thus cannot be used to estimate the respective distances between taxa. It also ignores taxa that became extinct in p...
