* New species are constantly being discovered: Scientists are still discovering new mammal species, so any list would quickly become outdated.
* Subspecies and variations: There are numerous subspecies and variations within each mammal species, further expanding the list.
* Synonymy and taxonomic changes: Mammal classification is constantly evolving, with species being reclassified, merged, or split.
However, you can access comprehensive lists and databases of mammals:
* IUCN Red List: The International Union for Conservation of Nature (IUCN) maintains a comprehensive list of all known mammal species, including their conservation status.
* ITIS (Integrated Taxonomic Information System): This system provides a hierarchical classification of all known organisms, including mammals.

Instead of a complete list, you can explore mammals by:
* Order: Carnivora (cats, dogs, bears), Primates (monkeys, apes), Artiodactyla (cattle, deer), Cetacea (whales, dolphins)
* Family: Felidae (cats), Canidae (dogs), Bovidae (cattle, sheep), Hominidae (humans, apes)
* Geographic location: Mammals of North America, Mammals of Africa, Mammals of Asia
* Habitat: Marine mammals, Forest mammals, Desert mammals
By exploring these resources and utilizing these search criteria, you can find the information you need about specific mammals or groups of mammals.
