Rodents make up the largest order of mammals, with over 40% of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing. Most rodents are small, although the capybara can weigh up to . According to the IUCN listing, Mexico has more rodent species (236 as of April 2011) than any other country in the world (Brazil is second with 222). Of Mexico's rodents, 2% are caviomorphs, 14.5% are sciurids, 25.5% are castorimorphs and 58% are cricetids. This distribution is fairly similar to that of the remainder of North America (although sciurids are relatively twice as abundant to the north, at the expense of cricetids), but is very different from that of South America, where the corresponding figures are 36%, 3%, 1% and 60%. Of Mexico's cricetids, 17% are sigmodontine, while the figure for South America is 99.5%.

Order: Carnivora (carnivorans)

----

There are over 260 species of carnivorans, the majority of which feed primarily on meat. They have a characteristic skull shape and dentition. Mexico has more native Mephitidae, mephitids than any other country, with two thirds of extant species being present. Only Costa Rica and Panama have more Procyonidae, procyonid species (one more) than Mexico (it is tied with Colombia in this respect). Large extinct carnivorans that lived in the area prior to the coming of humans include the saber-toothed cat ''Smilodon fatalis'', the scimitar cat ''Homotherium, Homotherium serum'', American lions, American cheetahs, dire wolves and Arctodus, short-faced bears. *Suborder: Feliformia **Family: Felidae (cats) ***Subfamily: Felinae ****Genus: ''Herpailurus'' ***** Jaguarundi, ''H. yagouaroundi'' ****Genus: ''Leopardus'' ***** Ocelot, ''L. pardalis'' ***** Margay, ''L. wiedii'' ****Genus: ''Lynx'' ***** Bobcat, ''L. rufus'' ****Genus: ''Puma (genus), Puma'' ***** Cougar, ''P. concolor'' ***Subfamily: Pantherinae ****Genus: ''Panthera'' ***** Jaguar, ''P. onca'' *Suborder: Caniformia **Family: Canidae (dogs, foxes) ***Genus: ''Canis'' **** Coyote, ''C. latrans'' **** Gray wolf, ''C. lupus'' reintroduced ***** Mexican wolf, ''C. l. baileyi'' reintroduced ***Genus: ''Urocyon'' **** Gray fox, ''U. cinereoargenteus'' ***Genus: ''Vulpes'' **** Kit fox, ''V. macrotis'' **Family: Ursidae (bears) ***Genus: ''Ursus (biology), Ursus'' **** American black bear, ''U. americanus'' **** Brown bear, ''U. arctos'' extirpated ***** California grizzly bear, ''U. a. californicus'' ***** Mexican grizzly bear, ''U. a. horribilis'' **Family: Mephitidae ***Genus: ''Conepatus'' **** American hog-nosed skunk, ''C. leuconotus'' **** Striped hog-nosed skunk, ''C. semistriatus'' ***Genus: ''Mephitis (genus), Mephitis'' **** Hooded skunk, ''M. macroura'' **** Striped skunk, ''M. mephitis'' ***Genus: ''Spilogale'' **** Southern spotted skunk, ''S. angustifrons'' **** Western spotted skunk, ''S. gracilis'' **** Eastern spotted skunk, ''S. putorius'' **** Pygmy spotted skunk, ''S. pygmaea'' **Family: Mustelidae (mustelids) ***Genus: ''Tayra, Eira'' **** Tayra, ''E. barbara'' ***Genus: ''Sea otter, Enhydra'' **** Sea otter, ''E. lutris'' ***Genus: ''Galictis'' **** Greater grison, ''G. vittata'' ***Genus: ''Lontra'' **** North American river otter, ''L. canadensis'' presence uncertain **** Neotropical river otter, ''L. longicaudis'' ***Genus: ''Mustela'' **** Black-footed ferret, ''M. nigripes'' extirpated ***Genus: ''Neogale'' **** Long-tailed weasel, ''N. frenata'' ***Genus: ''Taxidea'' **** American badger, ''T. taxus'' **Family: Procyonidae (raccoons) ***Genus: ''Bassariscus'' **** Ring-tailed cat, Ringtail, ''B. astutus'' **** Cacomistle, ''B. sumichrasti'' ***Genus: ''Nasua'' **** White-nosed coati, ''N. narica'' ***** Cozumel Island coati, ''N. n. nelsoni'' ***Genus: ''Potos'' **** Kinkajou, ''P. flavus'' ***Genus: ''Procyon (genus), Procyon'' **** Common raccoon, ''P. lotor'' ***** Tres Marias raccoon, ''P. l. insularis'' **** Cozumel raccoon, ''P. pygmaeus'' **Clade Pinnipedia (seals, sea lions and walruses) ***Family: Otariidae (eared seals, sea lions) ****Genus: ''Arctocephalus'' ***** Galápagos fur seal, ''A. galapagoensis'' vagrant ***** Guadalupe fur seal, ''A. townsendi'' ****Genus: ''Callorhinus'' ***** Northern fur seal, ''C. ursinus'' ****Genus: ''Zalophus'' ***** California sea lion, ''Z. californianus'' ***Family: Phocidae (earless seals) ****Genus: ''Mirounga'' ***** Northern elephant seal, ''M. angustirostris'' ****Genus: ''Neomonachus'' ***** Caribbean monk seal, ''N. tropicalis'' ****Genus: ''Phoca'' ***** Harbor seal, ''P. vitulina''

Order: Perissodactyla (odd-toed ungulates)

----

The odd-toed ungulates are browsing and grazing mammals. They are usually large to very large, and have relatively simple stomachs and a large middle toe. Tapirids were more widespread before humans appeared, formerly being present in temperate North America as well as the tropical regions they are found in today. Native Equidae, equids once lived in the region, having evolved in North America over Evolution of the horse, a period of 50 million years, but died out around the time of the first arrival of humans, along with at least one ungulate of South American origin, the notoungulate ''Mixotoxodon''. Sequencing of collagen from a fossil of one recently extinct notoungulate has indicated that this order was closer to the perissodactyls than any extant mammal order. *Family: Tapiridae (tapirs) **Genus: ''Tapirus'' *** Baird's tapir, ''T. bairdii''

Order: Artiodactyla (even-toed ungulates and cetaceans)

----

The even-toed ungulates are ungulates whose weight is borne about equally by the third and fourth toes, rather than mostly or entirely by the third as in perissodactyls. There are about 220 noncetacean artiodactyl species, including many that are of great economic importance to humans. All of Mexico's extant ungulates are of Nearctic realm, Nearctic origin. Prior to the arrival of humans, camelids, which evolved in North America, also lived in the region, as did additional antilocaprids (e.g., ''Capromeryx minor''). *Family: Tayassuidae (peccaries) **Genus: ''Dicotyles'' *** Collared peccary, ''D. tajacu'' **Genus: ''Tayassu'' *** White-lipped peccary, ''T. pecari'' *Family: Cervidae (deer) **Subfamily: Cervinae ***Genus: ''Cervus'' **** Elk, ''C. canadensis'' extirpated ***** Merriam's elk, ''C. c. merriami'' **Subfamily: Capreolinae ***Genus: ''Brocket deer, Mazama'' **** Central American red brocket, ''M. temama'' ***Genus: ''Odocoileus'' **** Mule deer, ''O. hemionus'' **** Yucatan brown brocket, ''O. pandora'' **** White-tailed deer, ''O. virginianus'' *Family: Antilocapridae (pronghorn) **Genus: ''Antilocapra'' *** Pronghorn, ''A. americana'' reintroduced **** Mexican pronghorn, ''A. a. mexicana'' **** Baja California pronghorn, ''A. a. peninsularis'' **** Sonoran pronghorn, ''A. a. sonoriensis'' *Family: Bovidae (cattle, antelope, sheep, goats) **Subfamily: Bovinae ***Genus: ''Bison'' **** American bison, ''B. bison'' reintroduced *****Plains bison, ''B. b. bison'' reintroduced **Subfamily: Caprinae ***Genus: ''Ovis'' **** Bighorn sheep, ''O. canadensis'' ***** Desert bighorn sheep, ''O. c. nelsoni''

Order: Cetacea (whales, dolphins and porpoises)

----

Atlantic spotted dolphin (Stenella frontalis) NOAA

Pacific white-sided dolphins (Lagenorhynchus obliquidens) NOAA

The order Cetacea includes whales, dolphins and porpoises. They are the mammals most fully aquatic adaptation, adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion underwater. Their closest extant relatives are the Hippopotamidae, hippos, which are artiodactyls, from which cetaceans descended; cetaceans are thus also artiodactyls. Lagoons on the coast of Baja California Sur provide calving grounds for the eastern Pacific population of gray whales. The vaquita of the northern Gulf of California is the world's smallest and The world's 100 most threatened species, most endangered cetacean. *Parvorder: Mysticeti **Family: Balaenopteridae ***Subfamily: Balaenopterinae ****Genus: ''Balaenoptera'' ***** Northern minke whale, ''Balaenoptera acutorostrata'' LC ***** Sei whale, ''Balaenoptera borealis '' EN ***** Bryde's whale, ''Balaenoptera edeni'' DD critically endangered population in Gulf of Mexico ***** Blue whale, ''Balaenoptera musculus'' EN ***** Fin whale, ''Balaenoptera physalus'' ****** Northern fin whale, ''B. p. physalus'' VU ***Subfamily: Megapterinae ****Genus: ''Megaptera'' ***** Humpback whale, ''Megaptera novaeangliae'' LC **Family: Eschrichtiidae ***Genus: ''Eschrichtius'' **** Gray whale, ''Eschrichtius robustus'' LC **Family: Balaenidae ***Genus: ''Eubalaena'' ****North Pacific right whale, ''Eubalaena japonica'' CR extremely rare **** North Atlantic right whale, ''Eubalaena glacialis'' CR possibly seen historically *Parvorder: Odontoceti **Family: Physeteridae (sperm whales) ***Genus: ''Physeter'' **** Sperm whale, ''Physeter macrocephalus'' VU **Family: Kogiidae ***Genus: ''Kogia'' **** Pygmy sperm whale, ''Kogia breviceps'' DD **** Dwarf sperm whale, ''Kogia sima'' DD **Family: Ziphidae ***Genus: ''Ziphius'' **** Cuvier's beaked whale, ''Ziphius cavirostris'' LC ***Genus: ''Berardius'' **** Baird's beaked whale, ''Berardius bairdii'' DD ***Subfamily: Hyperoodontinae ****Genus: ''Indopacetus'' ***** Tropical bottlenose whale, ''Indopacetus pacificus'' DD ****Genus: ''Mesoplodon'' ***** Blainville's beaked whale, ''Mesoplodon densirostris'' DD ***** Gervais' beaked whale, ''Mesoplodon europaeus'' DD ***** Ginkgo-toothed beaked whale, ''Mesoplodon ginkgodens'' DD ***** Pygmy beaked whale, ''Mesoplodon peruvianus'' DD **Superfamily: Delphinoidea ***Family: Phocoenidae (porpoises) ****Genus: ''Phocoena'' ***** Vaquita, ''P. sinus'' ****Genus: ''Phocoenoides'' ***** Dall's porpoise, ''Phocoenoides dalli'' LC ***Family: Delphinidae (marine dolphins) ****Genus: ''Rough-toothed dolphin, Steno'' ***** Rough-toothed dolphin, ''Steno bredanensis'' LC ****Genus: ''Tursiops'' ***** Bottlenose dolphin, ''Tursiops truncatus'' LC ****Genus: ''Stenella'' ***** Pantropical spotted dolphin, ''Stenella attenuata'' LC ***** Clymene dolphin, ''Stenella clymene'' DD ***** Striped dolphin, ''Stenella coeruleoalba'' LC ***** Atlantic spotted dolphin, ''Stenella frontalis'' DD ***** Spinner dolphin, ''Stenella longirostris'' DD ****Genus: ''Common dolphin, Delphinus'' ***** Long-beaked common dolphin, ''Delphinus capensis'' DD ***** Short-beaked common dolphin, ''Delphinus delphis'' LC ****Genus: ''Lagenodelphis'' ***** Fraser's dolphin, ''Lagenodelphis hosei'' LC ****Genus: ''Lissodelphis'' ***** Northern right whale dolphin, ''Lissodelphis borealis'' LC ****Genus: ''Sagmatias'' ***** Pacific white-sided dolphin, ''Sagmatias obliquidens'' LC ****Genus: ''Risso's dolphin, Grampus'' ***** Risso's dolphin, ''Grampus griseus'' LC ****Genus: ''Peponocephala'' ***** Melon-headed whale, ''Peponocephala electra'' LC ****Genus: ''Feresa'' ***** Pygmy killer whale, ''Feresa attenuata'' DD ****Genus: ''Pseudorca'' ***** False killer whale, ''Pseudorca crassidens'' DD ****Genus: ''Orcinus'' ***** Orca, ''Orcinus orca'' DD ****Genus: ''Globicephala'' ***** Short-finned pilot whale, ''Globicephala macrorhynchus'' DD
