Dasyuromorphia is an order comprising most of the Australian carnivorous marsupials, including quolls, dunnarts, the numbat, the Tasmanian devil, and the extinct thylacine. In Australia, the exceptions include the omnivorous bandicoots and the marsupial moles. Numerous South American species of marsupials are also carnivorous, as were some extinct members of the order Diprotodontia, including extinct kangaroos and thylacoleonids, and some members of the partially extinct clade Metatheria and all members of the extinct superorder Sparassodonta.
The Cuban solenodon or almiquí is a small, furry, shrew-like mammal endemic to mountainous forests on Cuba. It is the only species in the genus Atopogale. An elusive animal, it lives in burrows and is only active at night when it uses its unusual toxic saliva to feed on insects. The solenodons, native to the Caribbean, are one of only a few mammals that are venomous.
Solenodons are venomous, nocturnal, burrowing, insectivorous mammals belonging to the family Solenodontidae. The two living solenodon species are the Cuban solenodon and the Hispaniolan solenodon. Threats to both species include habitat destruction and predation by non-native cats, dogs, and mongooses, introduced by humans to the solenodons' home islands to control snakes and rodents.
Heptaxodontidae, rarely called giant hutia, is an extinct family of large rodents known from fossil and subfossil material found in the West Indies. One species, Amblyrhiza inundata, is estimated to have weighed between 50 and 200 kg, reaching the weight of an eastern gorilla. This is twice as large as the capybara, the largest rodent living today, but still much smaller than Josephoartigasia monesi, the largest rodent known. These animals were probably used as a food source by the pre-Columbian peoples of the Caribbean.
Simplicidentata is a group of mammals that includes the rodents and their closest extinct relatives. The term has historically been used as an alternative to Rodentia, contrasting the rodents with their close relatives the lagomorphs. However, Simplicidentata is now defined as including all members of Glires that share a more recent common ancestor with living rodents than with living lagomorphs. Thus, Simplicidentata is a total group that is more inclusive than Rodentia, a crown group that includes all living rodents, their last common ancestor, and all its descendants. Under this definition, the loss of the second pair of upper incisors is a synapomorphic feature of Simplicidentata. The loss of the second upper premolar (P2) has also been considered as synapomorphic for Simplicidentata, but the primitive simplicidentate Sinomylus does have a P2.
Hutias are moderately large cavy-like rodents of the subfamily Capromyinae that inhabit the Caribbean islands. Most species are restricted to Cuba, but species are known from all of the Greater Antilles, as well as The Bahamas and (formerly) Little Swan Island off of Honduras.
The dwarf hutia is a small, critically endangered, rat-like mammal known only from Cuba. Aside from tracks, it was last seen in 1937 and may be extinct. It gives birth to only a single offspring at a time, and is threatened by habitat loss and non-native species such as rats and mongoose. The dwarf hutia belongs to the hutia subfamily (Capromyinae), a group of rodents native to the Caribbean that are mostly endangered or extinct.
Nesophontes, sometimes called West Indies shrews, is the sole genus of the extinct, monotypic mammal family Nesophontidae in the order Eulipotyphla. These animals were small insectivores, about 5 to 15 cm long, with a long slender snout and head and a long tail. They were endemic to the Greater Antilles, in Cuba, Hispaniola, Puerto Rico, the United States Virgin Islands, and the Cayman Islands.
Geocapromys is a genus of rodent belonging to the hutia subfamily and are currently only found on the Bahamas and Jamaica. However, they formerly ranged throughout the Caribbean, from Cuba to the Cayman Islands to even islands off mainland Central America.
The island of Great Britain, along with the rest of the archipelago known as the British Isles, has a largely temperate climate. It contains a relatively small fraction of the world's wildlife. The biota was severely diminished in the last ice age, and shortly thereafter was separated from the continent by the English Channel's formation. Since then, humans have hunted the most dangerous forms to extinction, though domesticated forms such as the dog and the pig remain. The wild boar has subsequently been reintroduced as a meat animal.
The black-tailed hutia, also known as the bushy-tailed hutia, is a small, furry, rat-like mammal found only in Cuba. It lives in lowland moist forests and is threatened by habitat loss. It is a member of the hutia subfamily (Capromyinae), a group of rodents native to the Caribbean that are mostly endangered or extinct.
Marcano's solenodon is an extinct species of mammal in the family Solenodontidae known only from skeletal remains found on the island of Hispaniola.
Lasiorhinus is the genus containing the two extant hairy-nosed wombats, which are found in Australia. The southern hairy-nosed wombat is found in some of the semiarid to arid regions belt from New South Wales southwest to the South Australia-Western Australia border. The IUCN categorises it as Near Threatened. Conversely, the northern hairy-nosed wombat is categorised as Critically Endangered and only survives in a 3-square-kilometre (1.2 sq mi) range within the Epping Forest National Park in Queensland, but formerly also existed in Victoria and New South Wales.
A unique and diverse albeit phylogenetically restricted mammal fauna is known from the Caribbean region. The region—specifically, all islands in the Caribbean Sea and the Bahamas, Turks and Caicos Islands, and Barbados, which are not in the Caribbean Sea but biogeographically belong to the same Caribbean bioregion—has been home to several families found nowhere else, but much of this diversity is now extinct.
Hyraxes, also called dassies, are small, thickset, herbivorous mammals in the order Hyracoidea. Hyraxes are well-furred, rotund animals with short tails. Typically, they measure between 30 and 70 cm long and weigh between 2 and 5 kg. They are superficially similar to pikas and marmots, but are more closely related to elephants and sea cows.
Echimyidae is the family of neotropical spiny rats and their fossil relatives. This is the most species-rich family of hystricognath rodents. It is probably also the most ecologically diverse, with members ranging from fully arboreal to terrestrial to fossorial to semiaquatic habits. They presently exist mainly in South America; three members of the family also range into Central America, and the hutias are found in the Greater Antilles in the Caribbean. Species of the extinct subfamily Heteropsomyinae formerly lived on Cuba, Hispaniola, and Puerto Rico in the Antilles, probably until the arrival of Europeans.
Viverravus is an extinct genus of placental mammals from extinct subfamily Viverravinae within extinct family Viverravidae, that lived in North America, Europe and Asia from the middle Paleocene to middle Eocene.
