This is a list of the mammal species recorded in Grenada. Of the mammal species in Grenada, one is vulnerable and one is considered extinct.This list is derived from the IUCN Red List which lists species of mammals and includes those mammals that have recently been classified as extinct (since 1500 AD). The taxonomy and naming of the individual species is based on those used in existing Wikipedia articles as of 21 May 2007 and supplemented by the common names and taxonomy from the IUCN, Smithsonian Institution, or University of Michigan where no Wikipedia article was available.
The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: EX Extinct No reasonable doubt that the last individual has died. EW Extinct in the wild Known only to survive in captivity or as a naturalized populations well outside its previous range. CR Critically endangered The species is in imminent risk of extinction in the wild. EN Endangered The species is facing an extremely high risk of extinction in the wild. VU Vulnerable The species is facing a high risk of extinction in the wild. NT Near threatened The species does not meet any of the criteria that would categorise it as risking extinction but it is likely to do so in the future. LC Least concern There are no current identifiable risks to the species. DD Data deficient There is inadequate information to make an assessment of the risks to this species.
Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of near threatened and least concern categories: LR/cd Lower risk/conservation dependent Species which were the focus of conservation programmes and may have moved into a higher risk category if that programme was discontinued. LR/nt Lower risk/near threatened Species which are close to being classified as vulnerable but are not the subject of conservation programmes. LR/lc Lower risk/least concern Species for which there are no identifiable risks.
Subclass: Theria
Infraclass: Metatheria
Order: Didelphimorphia (common opossums)
Didelphimorphia is the order of common opossums of the Western Hemisphere. Opossums probably diverged from the basic South American marsupials in the late Cretaceous or early Paleocene. They are small to medium-sized marsupials, about the size of a large house cat, with a long snout and prehensile tail.
Family: Didelphidae (American opossums) Subfamily: Didelphinae Genus: Marmosa Robinson's mouse opossum, M. robinsoni
Infraclass: Eutheria
Order: Sirenia (manatees and dugongs)
Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered.
Family: Trichechidae Genus: Trichechus West Indian manatee, T. manatus extirpated
Order: Rodentia (rodents) Rodentia is an order of mammals characterised by two continuously growing incisors in the upper and lower jaws which must be kept short by gnawing. Family: Cricetidae Genus: Megalomys Grenada giant rice rat, M. camerhogne Family: Dasyproctidae Genus: Dasyprocta Red-rumped agouti, D. leporina introduced
Order: Primates The order Primates includes the lemurs, monkeys, and apes, with the latter category including humans.
Family: Cercopithecidae Genus: Cercopithecus Mona monkey, C. mona introduced
Order: Cingulata (armadillos)
The armadillos are small mammals with a bony armored shell. There are around 20 extant species. They are native to the Americas.
Family: Dasypodidae (armadillos) Subfamily: Dasypodinae Genus: Dasypus Nine-banded armadillo, D. novemcinctus
Order: Lagomorpha (rabbits and hares) The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas). Though they can resemble rodents, and were classified as a superfamily in that order until the early 20th century, they have since been considered a separate order. They differ from rodents in a number of physical characteristics, such as having four incisors in the upper jaw rather than two.
Family: Leporidae Genus: Lepus European hare, L. europaeus introduced
Order: Chiroptera (bats) The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight. Bat species account for about 20% of all mammals.
Family: Noctilionidae Genus: Noctilio Greater bulldog bat, N. leporinus Family: Vespertilionidae Subfamily: Myotinae Genus: Myotis Black myotis, M. nigricans Myotis nyctor Family: Emballonuridae Genus: Peropteryx Lesser doglike bat, P. macrotis Trinidad dog-like bat, P. trinitatis Family: Mormoopidae Genus: Pteronotus Naked-backed bat, P. davyi Family: Phyllostomidae Subfamily: Phyllostominae Genus: Dermanura Silver fruit-eating bat, D. glauca Genus: Micronycteris Little big-eared bat, M. megalotis Subfamily: Glossophaginae Genus: Anoura Geoffroy's tailless bat, A. geoffroyi Genus: Glossophaga Miller's long-tongued bat, G. longirostris Subfamily: Carolliinae Genus: Carollia Seba's short-tailed bat, C. perspicillata Subfamily: Stenodermatinae Genus: Artibeus Jamaican fruit bat, A. jamaicensis Great fruit-eating bat, A. lituratus A. schwartzi
Order: Cetacea (whales)
The order Cetacea includes whales, dolphins and porpoises. They are the mammals most fully 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.
Suborder: Mysticeti Family: Balaenopteridae (baleen whales) Genus: Balaenoptera Common minke whale, Balaenoptera acutorostrata Sei whale, Balaenoptera borealis Bryde's whale, Balaenoptera brydei Blue whale, Balaenoptera musculus Genus: Megaptera Humpback whale, Megaptera novaeangliae Suborder: Odontoceti Superfamily: Platanistoidea Family: Delphinidae (marine dolphins) Genus: Delphinus Short-beaked common dolphin, Delphinus delphis DD Genus: Feresa Pygmy killer whale, Feresa attenuata DD Genus: Globicephala Short-finned pilot whale, Globicephala macrorhyncus DD Genus: Lagenodelphis Fraser's dolphin, Lagenodelphis hosei DD Genus: Grampus Risso's dolphin, Grampus griseus DD Genus: Orcinus Killer whale, Orcinus orca DD Genus: Peponocephala Melon-headed whale, Peponocephala electra DD Genus: Pseudorca False killer whale, Pseudorca crassidens DD Genus: Sotalia Guiana dolphin, Sotalia guianensis DD Genus: Stenella Pantropical spotted dolphin, Stenella attenuata DD Clymene dolphin, Stenella clymene DD Striped dolphin, Stenella coeruleoalba DD Atlantic spotted dolphin, Stenella frontalis DD Spinner dolphin, Stenella longirostris DD Genus: Steno Rough-toothed dolphin, Steno bredanensis DD Genus: Tursiops Common bottlenose dolphin, Tursiops truncatus Family: Physeteridae (sperm whales) Genus: Physeter Sperm whale, Physeter catodon DD Family: Kogiidae (dwarf sperm whales) Genus: Kogia Pygmy sperm whale, Kogia breviceps DD Dwarf sperm whale, Kogia sima DD Superfamily Ziphioidea Family: Ziphidae (beaked whales) Genus: Mesoplodon Gervais' beaked whale, Mesoplodon europaeus DD Genus: Ziphius Cuvier's beaked whale, Ziphius cavirostris DD
