List of mammals of Grenada
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.[1]
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. |
Infraclass: Metatheria
[edit]Order: Didelphimorphia (common opossums)
[edit]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 LC
- Genus: Marmosa
- Subfamily: Didelphinae
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.

Order: Lagomorpha (rabbits and hares)
[edit]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.
