# List of mammals of the Cayman Islands

This is a list of the mammal species recorded in the Cayman Islands. There are the mammal species in the Cayman Islands, of which one is believed to be threatened.
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. |

## Subclass: Theria
### 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 VU

#### 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.

#### 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. Rodents make up 40% of mammal species, and they are found in vast numbers on all continents other than Antarctica. Rodents have sharp incisors that they use to gnaw wood, break into food, and bite predators. Most eat seeds or plants, though some have more varied diets. Some species have historically been pests, eating seeds stored by people and spreading disease.
The name comes from the Latin word rodens, "gnawing one" (from the verb rodere, "gnaw").
In terms of number of species—although not necessarily in terms of number of organisms (population) or biomass—rodents make up the largest order of mammals. There are about 2,277 species of rodents (Wilson and Reeder, 2005), with over 40% of mammalian species belonging to the order.
The Central American agouti has been introduced to the Cayman Islands, and are found in forests, thick brush, savannas, and cultivated areas.
