The Cozumel coati (Nasua narica nelsoni), or Cozumel Island coati, is a coati from the Mexican island of Cozumel, in the Caribbean Sea. It is in the family Procyonidae, which also includes raccoons, olingos, and kinkajous.
It has been treated as a species, but the vast majority of recent authorities treat it as a subspecies of the white-nosed coati. [1] [2] [3] [4] Cozumel Island coatis are slightly smaller than the white-nosed coatis of the adjacent mainland (N. n. yucatanica); but, when compared more widely to white-nosed coatis, the difference in size is not as clear. [5] The level of other differences also support its status as a subspecies rather than a separate species. [5]
It has been speculated that it is the result of an ancient introduction to Cozumel by the Mayans. [6] Although not rated by the IUCN (where included in the widespread white-nosed coati), [4] it is believed that the Cozumel Island coati is highly threatened and close to extinction. [7]
The white-nosed coati, also known as the coatimundi, is a species of coati and a member of the family Procyonidae. Local Spanish names for the species include antoon, gato solo, pizote, and tejón, depending upon the region. It weighs about 4–6 kg (8.8–13.2 lb), and the nose-to-tail length of the species is about 110 cm (3.6 ft) with about half of that being the tail length. However, small females can weigh as little as 3.1 kg (6.8 lb), while large males can weigh as much as 9 kg (20 lb).
Coatis, also known as coatimundis, are members of the family Procyonidae in the genera Nasua and Nasuella. They are diurnal mammals native to South America, Central America, Mexico, and the Southwestern United States. The name "coatimundi" comes from the Tupian languages of Brazil, where it means "lone coati". Locally in Belize, the coati is known as "quash".
Procyonidae is a New World family of the order Carnivora. It includes the raccoons, ringtails, cacomistles, coatis, kinkajous, olingos, and olinguitos. Procyonids inhabit a wide range of environments and are generally omnivorous.
The kinkajou is a tropical rainforest mammal of the family Procyonidae related to olingos, coatis, raccoons, and the ringtail and cacomistle. It is the only member of the genus Potos and is also known as the "honey bear". Though kinkajous are arboreal, they are not closely related to any other tree-dwelling mammal group.
Urocyon is a genus of Canidae which includes the gray fox and the island fox. These two fox species are found in the Western Hemisphere. Whole genome sequencing indicates that Urocyon is the most basal genus of the living canids. Fossils of what is believed to be the ancestor of the gray fox, Urocyon progressus, have been found in Kansas and date to the Upper Pliocene, with some undescribed specimens dating even older.
Nasua is a genus of coatis of the family Procyonidae. Two additional species of coatis, commonly known as mountain coatis, are placed in the genus Nasuella.
Mountain coatis are two species of procyonid mammals from the genus Nasuella. Unlike the larger coatis from the genus Nasua, mountain coatis only weigh 1.0–1.5 kilograms (2.2–3.3 lb) and are endemic to the north Andean highlands in South America.
The western mountain coati or western dwarf coati is a small procyonid, found in cloud forest and páramo at altitudes of 1,300–4,250 metres (4,270–13,940 ft) in the Andes of Colombia and Ecuador. A population discovered in the Apurímac–Cuzco region of southern Peru has tentatively been identified as the western mountain coati, but may represent an undescribed taxon.
The Tres Marias raccoon is a subspecies of the common raccoon endemic on the two main islands of the Islas Marías, an archipelago off the western coast of the Mexican state of Nayarit. Although sometimes considered to be a valid species, the Tres Marias raccoon is now regarded to be a subspecies of the common raccoon, introduced to the Islas Marías in the recent past. It is slightly larger than the common raccoon and has a distinctive angular skull. There are fewer than 250 mature individuals on the islands, they are hunted by the islanders and the International Union for Conservation of Nature has rated their conservation status as being "endangered".
Dwarf coati can refer to several species:
The South American coati, also known as the ring-tailed coati, is a coati species and a member of the raccoon family (Procyonidae), found in the tropical and subtropical parts of South America. An adult generally weighs from 2–7.2 kg (4.4–15.9 lb) and is 85–113 cm (33–44 in) long, with half of that being its tail. Its color is highly variable and the rings on the tail may be only somewhat visible, but its most distinguishing characteristic is that it lacks the largely white snout of its northern relative, the white-nosed coati.
The Cozumel raccoon is a critically endangered species of island raccoon endemic on Cozumel Island off the coast of the Yucatan Peninsula, Mexico. It is sometimes also called the pygmy raccoon, dwarf raccoon, Cozumel Island raccoon, and Cozumel raccoon bear.
The Cozumel harvest mouse is a species of rodent in the family Cricetidae. It is endemic to the Mexican island of Cozumel off the Yucatán Peninsula. It is nocturnal and semiarboreal, and lives in dense secondary forest and forest edge habitats. Its population is small, fluctuating and patchily distributed. The species is threatened by predation from feral cats and dogs and introduced boa constrictors, by competition with introduced nonnative rats and mice, and by habitat disturbances caused by hurricanes and floods which periodically strike the island.
The common brown lemur is a species of lemur in the family Lemuridae. It is found in Madagascar and has been introduced to Mayotte.
The term island raccoons is used as a generic term for four endangered and one extinct subspecies or species of raccoon (Procyon) endemic on small Mexican and Caribbean islands, such as Cozumel and Guadeloupe. Other subspecies of raccoon living on islands, like that of the common raccoon native to the Florida Keys, are generally not included under this term, since it was established at a time when all five "island raccoons" were considered distinct species. The five populations are:
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.
The eastern mountain coati or eastern dwarf coati is a small procyonid found in cloud forest and páramo at elevations of 2,000–4,000 m (6,600–13,100 ft) in the Andes of western Venezuela. Until 2009, it was included as a subspecies of the western mountain coati, but the eastern mountain coati is overall smaller, somewhat shorter-tailed on average, has markedly smaller teeth, a paler olive-brown pelage, and usually a dark mid-dorsal stripe on the back versus more rufescent or blackish, and usually without a dark mid-dorsal stripe in the western mountain coati. When the two were combined, they were classified as Data Deficient on the IUCN Red List but following the split the eastern mountain coati is considered endangered. A genetic analysis revealed that it should be regarded as a synonym of N. olivacea.
