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 .
Nasua differs from Nasuella in being larger and having larger canine teeth, [2] but preliminary genetic evidence (cytochrome b sequences) suggests that Nasuella should be merged into Nasua. [3] Other genetic studies have shown that the closest relatives of the coatis are the olingos (genus Bassaricyon), [4] [5] [6] from which they diverged about 10.2 million years ago. [6]
Like other procyonids, [7] coatis are omnivores. Their diet consists largely of insects (including their larvae), spiders and other invertebrates as well as the occasional small vertebrate discovered while energetically foraging, with their sensitive noses to the ground, in forest leaf litter. On Barro Colorado Island, Panama, where they have been studied in greatest detail, [8] [9] they supplement this diet with copious amounts of fruit as it becomes available seasonally from favored trees, such as figs ( Ficus insipida ) and hog plums ( Spondias mombin ).
Their very active foraging behavior appears to be interrelated with their distinctive social organization. Exceptional among procyonids, coatis are diurnal and for much of the year gregarious. Though females nest, and bear and nurse their young in isolation, shortly after the altricial young become mobile the females aggregate into social groups known as bands. Bands consist of adult females (two or more years old), and sub-adults (1–2 years old) and juveniles (less than 1 year old) of both sexes. At maturity, at two years of age, males are excluded from bands and take up a solitary lifestyle. They are aggressively repelled from bands, except during the mating season when typically one male ingratiates himself to a band through submissive behavior, forages with it for a period of a few weeks, and mates with all of the adult females. During the nesting season, the sub-adults and juveniles remain together in bands while breeding adult females become solitary for parturition and nesting. Females begin breeding in their 3rd or 4th year, apparently depending on nutritional status. Occasionally, older females become postreproductive, and these remain with the bands while breeding females separate. Breeding is synchronous, as is parturition and nursing. Resumption of gregarious behavior takes place synchronously as well, over the course of several weeks, depending on the existence of previous social relationships, i.e. females with prior relationships reaggregate into bands more quickly than those forming new relationships. Nonetheless, persistent social bonds may form anew at this point in the reproductive cycle: while there may be a tendency to reaggregate with kin, prior relationships are not indispensable. Previously unfamiliar individuals may aggregate into bands with stable social relationships. A conspicuous means of bond formation is mutual grooming, on which an hour or more may be spent daily. Some of this appears to be ritualized as a form of social bond formation (Fig. 1), though it is clearly mutually beneficial as well: the burden of ticks on band members is lower than it is on solitary adult males, for instance. [10]
When juveniles descend from the nest, they are little better than helpless. One important benefit of aggregating for the adult females is sharing of vigilance in protection of juveniles from predation. Juvenile mortality is high, sources of peril including adult male coatis which have been observed to kill them. [11] It is not entirely clear whether adult males are preying on them or killing potential rivals, and of course it may be both.
The active foraging behavior of coatis is fairly conspicuous, and requires a considerable degree of attention. The proportion of time that adult females spend foraging increases, and the proportion of foraging time interrupted for stationary vigilance behavior decreases, when aggregation into bands is achieved. Bands forage in formation, with adults and sub-adults distributed around the periphery, and juveniles gathered towards the center. This shared vigilance appears to be an important contributor to the benefit of gregariousness for coatis.
The two species within Nasua are:
| Image | Scientific name | Common Name | Distribution |
|---|---|---|---|
 | N. narica (Linnaeus, 1766) | white-nosed coati, pizote, or antoon | Southwestern United States (southern New Mexico, Arizona, but no longer Texas), Mexico, Central America, and northwest Colombia. [12] [13] |
 | N. nasua (Linnaeus, 1766) | South American coati | South America |
DNA sequence analysis indicates that the N. narica and N. nasua lineages split about 5.6 million years ago. [6]
The Cozumel Island coati had been recognized as a third species, but the vast majority of recent authorities treat it as a subspecies, N. narica nelsoni, of the white-nosed coati. [1] [14] [15] [16] [17]

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 pizote, antoon, 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 comprises the raccoons, ringtails, cacomistles, coatis, kinkajous, olingos, and olinguitos. Procyonids inhabit a wide range of environments and are generally omnivorous.
Procyon is a genus of nocturnal mammals comprising three species commonly known as raccoons in the family Procyonidae. The most familiar species, the common raccoon, is often known simply as "the" raccoon, as the two other raccoon species in the genus are native only to the tropics and less well known. Genetic studies have shown that the closest relatives of raccoons are the ring-tailed cats and cacomistles of genus Bassariscus, from which they diverged about 10 million years ago.
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". Kinkajous are arboreal, a lifestyle they evolved independently; they are not closely related to any other tree-dwelling mammal group.
The pottos are three species of strepsirrhine primate in the genus Perodicticus of the family Lorisidae. In some English-speaking parts of Africa, they are called "softly-softlys".
Bassariscus is a genus in the family Procyonidae. There are two extant species in the genus: the ringtail or ring-tailed cat and the cacomistle. Genetic studies have indicated that the closest relatives of Bassariscus are raccoons, from which they diverged about 10 million years ago in the Tortonian Age of the Miocene. The two lineages of Bassariscus are thought to have separated after only another two million years, making it the extant procyonid genus with the earliest diversification. Later diversification in the genus in the Pliocene and Pleistocene saw the emergence of two extinct species, Bassariscus casei and Bassariscus sonoitensis, respectively. Due to the more digitigrade stance of their legs compared to the plantigrade stance of other members of Procyonidae, some taxonomies place the genus as a separate family, Bassaricidae.. The name is a Greek word for fox ("bassaris") with a Latinized diminutive ending ("-iscus"). The genus was named by Elliott Coues in 1887, having previously been described by Lichtenstein in 1830 under the name Bassaris. Coues proposed the word "bassarisk" as the English term for animals in this genus. Its habitat includes semi-arid areas in the southwestern United States, the whole of Mexico, as well as moist tropical forests in Central America.
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.
Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs, bears, raccoons, and mustelids. The Pinnipedia are also assigned to this group. The center of diversification for the Caniformia is North America and northern Eurasia. Caniformia stands in contrast to the other suborder of Carnivora, the Feliformia, the center of diversification of which was in Africa and southern Asia.
The black caiman is a crocodilian reptile endemic to South America. With a maximal length of 5 to 6 m and a mass of over 450 kg (1,000 lb), it is the largest species of the family Alligatoridae and the third largest in the Neotropical realm. Like what its common and scientific names implies, the black caiman has a dark coloration as an adult. In some individuals, the dark coloration can appear almost black. It has grey to brown banding on the lower jaw. Juveniles have a more vibrant coloration compared to adults with prominent white to pale yellow banding on the flanks that remains present well into adulthood, at least more when compared to other species. The morphology is quite different from other caimans but the bony ridge that occurs in other caimans is present. The head is large and heavy, an advantage in catching larger prey. Like all crocodile-like animals, caimans are long, squat creatures, with big jaws, long tails and short legs. They have thick, scaled skin, and their eyes and noses are located on the tops of their heads. This enables them to see and breathe while the rest of their bodies are underwater.
The genus Bassaricyon consists of small Neotropical procyonids, popularly known as olingos, cousins of the raccoon. They are native to the rainforests of Central and South America from Nicaragua to Peru. They are arboreal and nocturnal, and live at elevations from sea level to 2,750 m. Olingos closely resemble another procyonid, the kinkajou, in morphology and habits, though they lack prehensile tails and extrudable tongues, have more extended muzzles, and possess anal scent glands. However, the two genera are not sisters. They also resemble galagos and certain lemurs.
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 northern olingo, also known as the bushy-tailed olingo or as simply the olingo, is a tree-dwelling member of the family Procyonidae, which also includes raccoons. It was the first species of olingo to be described, and while it is considered by some authors to be the only genuine olingo species, a recent review of the genus Bassaricyon has shown that there are a total of four olingo species, although two of the former species should now be considered as a part of this species. Its scientific name honors William More Gabb, who collected the first specimen. It is native to Central America.
The Cozumel coati, 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.
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 also called the pygmy raccoon, dwarf raccoon, Cozumel Island raccoon, and Cozumel raccoon bear.
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.
The olinguito is a mammal of the raccoon family Procyonidae that lives in montane forests in the Andes of western Colombia and Ecuador. It was classified as belonging to a new species in 2013. The specific name neblina is Spanish for fog or mist, referring to the cloud forest habitat of the olinguito.
