life science Maturity 5-7 Next article →

Coatis are clever mammals belonging to the family Procyonidae. This family includes other well-known animals like raccoons and kinkajous.

The name coati comes from Tupian Indian languages. In Brazil, the name "coatimundi" means "lone coati." In Belize, these animals are known locally as "quash." Coatis are widespread across many different environments. They live in habitats ranging from hot, arid lands to humid Amazonian rainforests. They can even survive on cold Andean mountain slopes. Their range extends from the southwestern United States through northern Uruguay.

Coatis have very specific physical traits that help them survive. They have slender heads with long, flexible snouts. This snout can rotate up to 60 degrees in any direction. Because of this, they are often called "hog-nosed raccoons." They use their noses to push objects and find food.

Coatis are plantigrade, which means they walk on the soles of their feet like humans. They have nonretractable claws for digging and climbing. A very special feature is their ankles. Coatis can rotate their ankles beyond 180 degrees. This unique ability allows them to descend trees head first.

These animals have different ways of living together. Most coatis are diurnal, meaning they are active during the day. This is different from their nocturnal relatives, the raccoons. Females and young males are gregarious, which means they live in social groups. These groups are called bands and can have four to 25 individuals. Adult males are usually solitary. They only join the female bands during the breeding season.

Coatis use many sounds to communicate. They use chirping to show joy or irritation. They use snorting to claim food or territory. They also use body language, such as hiding their nose between their paws to show submission.

Scientists categorize coatis into two main genera: Nasua and Nasuella. The genus Nasua includes the white-nosed coati and the South American coati. Linnaeus named both of these species in 1766. The genus Nasuella includes the mountain coatis. The eastern mountain coati was named by Thomas in 1901. The western mountain coati was named by Gray in 1865.

While most authorities see the Cozumel Island coati as a subspecies, some scientists have studied its unique status. Genetic evidence suggests that the Nasuella genus might eventually be merged into Nasua.

Coatis are omnivores, so they eat a wide variety of foods. Their diet mainly consists of fruit and ground litter. They also hunt invertebrates, such as tarantulas.

They will even eat small vertebrates like lizards, rodents, and birds. They are known to eat bird eggs and even crocodile eggs. Their strong jaws and sharp canine teeth help them defend themselves. Their tough hide is also firmly attached to their muscles. This makes it difficult for predators like jaguars or pumas to grab them.

Reproduction in coatis is timed with the environment. The breeding season usually starts with the rainy season. This ensures there is plenty of food, especially fruit, for the young. Pregnant females separate from their bands to build nests. These nests are located in trees or rocky niches. After a gestation period of about 11 weeks, they give birth to litters. A single litter can have between three and seven kits.

About six weeks after birth, the mothers and kits rejoin the larger band.

In the wild, coatis face many different predators. These include large cats like ocelots, pumas, and jaguars. They are also hunted by snakes like anacondas and boa constrictors. Even large birds, such as harpy eagles, can hunt them.

In Central and South America, coatis are threatened by hunting and habitat destruction. Some coatis are also kept as pets in various parts of the Americas. In captivity, they can live much longer than in the wild. While wild coatis live up to seven years, captive coatis can live into their late teens.
