Omnivorous arboreal mammal with characteristic long banded tail and long snout. Similar size to a small dog. Coat colour ranges from orangish/reddish to dark brown (Gompper & Decker, 1998). Snout, feet and ears are dark brown or black. Weighs approximately 5.5kg (NNSS, undated.)
A generalist opportunistic omnivore, their diet is mainly made up of insects and fruit (Gompper & Decker, 1998). They are a human commensal and will predate domestic poultry (Baker, 2011) and consume human refuse (Gompper & Decker, 1998). They will also eat birds’ eggs and may compete for nest sites (European Commission, 2015). Their presence is associated with a decrease in biodiversity with potential effects on native fauna and endangered species as with the Majorcan midwife toad (Alytes muletensis) (European Commission, 2017). Nasua narica is known for crop raiding decreasing crop productivity and this may be an impact of N. nasua establishment (European Commission, 2015). Carriers of rabies, tuberculosis, canine and feline distemper, parvovirus and leptospirosis. Diurnal and can be arboreal (European Commission, 2015).
Adult males are solitary only joining the females briefly during the breeding season (AZA, 2010). Females and young live in social groups called 'bands' (Marchant, 2012). Males and females reach sexual maturity at approximately 2 years of age (AZA, 2010; Gompper & Decker, 1998). They are seasonal breeders producing 2-7 young after a 72 – 77 day gestation (AZA, 2010). Females build nests in trees where the young remain for 5-6 weeks. The young are weaned by 4 months (AZA, 2010; Gompper & Decker, 1998).
Pathway and vector description
The main pathway is escape form zoos, wildlife/private collections or deliberate introductions/release (Baker, 2011). Available for purchase on the internet in Europe (Baker, 2011). Natural populations can then establish from small numbers of founder animals (European Commission, 2015). Spread from there is via natural dispersal and they may cover long distances when searching for food (Marchant, 2012).
Mechanism of impact
Predation, Disease transmission
There is currently an EU wide ban on the sale of this species and personal and zoo ownership is being phased out (European Commission, 2017).
Little information is available on the control of this species. However, they are elusive making management difficult and there are few possible predators of this species in Europe (European Commission, 2015).
Hirsch (2015) suggests similar methods of control as for raccoons (Procyon lotor). Control of these is usually achieved by live trapping or shooting.
Early detection and rapid eradication seems critical in preventing establishment of this species.
Forested areas, grassland, savannah as well as dry scrub land. Will live in close proximity to humans (Gompper & Decker, 1998).
Introduced species in Robinson Crusoe Island (Chile), Majorca, Anchiete Island (Brazil) and in Florida. Countries considered to be at risk of establishment in Europe are France, Greece, Italy and Portugal, (European Commission, 2015).
Argentina, Bolivia, Columbia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay, Venezuela, Mexico (Marchant, 2012).

The species survived during the winter in the Lake District in the UK for some time but the risk assessment carried out for the UK by Baker (2011) summarises establishment as unlikely.
The coati is sometimes referred to as coatimundi. This name comes from the local people’s name for the solitary male coati (Gompper & Decker, 1998).
