 Males over two years become solitary due to behavioural disposition and collective aggression from the females and will join the female groups only during the breeding season.When provoked, or for defense, coatis can be fierce fighters; their strong jaws, sharp canine teeth, and fast scratching paws, along with a tough hide sturdily attached to the underlying muscles, make it very difficult for potential predators (e.g., dogs or jaguars) to seize the smaller mammal.Coatis communicate their intentions or moods with chirping, snorting, or grunting sounds.
