Ring-tailed lemurs, primates characterized by their long striped tails, are known to very social animals. However, with sociality comes aggression. Ring-tailed lemurs have shoulder, wrist & tail glands that secrete a smelly paste. Both before and during fights, males will rub or waft the scent on their territory, or towards their opponent .
