The term 'ring-tailed mammal' refers to three different species of animals: the raccoon (7 letters), the LEMUR (5 letters), and the COATI (5 letters). Raccoons are native to North America and are known for their distinctive black and white striped tails. Lemurs are primates found on the island of Madagascar, and they have long, bushy tails with alternating black and white rings. Coatis are related to raccoons and are found in Central and South America. They have long, ringed tails that are used for balance when climbing trees.
