Lemurs are possibly ancestors of monkeys, possibly a parallel development with them - either way, a primate type unique to Madagascar, where several species are now sadly endangered.

Ring-tailed lemur males sometimes drag their tails over special scent glands on their forearms, and then wave them at each other in so called stink fights. Lemurs also mark their territories with urine; generally smell plays a larger part in their lives than in those of monkeys for whom, like humans, sight is probably the more important sense.

Another unusual feature is that females are dominant and also are permanent members of the group, whereas males, in the wild, have at some point to move off on their own.
