Ring tailed lemurs are perhaps the most recognisable lemur species because of their striped black and white tails. They use these for communication and so they can keep track of each other. Other than their tails, they are mostly grey or brown-grey, with white faces and undersides. They also have black rings around their eyes and black muzzles and feet. These lemurs are highly social, being found in large groups. There are multiple males but it is the females that lead the group, with female lineages. Male offspring will leave the group when mature, but female offspring will stay. Females are dominant to males in all aspects. There is a hierarchy between females, but generally older males tend to be dominant in the males. Lemurs are also famous for their “yoga” postures when they sunbathe.
