Unlike most other lemurs, all but one species of lemurid ( the Ring-tailed Lemur ) lack a tapetum lucidum, a reflective layer in the eye that improves night vision.

In some cases, such as the Ring-tailed Lemur, the groups are long-lasting, with distinct dominance hierarchies, while in others, such as the Common Brown Lemur, the membership of the groups varies from day to day, and seems to have no clear social structure.

This family was once broken into two subfamilies, Hapalemurinae ( bamboo lemurs and the Greater Bamboo Lemur ) and Lemurinae ( the rest of the family ), but molecular evidence and scent glands similarities have since placed the Ring-tailed Lemur with the bamboo lemurs and the Greater Bamboo Lemur.

Species included are Allen's Swamp Monkey, Coquerel's Sifaka, Golden-headed Lion Tamarin, Lion-tailed Macaque, Pygmy Marmoset, Ring-tailed Lemur, and White-faced Saki.

Also in a throwback gesture, in A Fish Called Wanda there was a fish named after Jamie Lee Curtis ' character ; in Fierce Creatures there is a Ring-tailed Lemur named after Cleese's character.
