I LOVE Lemurs! The Lemur exhibit was outside my office when I worked at the zoo! 'A Group'' of Lemurs is just known as a Group, but huddled together they are called 'A Ball of Lemurs' by Keith and Molly's Great Adventure: Ring-tailed Lemurs.
LEMUR- Von der Decken's Sifaka (Propithecus deckenii) is a sifaka native to Madagascar. Today, the Von der Decken's sifaka is listed as Vulnerable, but if habitat destruction continues in Madagascar it won't be long before it's Endangered.
