This includes the ring-tailed lemur with its furry, striped tail, the dancing sifakas that leap sideways through the trees, and the goblin-like nocturnal aye-aye which uses its long middle finger to dig for food.
Subfossil discoveries of extinct lemur species tell us there was even greater diversity before. It is believed that one extinct lemur species was the size of a gorilla! Hunting may have led to the extinction of this and other species after the arrival of humans on the island approximately 2, years ago. Ring-tailed lemurs at Duisburg. Photo: Mathias Appel. Lemurs are a diverse group of primates, but share several common traits.
These traits distinguish them from other types of primates, like monkeys and apes. What are their unique characteristics?
Lemurs communicate in various ways, but their sense of smell is particularly unique. Compared to many other primates, they have longer snouts and wet noses that help them communicate with smell. Lemurs also use vision less primarily than other primates. But, they do have improved night vision due to the retained extra layer of tissue behind the retina in the eye. This is called the tapetum lucidum.
The fact that lemurs have improved night vision indicates that their ancestors were likely nocturnal. Lemurs have forward leaning rather than upward incisors and canine teeth. This is called a toothcomb and is seen in all existing lemur species except the aye-aye. Ring-tailed lemurs live in groups known as troops. These groups may include 6 to 30 animals, but average about Both sexes live in troops, but a dominant female presides over all. Ring-tailed lemurs are threatened, largely because the sparse, dry forests they love are quickly vanishing.

Expert view: Oliver Greenfield Officially the dry season runs from April - October although due to the size and geography of the island there are various regional weather variations.
Many have large populations remaining whereas others are very near extinction in the wild. They are all considered endangered. It depends on the species. Ring Tailed lemur Easily recognisable by their banded tails and dark, mask like eyes, ring tailed lemurs inhabit dry scrub, deciduous and gallery forests in the south and southwest of the island.
Black Lemur Males are all black and females have a brown back, a grey head, long white ear tufts and are white underneath. Red Ruffed lemur One of the largest primates in Madagascar, these lemurs are restricted to Masoala Peninsula in the northeast.
Verreaux's Sifaka Also known as white sifakas, they belong to the same family as the indri. Indri These are the largest of the lemurs, known for their strange wailing song and teddy bear like appearance. Bamboo Lemur Living in small groups of up to four, they feed mainly on bamboo. The golden bamboo lemur, however, is much rarer and mainly seen in Ranomafana National Park Mouse Lemur This abundant species can be found throughout Madagascar and most easily seen in Ranomafana and Andasibe National Parks as well as the Berenty Reserve.
Aye Aye Despite being quite well spread, these eerie looking, solitary creatures are rarely seen.
