FUN FACTS

1. Lemurs get their name from the Ancient Roman belief that they were ghosts or spirits. They were mistaken for specters because of their nocturnal, stealth habits.
2. Ruffed lemurs are quadrupedal, using all their limbs for locomotion. Their long tails allow for even better stability in the trees. In fact, most hang upside down, holding on by their feet, when feeding!
3. Lemurs rely on their sense of smell as a way of communicating with other animals. They have special scent glands on their wrists and bottoms that leave scent trails on branches to mark their territories.
4. A lemur's soft, broad fingers and toes have flat nails that allow it to grip objects and groom other lemurs.
5. These prosimians are quite social and the groups have clearly defined male and female hierarchies. Most communities number 2-5 individuals, but can reach up to 16.
6. A female lemur carries her newborn in her mouth until the baby is able to cling to the fur on mother's stomach or back.

ECOLOGY AND CONSERVATION

Lemurs fill an important ecological role of Madagascar. These primates often feed on an assortment of seasonal fruits and as they travel throughout their environment, they disperse undigested seeds in their manure within 2-3 hours. The seeds soon sprout to replenish the vegetation that sustains Madagascar's unique inhabitants. This is very important on an island where over 80% of the original habitats have been lost to logging and agriculture. The Malagasy people struggle to save their country's dwindling biodiversity. They maintain national parks to protect wildlife, support the ecotourism industry, and search for less damaging methods of farming.
