Ruffed lemurs are a fascinating group of primates found only on the island of Madagascar. These acrobatic, tree-dwelling animals have captivated researchers and conservationists who are working hard to protect these endangered species.

Here are 16 interesting facts about these unique animals:

facts about ruffed lemurs
  1. There are two species of ruffed lemurs: The red ruffed lemur and the black-and-white ruffed lemur. They are classified in the genus Varecia.
  2. Ruffed lemurs get their name from their handsome ruffs: Both species have a ruff of long fur that frames their faces. The black-and-white ruffed lemur has striking coloration with black heads, tails, feet and white bodies.
  3. They are the largest extant lemurs: Ruffed lemurs can grow over four feet long from head to tail and weigh up to 10 pounds. Their tails alone can be over two feet long!
  4. Ruffed lemurs are arboreal and quadrupedal: They move through the forest canopy by running along branches on all fours and making incredible leaps up to 50 feet!
  5. They have special adaptations for living in trees: Long, slender limbs, flexible ankles and wrists, gripping hands and feet, and a long tail they use for balance.
  6. Ruffed lemurs are very vocal: They communicate with a wide variety of sounds including moans, shouts, purrs, grunts and roars. Some of their elaborate songs and choruses help define their territories.
  7. They have a specialized diet of fruit and nectar: Ruffed lemurs have long snouts and tongues with bristly tips that help them get nectar from flowers. They also feast on fruit, especially figs.
  8. Ruffed lemurs are important seed dispersers: By distributing the undigested seeds of their fruit-filled diet, they help regenerate forests across Madagascar.
  9. They live in small family groups: These groups usually contain 2-16 members that share a territory and have complex social interactions.
  10. Ruffed lemurs may breed cooperatively: In some cases, the females of a group may communally nurse and carry each other’s young.
  11. They are seasonal breeders: Mating usually occurs in May or June. After a gestation period of 102-120 days, females give birth to just 1-2 offspring.
  12. Infants are well-developed at birth: they already have fur and open eyes. They begin eating solid food after just 2 weeks and are weaned by 4 months old.
  13. Ruffed lemurs can live over 20 years in captivity: Unfortunately in the wild, their lifespan is shorter at just 15-17 years due to habitat loss and hunting.
  14. Both species are critically endangered: Habitat destruction and hunting have made ruffed lemurs some of the world’s most threatened mammals. Their population has decreased by over 80% in just three generations.
  15. Conservation breeding programs are helping: Organizations like the Duke Lemur Center maintain captive populations under human care while also studying and protecting wild lemurs.
  16. Ecotourism offers hope for their future: By generating revenue from visitors eager to see lemurs surviving in Madagascar’s rainforests, habitat protection efforts can be better funded over the long term.

Ruffed lemurs display incredible athleticism and intelligence as they travel through the forest canopy. These primates play vital ecological roles while exhibiting complex social bonds. Sadly, their future remains uncertain without dedicated conservation efforts. We must act now to preserve these wondrous animals and their forest homes.
