Ruffed lemurs are large primates belonging to the genus Varecia. They are the largest living members of the family Lemuridae.

These animals are found only on the island of Madagascar. They live in the seasonal tropical rainforests of the eastern part of the island. Ruffed lemurs play a vital role in their ecosystem. They help maintain the forest through seed dispersal and pollination.

Because they rely on specific forest types, they are very sensitive to habitat changes.

These primates are diurnal, meaning they are active during the daylight hours. They are also arboreal quadrupeds, which means they move on all four limbs through the trees.

When they leap between branches, they use a specific technique. They launch themselves into the air and twist mid-air. This allows their ventral surface, or belly, to land safely on the new limb. Their long, furry tails help them maintain balance during these movements. The tail is often longer than the body itself. When they are on the ground, they move with bounding hops.

There are two distinct species of ruffed lemurs recognized today. The first is the red ruffed lemur, known scientifically as Varecia rubra.

This species has a very restricted range on the Masoala Peninsula. The second species is the black-and-white ruffed lemur, or Varecia variegata. This species is divided into three subspecies: variegata, editorum, and subcincta.

The black-and-white ruffed lemur has a much larger, though patchy, range across eastern Madagascar. Some populations, like those on Nosy Mangabe, may have been introduced in the 1930s.

Scientists have worked to clarify the history of these animals. In 1962, ruffed lemurs were reassigned to the genus Varecia. This name comes from the Malagasy word "variky."

Previously, they were grouped within the genus Lemur. The evolutionary history of Madagascar's primates is still a subject of debate. It is generally accepted that ancestors arrived via a single rafting event. This likely occurred around 50 to 80 million years ago. They crossed the Mozambique Channel to reach the island. This event allowed them to fill many different ecological niches.

Ruffed lemurs have unique physical traits and reproductive strategies. They have a long, canine-like muzzle with a significant overbite.

They also possess a toothcomb and a toilet-claw on their second toe for grooming.

Their reproductive habits are described as an "evolutionary enigma." Even though they are large, they have short gestation periods of about 102 days. They also have relatively large litter sizes of two to three infants. They are the only primates known to build nests for their newborns. Mothers carry their altricial infants by mouth.

These lemurs are highly frugivorous, meaning they eat mostly fruit. They also consume nectar, which makes them important pollinators.

They are significant pollinators for the traveler's tree. They use their long muzzles to lick nectar from deep inside flowers. As they move, they transfer pollen on their snouts and fur. This relationship is believed to be a result of co-evolution. Furthermore, the seeds they eat pass through their digestive tracts. These seeds are then spread throughout the forest in their feces. This process ensures the growth of new plants.

Today, ruffed lemurs face serious threats from hunting and habitat loss. They are facing extinction in the wild. However, conservation efforts are active. Many organizations, such as the Duke Lemur Center, work to protect them.

Ruffed lemurs reproduce well in captivity. Because of this, they have been gradually re-introduced into the wild since 1997. Protecting the primary forests is essential for their survival. Their presence is a key indicator of a healthy rainforest ecosystem.
