Bemaraha Woolly Lemur
Deep within the rugged landscapes of western Madagascar lives one of the world's most elusive primates: the Bemaraha woolly lemur (Avahi cleesei). Also known as Cleese's woolly lemur, this unique species is a testament to the incredible biodiversity of the region and the ongoing efforts to document and protect rare wildlife.
The species was first recorded in 1990 by a team from Zurich University led by Urs Thalmann. However, it took another fifteen years for the animal to be formally described as a distinct species on November 11, 2005. Interestingly, the lemur was named after John Cleese, the Monty Python star, in recognition of his well-known passion for lemurs and his dedication to their preservation.

Key Facts
- Scientific Name: Avahi cleesei
- Conservation Status: Critically Endangered (IUCN 3.1)
- Protection: Listed under CITES Appendix I
- Habitat: Restricted to the Tsingy de Bemaraha Strict Nature Reserve
- Diet: Strictly vegetarian (leaves and buds)
- Weight: Approximately 5–6 kilograms (11–13 lb)
Physical Characteristics and Appearance
The Bemaraha woolly lemur is a diurnal animal—meaning it is active during the day—with a sturdy, heavyset build. Local populations refer to it as dadintsifaky, which translates to "grandfather of the sifaka." This name stems from the fact that while it is similar in size to the sifaka lemur, it is more ponderous and possesses a thick coat of greyish-brown fur.
Facial Features
The face of A. cleesei is slightly paler than the top of its head. A distinctive triangular pattern is created by the forehead fur, which contrasts with the area above the nose. A black-toned stripe of fur borders the face, forming a shape resembling the letter "V." Its eyes are a striking maroon color with black eyelids, complemented by a black, hairless snout and white tones at the corners of the mouth.
Body and Coat
The primary fur on the head and body is brown-gray with a slightly curled or freckled texture. The tail is beige or brownish-gray, showing a slight reddish tint on the dorsal side of the base. While the chest, belly, and inner upper limbs feature thin, light gray fur, the lower limbs are white.

Habitat and Distribution
The distribution of the Bemaraha woolly lemur is extremely limited. It is found in western Madagascar, specifically near the village of Ambalarano. Its entire known habitat is confined to the Tsingy de Bemaraha Strict Nature Reserve, a UNESCO World Heritage Site renowned for its unique limestone formations.
These lemurs typically live in small family groups, navigating their restricted environment while feeding on a diet consisting exclusively of buds and leaves.
Conservation Status
The Bemaraha woolly lemur is currently classified as Critically Endangered. The species faces a high risk of extinction in the long term due to two primary factors: the continuous shrinkage of its natural habitat and the fact that the exact size of the remaining population remains unknown.
