46. Red Ruffed Lemur

Varecia rubra

About

The red ruffed lemur is one of the largest species of lemur.

Red ruffed lemurs’ live on the east coast of Madagascar, in almost overlapping ranges with its sister species the black and white ruffed lemur. Despite living in separate ranges, and being separate species the two can understand each other’s calls and communications.

The two species are the only members of their genus Varecia and are both critically endangered. Lemurs are part of a group of the most basal living primates, and have evolved independently on Madagascar for 50-60 million years.

The red ruffed lemur lives in small matriarchal (female lead) groups of 2-16, but group sizes of 32 have been recorded. Because of its large size, it has a larger range size, and is therefore more acutely under threat from habitat destruction by logging, burning of habitat, cyclones and mining. And again, because of its size, it is prone to the threat of humans hunting it for food; as well as for capture into the illegal pet trade.

The size of each word indicates the extent of a species range that is affected by that threat (larger size means a greater area is affected). The colour of the word indicates how much that threat impacts the species (darker shades of red mean the threat is more severe).
