The most striking feature of this subspecies is the stunning cheek ruff of the male, which may range in color from cream to red to off white. Females are, in general, a much drabber brown with a grayish face. In fact, the females of the Sanford’s lemur are difficult to distinguish from the females of the white-fronted lemur. Sanford’s lemurs are sympatric with crowned lemurs throughout most of their range, which is located in the northern tip of Madagascar, and is by far the smallest range of any of the six former brown lemur subspecies. Group size ranges from four to fifteen, with a home range size of up to 14 hectares. Their diet consists of fruit, buds, young and mature leaves, flowers as well as invertebrates (centipedes, millipedes and spiders). This lemur is protected in only three reserves, and although it has been known to survive in secondary forests, populations are probably more endangered than any other brown lemur variety, with the possible exception of the red collared lemur.
