Impossible to confuse with any other species, the ring-tailed lemur has a distinctive long and bushy black-and-white-ringed tail. These medium-sized lemurs move quadrupedally and are the most terrestrial of Madagascar's primates. The back is greyish-brown and the rump and limbs are grey. The underparts are cream and the neck and crown are dark grey. The face is white with large, dark, triangular patches around the eyes. The snout is also dark, but the ears are lighter than the crown. An isolated population in the Andringitra Massif has a slightly different appearance, tending towards darker, redder fur and with fewer black rings on the tail. The taxonomic status of this population has not yet been determined (2).
