93. Claire’s Mouse Lemur

Microcebus mamiratra


Very little is known about Claire’s mouse lemur which is only found on Nosy Bé Island, Madagascar, in a very restricted and fragmented area, and are in decline due to habitat loss and degradation.

Lemurs belong to the suborder Strepsirhini, which also includes bushbabies, pottos and lorises. These groups are the most basal living primates and are characterised by their ‘wet’ noses. Ancestral prosimians, possibly resembling today’s mouse lemurs, are thought to have colonised Madagascar from mainland Africa 50-60 million years ago. In the absence of competition from other non-primate mammals, these species diversified to fill a wide range of unusual ecological niches.

  • Order: Primates
  • Family: Cheirogaleidae
