Greater bamboo lemur  (Prolemur simus)

Very little is known about the natural ecology and behaviour of the greater bamboo lemur. Groups composed of 4 to 7 individuals (and occasionally up to 12) have been observed but little else is known about their social structure and interactions (3).

As its common name suggests, this species specialises on eating bamboo, a trait that is highly unusual amongst mammals (5). Almost 98% of the diet is made up of this low-energy food, especially giant bamboo (Cephalostachium viguieri). These lemurs prefer the inner pith of the plant, stripping away the outer layers in a destructive manner (3).
