Does anyone know if the Collared Lemur (Eulemur fulvus collaris) is sexually dimorphic? It is something I should know myself, but I can't remember.
I don't know. But luckily Nick Garbutt's book Mammals of Madagascar is sitting by my computer. Dimorphism is slight, males are brownish-grey above and paler below: females are browner above and creamy-grey below. Both sexes have red-brown cheeks, but those of the males are bushier. Alan
