With fewer than a thousand individuals remaining in the wild, the Critically Endangered Golden Bamboo Lemur (Hapalemur aureus) holds on to a tenuous existence in the rainforests of Madagascar. It’s discovery in the mid-1980’s was a crucial factor that led to the foundation of the now famous Ranomafana National Park – a reserve that protects over 400 sq. km. of tropical forest. Like other bamboo lemurs, it feeds primarily on bamboo shoots which, due to their high cyanide content, are lethally toxic to most other animals. Ranomafana National Park, Madagascar.
