But the reason I am writing about little buddy the golden bamboo lemur is because it eats primarily the fresh young shoots of the giant bamboo, which are just chock full of cyanide. The word means “before the monkeys.” A prosimian has eyes close to the front of its face, which allows it to see better and be in control of things.

The growing shoots of this bamboo contain 0.015% of cyanide. Madagascar, an island off the southeast coast of Africa, is home to the group of primates known as the lemurs. The giant and grey bamboo lemurs eat from parts of the plant which are very low in cyanide (safe doses like in almonds) or from which cyanide is virtually absent.

The answer is simple: cyanide. viguieri contain 15 mg of cyanide per 100 g of fresh weight. These three sympatric species inhabit the same habitat and feed on the same bamboo species, Cephalostachyum cf viguieri and C. perrieri. Every day, golden bamboo lemurs eat about 500 grams of soft stalks and giant bamboo growing tips, which represents a 12-fold lethal dose of cyanide for most mammals.

The golden bamboo lemur feeds on young shoots, creepers and leaf bases of the endemic giant bamboo (Cephalostachium viguieri) (4), and has evolved to be resistant to the high concentrations of cyanide found within the tissues of this plant (3).Around 500 g of bamboo are eaten every day; this represents roughly 12 times the usual mammalian lethal dose of cyanide (4). The golden bamboo lemur (Hapalemur aureus, Malagasy bokombolomena) is a medium-sized bamboo lemur endemic to south-eastern Madagascar.

Hapalemur aureus Discovered in 1987, critically endangered due to its very specialised diet of Volohosy bamboo leaves, a tree endemic to Madagascar. H. simus prefers the woody pulp and culms of C. cf. The H. griseus stay away from the shoots of this plant because they are highly toxic. This species has been transformed and developed to resist high levels of cyanide, which eat in small amounts of bamboo leaves. [5] The growing shoots of this bamboo contain 0.015% (1 part in 6667) of cyanide. Unfortunately, the mechanism H. aureus uses to detoxify this poison is as yet unknown. viguieri, while H. griseus eats the leaf bases of both species and selects the shoots of C. perrieri. The golden bamboo lemur, Hapalemur aureus was not formally discovered until the ripe old year of 1987 on that beautiful and mysterious island located off the eastern coast of Africa — Madagascar.
