Lemurs are a special type of primate called prosimians, which are the oldest group of primates. The golden bamboo lemur, apparently tolerant of high concentrations of cyanide, eats the cyanide containing leaf bases, shoots, and piths of new-growth giant bamboo. The growing shoots of this bamboo contain 0.015% (1 part in 6667) of cyanide. Lemurs that go out to hunt only … 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 growing tips of Cephalostachyum ef uiguieri selected by the golden bamboo lemur (Hapalemuraureus) contained 15 mg of cyanide per 100 g fresh weight bamboo while the leaves of C. perrieri selected by the gentle bamboo lemur (H. griseus)and the mature culms of C. cf uiguieri selected by the greater bamboolemur (H. simus) did not contain cyanide. The golden bamboo lemur is so called because of the golden fur around its face, inner limbs and belly. See more » Cyanide.

Unique to Madagascar, these animals are thought to resemble the primitive ancestor of today's monkeys and apes. Hapalemur aureus Discovered in 1987, critically endangered due to its very specialised diet of Volohosy bamboo leaves, a tree endemic to Madagascar. If the forest is damaged by fire or trees are cut, other faster imported tree species like eucalyptus will grow, leaving no space for new Volohosy trees.

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. is most active at dawn and dusk. In the 1 pound of bamboo that golden bamboo lemurs eat daily, they consequently consume twelve times the lethal dose of cyanide in comparable mammals. Madagascar, an island off the southeast coast of Africa, is home to the group of primates known as the lemurs. The population is declining, predominantly due to hunting and to ongoing habitat loss; with only about 1,000 individuals remaining. How then is major competition avoided? The park was opened in 1991 to protect this endangered lemur, as well as several other lemur species and its flora and fauna. Each adult lemur eats about 500 g (18 oz) of bamboo per day, which contain about twelve times the lethal dose of cyanide for most other animals of this size. These three sympatric species inhabit the same habitat and feed on the same bamboo species, Cephalostachyum cf viguieri and C. perrieri.

A cyanide is a chemical compound that contains the group C≡N. The golden bamboo lemur (Hapalemur aureus, Malagasy bokombolomena) is a medium-sized bamboo lemur endemic to south-eastern Madagascar. How bamboo lemurs can detoxify the high amounts of cyanide (from bamboo shoots) in their diets is unknown. Among these are the genus Hapalemur or the Bamboo lemurs. The amount of cyanide consumed daily by this species is enough to kill three men. [6][4], They live in small groups of two to six individuals and have a home range of up to 80 hectares (0.31 sq mi). The growing tips of Cephalostachyum ef uiguieri selected by the golden bamboo lemur (Hapalemuraureus) contained 15 mg of cyanide per 100 g fresh weight bamboo while the leaves of C. perrieri selected by the gentle bamboo lemur (H. griseus)and the mature culms of C. cf uiguieri selected by the greater bamboolemur (H. simus) did not contain cyanide.

Golden bamboo lemur (Hapalemur aureus) male eating a poisonous (but not to him), cyanide-containing bamboo shoot in rainforest. 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. Unfortunately, the mechanism H. aureus uses to detoxify this poison is as yet unknown. This species has been transformed and developed to resist high levels of cyanide, which eat in small amounts of bamboo leaves. New!!

Bamboo lemurs are a genus of 5 species, and are the only primates in the world that specialise on a bamboo diet. The park was created in 1991. The Golden bamboo lemur has evolved with a resistance to the extreme levels of cyanide in the leaves of the young bamboo that it eats. H. aureus meanwhile eats only the shoots of C. cf. The principal loss of habitat is due to slash-and-burn agriculture or the harvesting of bamboo, for use as a building material as well as for carrying water and basket making. Each adult lemur eats about 500 g (18 oz) of bamboo per day, which contain about 12 times the lethal dose of cyanide for most other animals of this size. but usually move less than 400 m (1,300 ft) in a day. The growing tips of Cephalostachyum ef uiguieri selected by the golden bamboo lemur (Hapalemuraureus) contained 15 mg of cyanide per 100 g fresh weight bamboo while the leaves of C. perrieri selected by the gentle bamboo lemur (H. griseus)and the mature culms of C. cf uiguieri selected by the greater bamboolemur (H. simus) did not contain cyanide. Cyanide loving lemurs who ingest enough cyanide each day to kill a similar sized animal a few times over. (1989).
