This wonderful little primate is typically about 11-18″ long (not including the 9-13″ long tail) and weighs only 3.5 lbs on average. 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. ... Ranomafana came to world attention in 1986 when the golden bamboo lemur was discovered. is most active at dawn and dusk. 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. 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. The young are highly dependent on their mothers and are kept hidden in dense vegetation for the first two weeks. Cyanide loving lemurs who ingest enough cyanide each day to kill a similar sized animal a few times over. Lemurs are a special type of primate called prosimians, which are the oldest group of primates. The golden bamboo lemur (Hapalemur aureus), bokombolomena in Malagasy, is a medium-sized bamboo lemur endemic to south-eastern Madagascar. Unfortunately, the mechanism H. aureus uses to detoxify this poison is as yet unknown. Bamboo lemurs are a genus of 5 species, and are the only primates in the world that specialise on a bamboo diet. [4], The species is endemic to the rain forests of south–eastern Madagascar at elevations of 600–1,400 m (2,000–4,600 ft). Since each individual golden bamboo lemur … It was first described by Western science 30 years ago, in 1987. It is about the size of a domestic cat and is 28–45 cm (11–18 in) long plus a tail of 24–40 cm (9.4–15.7 in), and on average weighs 1.6 kg (3.5 lb). 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. The park was opened in 1991 to protect this endangered lemur, as well as several other lemur species and its flora and fauna. Unique to Madagascar, these animals are thought to resemble the primitive ancestor of today's monkeys and apes. The growing shoots of this bamboo contain 0.015% of cyanide. These three sympatric species inhabit the same habitat and feed on the same bamboo species, Cephalostachyum cf viguieri and C. perrieri. 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 park was created in 1991. Their little cousin, the Grey Bamboo Lemur ( Hapalemur griseus ) eats less cyanide-producing bamboo, and their close relatives the Ringtailed Lemur ( Lemur catta ), Blue-eyed Black Lemur ( Eulemur flavifrons ), and Black and White Ruffed Lemur … It is known from the vicinity of Ranomafana National Park (first discovery in 1986 by Patricia Wright), Andringitra National Park (discovered in 1993), possibly in a forest corridor that connects Ranomafana with Andringitra National Park. The golden bamboo lemur is so called because of the golden fur around its face, inner limbs and belly. The growing shoots of this bamboo contain 0.015% of cyanide. of tropical forest. Ironically, the most protein-rich part of bamboo is also the most deadly; giant bamboo shoots contain high amounts of cyanide. Hapalemur aureus Discovered in 1987, critically endangered due to its very specialised diet of Volohosy bamboo leaves, a tree endemic to Madagascar. The growing shoots of this bamboo contain 0.015% (1 part in 6667) of cyanide. It is about the size of a domestic cat and is 28–45 cm (11–18 in) long plus a tail of 24–40 cm (9.4–15.7 in), and on average weighs 1.6 kg (3.5 lb). [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). [5] The growing shoots of this bamboo contain 0.015% (1 part in 6667) of cyanide. As its name indicates, this lemur feeds almost exclusively on grasses, especially the giant bamboo or volohosy (Cathariostachys madagascariensis) feeding on new shoots, leaf bases and the creepers. The golden bamboo lemur is crepuscular i.e. The growing shoots of this bamboo contain 0.015% (1 part in 6667) of cyanide. 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. H. aureus meanwhile eats only the shoots of C. cf. The amount of cyanide consumed daily by this species is enough to kill three men. 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. Studies suggest that golden bamboo lemurs’ gastrointestinal tract and kidneys absorb the cyanide, as it has tested positive in … The growing tips of Cephalostachyum ef uiguieri selected by the golden bamboo lemur (Hapalemuraureus) contained 15 mg of cyanide per 100 g fresh … International Union for Conservation of Nature, "Images and movies of the golden bamboo lemur", "Photos of Golden bamboo lemurs - photos for conservation, science, education and you", https://en.wikipedia.org/w/index.php?title=Golden_bamboo_lemur&oldid=968218396, IUCN Red List critically endangered species, Creative Commons Attribution-ShareAlike License, This page was last edited on 18 July 2020, at 00:08. H. simus prefers the woody pulp and culms of C. cf. 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. There are over 35 species of lemur living in Madagascar, inhabitaing a variety of natural habitats, from rainforest to desert like plains. viguieri, while H. griseus eats the leaf bases of both species and selects the shoots of C. perrieri. These are weaned after about four months (if the food supply is ample) and are fully mature at two years of age. It is 28–45 cm long plus a tail of 24–40 cm, and weighs on average 1.6 kg. However, large amounts of cyanide have been measured in the feces which are the food source specifically selected by a species of dung beetle who seems to have co-evolved with the Golden bamboo Lemur. More than 90% of the diets of the Greater Bamboo Lemur (Prolemur simus) and Golden Bamboo Lemur (Hapalemur aureus) are cyanide-producing bamboo. The golden bamboo lemur (Hapalemur aureus, Malagasy bokombolomena) is a medium-sized bamboo lemur endemic to south-eastern Madagascar. Every day the golden bamboo lemur eats around 500g of soft stalks and growing tips of giant bamboo, which represents 12 times the lethal dose of cyanide for … There are three species of Bamboo lemurs: the Greater Bamboo Lemur (H. simus), three subspecies of the Lesser or Gentle Bamboo Lemur, (H. griseus), and the Golden Bamboo Lemur, (H. aureus), who has the dubious honor of being the world's most recently discovered primate, having been found by Dr. Patricia Wright of SUNY Stonybrook in 1984. The golden bamboo lemur is known for feeding primarily on the new shoots of the giant bamboo plant, which contains 12x the lethal dose of cyanide ☠️ per pound (what the golden bamboo lemur eats in a day). The golden bamboo lemur is crepuscular i.e. A cyanide is a chemical compound that contains the group C≡N. It turns out that each species eats a different part of the bamboo. 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. Some manifestations of toxicity are subtle. The golden bamboo lemur is crepuscular. [1][4], The golden bamboo lemur was discovered in 1986 by Dr. Patricia Wright, in what is now Ranomafana National Park. Lemurs that go out to hunt only … Big thanks to Raheriniaina Celestin for filming while our Communications Director, Sara, snapped some still images! Gestation lasts 135 to 150 days and ends between September and January, when the female bears one to two young. 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. However, large amounts of cyanide have been measured in the feces which are the food source specifically selected … On the other hand, the Golden Bamboo Lemur eats an average of 500 g of this cyanide laden bamboo every day, thus intaking an estimated 12 times the toxic dose for a primate of its body mass. New!! It is 28–45 cm long plus a tail of 24–40 cm, and weighs on average 1.6 kg. 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. As its name indicates, this lemur feeds almost exclusively on grasses, especially the giant bamboo or Cathariostachys madagascariensis. Unfortunately, the mechanism H. aureus uses to detoxify this poison is as yet unknown. 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. This species has been transformed and developed to resist high levels of cyanide, which eat in small amounts of bamboo leaves. Glander, K. E., Wright, P. C., Seigler, D. S., Randrianasolo, V., & Randrianasolo, B. The HCNp ranged from 209±72 μmol cyanide*g⁻¹ dwt in Cathariostachys madagascariensis to no cyanide in Bambusa madagascariensis. The growing shoots of this bamboo contain 0.015% (1 part in 6667) of cyanide. viguieri. 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. With an adult weight of approximately 1.3–1.7 kg, it is the largest member of the genus Hapalemur, since the greater bamboo lemur (formerly H. simus) has now been placed in its own genus, Prolemur (see Groves, 2001). is a most active at dawn and dusk. Find out more in my blog post. Description The golden bamboo lemur is crepuscular i.e. 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. but usually move less than 400 m (1,300 ft) in a day.

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. The question then arises, what prevents the H. griseus from encroaching on the territory of their cousins by eating the shoots of both bamboo species? The golden bamboo lemur (Hapalemur aureus), bokombolomena or varibolomena in Malagasy, is a medium-sized bamboo lemur endemic to south-eastern Madagascar. [1], As its name indicates, this lemur feeds almost exclusively on grasses, especially the giant bamboo or volohosy (Cathariostachys madagascariensis) feeding on new shoots, leaf bases and the creepers. 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. Golden bamboo lemur (Hapalemur aureus) male eating a poisonous (but not to him), cyanide-containing bamboo shoot in rainforest. viguieri contain 15 mg of cyanide per 100 g of fresh weight. Females have a gestation period of approximately 138 days and give birth to one infant (occasionally two) at the beginning of the rainy season, in November or December. 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 shoots of C. cf. km. How bamboo lemurs can detoxify the high amounts of cyanide (from bamboo shoots) in their diets is unknown. 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 H. griseus stay away from the shoots of this plant because they are highly toxic.

See more » Cyanide. The population is declining, predominantly due to hunting and to ongoing habitat loss; with only about 1,000 individuals remaining. 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. The Golden Bamboo Lemur (Hapalemur aureus) is a medium-sized bamboo lemur endemic to south-eastern Madagascar. Among these are the genus Hapalemur or the Bamboo lemurs. The species is classified as critically endangered by the International Union for Conservation of Nature (IUCN) and is listed on Appendix I of CITES, CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention).[1][5][2]. PLEASE NOTE:"Poisonous" does not mean deadly. The golden bamboo lemur was first discovered in 1985, and was described two years later (Meier et al., 1987).
