Mainland Drill
The mainland drill (''Mandrillus leucophaeus leucophaeus'') is a subspecies of the endangered drill A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driverchuck. Hand-operated types are dramatically decreasing in popularity and cordless battery-powered ones proliferating due to .... It is distinguished by ringed yellow and black coloring on its crown, and is otherwise similar to the Bioko drill.

Frédéric Cuvier
Georges-Frédéric Cuvier (28 June 1773 – 24 July 1838) was a French zoologist and paleontologist. He was the younger brother of noted naturalist and zoologist Georges Cuvier. Career Frederic was the head keeper of the menagerie at the Muséum d'Histoire Naturelle in Paris from 1804 to 1838. He named the red panda (''Ailurus fulgens'') in 1825. The chair of comparative physiology was created for him at the Muséum d'Histoire Naturelle in 1837. He was elected as a foreign member of the Royal Society in 1835. He is mentioned in Charles Darwin's ''On the Origin of Species'' (Chapter VII) as having worked on animal behaviour and instinct, especially the distinction between habit and instinct. He is also mentioned in Herman Melville's ''Moby-Dick'' (Chapter 32) as having written on the topic of whales. Evolution Cuvier has been described as the first scientist to use terms ''"héréditaire"'' (hereditary) in 1807 and "heredity” in 1812 in their now biological context. He used b ...

Drill (mammal)
The drill (''Mandrillus leucophaeus'') is a primate of the family Cercopithecidae (Old World monkeys), related to baboons and even more closely to mandrills. Description The drill is a short-tailed monkey up to long, similar in appearance to the mandrill, but lacks the bright blue and red on the face of that species. It has high sexual dimorphism in weight, with males weighing up to and females up to .ARKive Drill (''Mandrillus leucophaeus'') The body is overall a dark grey-brown. Mature males have a pink lower lip and white chin on a dark grey to black face with raised grooves on the nose. The rump is pink, mauve and blue. Female drills lack the pink chin. Taxonomy Two subspecies of drill are accepted by some authorities, but are not considered distinct by others:Primate Info NetDrill/ref> * Mainland drill, ''Mandrillus leucophaeus leucophaeus'' * Bioko drill, ''Mandrillus leucophaeus poensis'' Their closest relative is the mandrill (''Mandrillus sphinx''), found from s ...

Bioko Drill
The Bioko drill (''Mandrillus leucophaeus poensis'') is a subspecies of the drill, an Old World monkey. It is endemic to Bioko Island, Equatorial Guinea, located off the west coast of Africa. The drill is one of the largest monkey species, and is considered endangered. The Bioko drill was separated from their mainland counterpart, due to rising sea levels after the end of the last ice age, around 10,000 years ago. The capital of Equatorial Guinea, Malabo, is on Bioko Island. The Malabo market is the primary point of sale for bushmeat on Bioko Island. The drill plays an important role in the cultural tradition of bushmeat consumption, and is locally considered to be tasty, and in some regions, a delicacy. The commercialisation of hunting on Bioko Island has made this practice unsustainable. Hunting of the Bioko drill is banned in most areas of Bioko Island, as they predominantly inhabit protected areas on the island. However, the ban is considered ineffective; hunting remains th ...

Mandrillus
''Mandrillus'' is a genus of large Old World monkeys distributed throughout central and southern Africa, consisting of two species: ''M. sphinx'' and ''M. leucophaeus'', the mandrill and drill, respectively. ''Mandrillus'', originally placed under the genus ''Papio'' as a type of baboon, is closely related to the genus ''Cercocebus''. They are characterised by their large builds, elongated snouts with furrows on each side, and stub tails. Both species occupy the west central region of Africa and live primarily on the ground. They are frugivores, consuming both meat and plants, with a preference for plants. ''M. sphinx'' is classified as vulnerable and ''M. leucophaeus'' as endangered on the ''IUCN Red List of Threatened Species''. Taxonomy ''Mandrillus'' is a genus within the tribe Papionini, which in turn is under the subfamily Cercopithecinae. This subfamily is classified under the family of Old World monkeys (Cercopithecidae) within the infraorder Simiiformes. The Papionini ...

Primates Of Africa
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large brai ...

Endangered Animals
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
