Brookesia
''Brookesia'' is a genus of chameleons, endemic to Madagascar, that range from small to very small in size, and are known collectively as leaf chameleons (though this name also commonly is used for species in the genera ''Rieppeleon'' and ''Rhampholeon''). ''Brookesia'' includes species considered to be the world's smallest chameleons, and are also among the smallest reptiles. Members of the genus ''Brookesia'' are largely brown and most are essentially terrestrial. A significant percentage of the species in the genus were only identified to science within the last three decades, and a number of species that still have not received a scientific name are known to exist. Most inhabit very small ranges in areas that are difficult to access, and due to their small size and secretive nature, they have been relatively poorly studied compared to their larger relatives. ''Brookesia'' are abundant in low-disturbance riparian zones and low-disturbance rainforests. ''Brookesia'' are scar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brookesia Bekolosy
''Brookesia bekolosy'' also known as the Bekolosy leaf chameleon is a species of chameleon that is endemic to Madagascar. It was described by Raxworthy and Nussbaum in 1995. The International Union for Conservation of Nature classed the species as Endangered, and in 1992 the single specimen of it was recorded. Description and habitat ''Brookesia bekolosy'' has only been collected once, being a single specimen from Bekolosy in the Manongarivo Special Reserve (Manongarivo Reserve) in the region of Diana in 1992. The species is believed to only be found at the Bekolosy Plateau, although further information is unknown. Its habitat is posited as between above mean sea level. Despite lack of specifics as to its extent, the International Union for Conservation of Nature classed ''B. bekolosy'' as an endangered species because it is not likely to cover more than , and it is found in an area where logging is becoming common.

Brookesia Betschi
''Brookesia betschi'', commonly known as Blanc's leaf chameleon or the Marojejy leaf chameleon, is a species of lizard in the family Chamaeleonidae. The species is endemic to Madagascar. Taxonomy ''B. betschi'' was originally described by Édouard-Raoul Brygoo, Charles Pierre Blanc and Charles Antoine Domergue in 1974. The type specimen was collected in 1973, at in a forest in Marojejy. Etymology The specific epithet, ''betschi'', honours French biologist Jean-Marie Betsch. Geographic range and habitat ''B. betschi'' is found in forests of northern Madagascar at altitudes of . It is found in subhumid forests in the Manongarivo Reserve, the Anjanaharibe-Sud Reserve, Marojejy National Park and the Tsaratanana Reserve, as well as in forests between them, over a total area of . Conservation status The International Union for Conservation of Nature has rated the Marojejy leaf chameleon as Near Threatened due to the loss of rainforest in northern Madagascar.

Brookesia Superciliaris
The brown leaf chameleon or stump-tailed chameleon (''Brookesia superciliaris'') is a small chameleon found along the eastern coast of Madagascar, as well as the island of Nosy Boraha. Its appearance mimics that of a dead leaf. The taxonomy is in need of revision. Description The brown leaf chameleon is distinguished by its elongated, high, laterally squashed body that resembles a rolled-up, dead leaf. The size and appearance of this chameleon varies considerably over its vast range, and it may be any shade of brown, beige, grey, olive, green, or dark red, but usually display colours and patterns that mimic a dead leaf. Despite its tiny size, the brown leaf chameleon has an imposing appearance due to two pronounced horns that protrude from the head above each eye and four spiny scales that jut from the throat.Nečas, P. and Schmidt, W.

Smallest Organisms
The smallest organisms found on Earth can be determined according to various aspects of organism size, including volume, mass, height, length, or genome size. Given the incomplete nature of scientific knowledge, it is possible that the smallest organism is undiscovered. Furthermore, there is some debate over the definition of life, and what entities qualify as organisms; consequently the smallest known organism (microorganism) is debatable. Microorganisms Obligate endosymbiotic bacteria The genome of '' Nasuia deltocephalinicola'', a symbiont of the European pest leafhopper, '' Macrosteles quadripunctulatus'', consists of a circular chromosome of 112,031 base pairs. The genome of ''Nanoarchaeum equitans'' is 490,885 nucleotides long. ''Pelagibacter ubique'' ''Pelagibacter ubique'' is one of the smallest known free-living bacteria, with a length of and an average cell diameter of .

Chameleon
Chameleons or chamaeleons (family Chamaeleonidae) are a distinctive and highly specialized clade of Old World lizards with 202 species described as of June 2015. The members of this family are best known for their distinct range of colors, being capable of shifting to different hues and degrees of brightness. The large number of species in the family exhibit considerable variability in their capacity to change color. For some, it is more of a shift of brightness (shades of brown); for others, a plethora of color-combinations (reds, yellows, greens, blues) can be seen. Chameleons are distinguished by their zygodactylous feet, their prehensile tail, their laterally compressed bodies, their head casques, their projectile tongues, their swaying gait, and crests or horns on their brow and snout. Chameleons' eyes are independently mobile, and because of this there are two separate, individual images that the brain is analyzing of the chameleon’s environment. When hunting prey, they ...

Brookesia Nana
''Brookesia nana'', also known as the nano-chameleon, is a species of chameleon endemic to montane rainforests in northern Madagascar. Described in 2021, it could represent the world's smallest reptile. Unlike some chameleons, ''Brookesia nana'' does not change colors. The species was discovered by herpetologist Frank Glaw and other German researchers in 2021 in the rainforest on the Sorata massif in northern Madagascar. ''Brookesia nana'' is not arboreal, as it tends to inhabit the forest floor. It is likely that the species is endangered due to deforestation in Madagascar. Miniaturism is believed to evolve from habitat loss. Description The nano-chameleon is blotchy brown in color. Adult males measure 22 mm (0.87 inch) in total length (including tail), while females are slightly larger at 29 mm (1.1 inches). Like other ''Brookesia ''Brookesia'' is a genus of chameleons, endemic to Madagascar, that range from small to very small in size, and are known collectively as le ...

Joshua Brookes
Joshua Brookes (24 November 1761 – 10 January 1833) was a British anatomist and naturalist. Early life Brookes studied under William Hunter, William Hewson, Andrew Marshall, and John Sheldon, in London. He then attended the practice of Antoine Portal and other eminent surgeons at the Hôtel-Dieu de Paris. Brookesian Museum Brookes became a teacher of anatomy in London, and the founder of the Brookesian Museum of Comparative Anatomy. This private museum is described in the 1830 catalogue ''Museum Brookesianum''. Later life Elected a Fellow of the Royal Society in 1819, Brookes gave up teaching in 1826, in bad health. After vainly endeavouring to dispose of his museum collection entire, he sold it off piecemeal. The final sale took place on 1 March 1830, and on 22 following days. He died on 10 January 1833 in Great Portland Street, London. Works Brookes was the first to place the Cheetah in its own genus, which he established in 1828 as ''Acinonyx''. His published wri ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...
