Brookesia is a genus of chameleons, lizards in the family Chamaeleonidae. The genus is endemic to Madagascar. Member species range from small to very small in size, and are known collectively as leaf chameleons. 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.
The smallest organisms found on Earth can be determined according to various aspects of organism size, including volume, mass, height, length, or genome size.
Montagne d'Ambre National Park is a national park in the Diana Region of northern Madagascar. The park is known for its endemic flora and fauna, water falls and crater lakes. It is 1,000 km (620 mi) north of the capital, Antananarivo, and is one of the most biologically diverse places in all of Madagascar with seventy-five species of birds, twenty-five species of mammals, and fifty-nine species of reptiles known to inhabit the park.
The composition of Madagascar's wildlife reflects the fact that the island has been isolated for about 88 million years. The prehistoric breakup of the supercontinent Gondwana separated the Madagascar-Antarctica-India landmass from the Africa-South America landmass around 135 million years ago. Madagascar later split from India about 88 million years ago, allowing plants and animals on the island to evolve in relative isolation.
The Antsingy leaf chameleon is a species of lizards in the family Chamaeleonidae. The species is also referred to as Armoured leaf chameleon.
Brookesia minima,, is a diminutive chameleon that was regarded as the smallest lizard of the Chamaeleonidae until a smaller species, Brookesia nana, was described in 2021.
Brookesia ebenaui is a chameleon, a lizard in the family Chamaeleonidae. The species, which is endemic to Madagascar, can rapidly change color among various earth hues.
The brown leaf chameleon or stump-tailed chameleon 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.
Brookesia micra, also known as the Nosy Hara leaf chameleon is a species of chameleons from the islet of Nosy Hara in Antsiranana, Madagascar. At the time of its discovery, it was the smallest known chameleon and among the smallest reptiles, until the 2021 discovery of the even smaller B. nana. Adult B. micra can grow up to 29 mm (1.1 in) in length.
Brookesia stumpffi, also known as the plated leaf chameleon, is a species of chameleon found in some parts of Madagascar. It can be found in Nosy Bé, north-west Madagascar, Nosy Komba, and Nosy Sakatia.
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.
The naturelle leaf chameleon is a species of chameleon, a lizard in the family Chamaeleonidae. The species is endemic to Madagascar. It was rated as an endangered species by the International Union for Conservation of Nature on its Red List of Threatened Species. The species was described by Édouard-Raoul Brygoo, Charles Pierre Blanc, and Charles Antoine Domergue in 1970.
Brookesia bonsi is a species of chameleons, a lizard in the family Chamaeleonidae. The species is endemic to Madagascar, and was initially described by Guy A. Ramanantsoa in 1980. The International Union for Conservation of Nature ranked this species as Critically Endangered.
Brookesia confidens, also known as the leaf chameleon, is one of the world's smallest species of chameleons. It is endemic to the Ankarana Nature Reserve in Madagascar. It was first described in 2012 by F. Glaw, J. Koehler, T.M. Townsend and M. Vences.
Brookesia exarmata, also known as the dwarf chameleon, is a species of chameleon endemic to Madagascar. It was first described by Schimmenti and Jesu in 1996, and the International Union for Conservation of Nature (IUCN) has classed it as an endangered species of animal.
Brookesia thieli, commonly also known as Domergue's leaf chameleon or Thiel's pygmy chameleon, is a species of lizard in the family Chamaeleonidae. The species is endemic to eastern Madagascar, with a type locality of Ambodimanga, Andapa. It was first described in 1969 by Édouard-Raoul Brygoo and Charles Antoine Domergue, and it was ranked by the International Union for Conservation of Nature as "least concern". B. thieli is thought to be found over an area of 43,865 km2 (16,936 sq mi) at 875–1,200 m (2,871–3,937 ft) above sea level.
Brookesia valerieae is a species of chameleon, a lizard in the family Chamaeleonidae. The species is endemic to Madagascar. It was first described by Raxworthy in 1991. The IUCN have classed this species as endangered, and it is affected by slash-and-burn agriculture. It is not a protected species.
Calumma nasutum, the Madagascar pimple-nose chameleon, is a small species of chameleon found in Madagascar. The taxonomic identity of the species is currently uncertain and in need of revision, and this revision is likely to result in several newly described species. Several different data sets indicate that C. nasutum is a complex of several species.
Nosy Hara or Nosy Hara National Park is an uninhabited limestone islet in the Diana Region off the northwest coast of Madagascar. It is the habitat of Brookesia micra, the smallest known chameleon. Since 2007, Nosy Hara has been part of a Marine Protected Area.
Brookesia desperata is a species of chameleons. It is endemic to Foret d'Ambre Special Reserve in north Madagascar, and is a critically endangered species due to the decline of its habitat. This decline is attributed to clearance of forest for crops, charcoal production, timber extraction, small-scale quarrying and cattle grazing. It was named desperata to provoke thought regarding the desperately threatened habitat of Madagascar's micro-endemic species. They can be found roosting above ground on small branches or leaves 5–100 cm above ground at night. B. desperata was described in 2012 by a research team led by Dr. Frank Glaw from the Zoologische Staatssammlung München.
