Brookesia Tuberculata
The Mount d'Ambre leaf chameleon (''Brookesia tuberculata'') is a diminutive chameleon from far northern Madagascar. Similar species A 1999 paper in the ''Journal of Zoology'' disputed a 1995 paper which considered this species and '' B. peyrierasi'' to be the same species as '' B. minima''. The later paper discussed the same details as the first – subtle morphological differences in the hemipenises of the respective species and determined they were not conspecific. They also found differences in the arrangement of head crests and in minute spines above the eyes. Bibliography *Klaver, C. & W. Boehme. 1997. ''Chamaeleonidae. Das Tierreich'', 112: i-xiv' 1 - 85.

François Mocquard
François Mocquard (27 October 1834 – 19 March 1917) was a French herpetologist born in Leffond, Haute-Saône. In 1860 he was named ''préparateur du physique'' after receiving his Bachelor of Science degree at the Faculty of Besançon. Subsequently, he earned degrees in physical sciences (1862), mathematical sciences (1865) and medicine (1873). Despite being middle-aged, he made a career change, and began studying natural sciences in the laboratory of Alphonse Milne-Edwards (1835-1900) at the Muséum national d'histoire naturelle in Paris. In 1884 he earned his doctorate of sciences with a thesis on the structure of the stomach in crustaceans, afterwards working as an assistant in the ichthyology and herpetology department at the museum. During his career he described numerous herpetological taxa, most notably species from Madagascar, Tonkin, Borneo, Mexico and Central America. In addition, he has several species named after him, including reptiles, '' Alluaudina mocquardi'', ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

Brookesia Peyrierasi
''Brookesia peyrierasi'' is a species of diminutive chameleon, a lizard in the family Chamaeleonidae. The species is endemic to north-eastern Madagascar. It is known commonly as Peyrieras's pygmy chameleon, named after the herpetologist André Peyriéras. Similar species A 1999 paper in the '' Journal of Zoology'' disputed a 1995 paper which considered this species and '' B. tuberculata'' to be the same species as '' B. minima''.

Brookesia Minima
''Brookesia minima'', (common names of which include the dwarf chameleon, the Madagascan dwarf chameleon, the minute leaf chameleon, and the Nosy Be pygmy leaf chameleon), is a diminutive chameleon that was regarded as the smallest lizard of the Chamaeleonidae until a smaller species, ''Brookesia nana'', was described in 2021. Range ''B. minima'' is endemic to Nosy Be, an island located just off the northwest coast of Madagascar, but has extralimital distribution to Manongarivo Reserve on Madagascar's northwest coast. Description ''B. minima'' is the third-smallest lizard ever described. The species has the independently rotating eyes and prehensile tail characteristic of all chameleons. It is coloured light grey on the head, back and tail, although the tail becomes orange then yellowish towards the tip. The sides of the body are brown, occasionally interrupted by dark brown spots, and the limbs are almost entirely dark brown. Spotted patterning appears to be a stress coloura ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Hemipenis
A hemipenis (plural hemipenes) is one of a pair of intromittent organs of male squamates (snakes, lizards and worm lizards). Hemipenes are usually held inverted within the body, and are everted for reproduction via erectile tissue, much like that in the human penis. They come in a variety of shapes, depending on species, with ornamentation, such as spines or hooks. The female homologue is the hemiclitoris. Background The hemipenis is the intromittent organ of squamata, which is the second largest order of vertebrates with over 9000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate. Squamate hemipenes also develop from a different cell origin, originating from the same embryonic cells that produce the limbs, whereas mammalian penises arise from the embryonic cells that develop the tail.

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] |
Endemic Fauna Of Madagascar
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Of Madagascar
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated ...
