Mesoperipatus Tholloni
''Mesoperipatus'' is a monospecific genus of velvet worm in the Peripatidae family, containing a single species ''Mesoperipatus tholloni''. It is found in Gabon, making it the only known species of velvet worm in the tropics of Africa, and the only known species of peripatid velvet worm in Africa. Females of this species have 24 to 27 pairs of legs; males have 23 or 24. Conservation In terms of conservation status, this species is listed as Data Deficient on the IUCN Red List The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biol ....

Eugène Louis Bouvier
Eugène Louis Bouvier (9 April 1856, in Saint-Laurent-en-Grandvaux – 14 January 1944, in Paris) was a French entomologist and carcinologist. Bouvier was a professor at the Muséum national d'histoire naturelle. Biography Following graduation at the normal school in Lons-le-Saunier, he taught classes in Clairvaux, Versailles, Saint-Cloud and Villefranche-sur-Saône. From 1882 to 1887, he served as a "boursier" at the Muséum national d'histoire naturelle, where he studied with Alphonse Milne-Edwards (1835–1900) and Edmond Perrier (1844–1921). Together with Milne-Edwards, he worked on some of the crustaceans from the ''Travailleur'' and ''Talisman'' expeditions (1880–1883). In 1887, he earned his doctorate in natural sciences with a dissertation involving prosobranch gastropods, ''Système nerveux, morphologie générale et classification des Gastéropodes prosobranches''. In 1889 he became an associate professor at the ''Ecole supérieure de pharmacie de Paris'', and in 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onychophora
Onychophora (from grc, ονυχής, , "claws"; and , , "to carry"), commonly known as velvet worms (due to their velvety texture and somewhat wormlike appearance) or more ambiguously as peripatus (after the first described genus, '' Peripatus''), is a phylum of elongate, soft-bodied, many-legged panarthropods. In appearance they have variously been compared to worms with legs, caterpillars, and slugs. They prey upon other invertebrates, which they catch by ejecting an adhesive slime. Approximately 200 species of velvet worms have been described, although the true number of species is likely greater. The two extant families of velvet worms are Peripatidae and Peripatopsidae. They show a peculiar distribution, with the peripatids being predominantly equatorial and tropical, while the peripatopsids are all found south of the equator. It is the only phylum within Animalia that is wholly endemic to terrestrial environments, at least among extant members. Velvet worms are generally c ...

Peripatidae
Peripatidae is a family of velvet worms. The oldest putative representatives of the family herald from Burmese amber dated to the mid-Cretaceous, around 100 Ma, with representatives from Dominican and Baltic amber attesting to a broader distribution in the Palaeogene / Neogene; molecular variability suggests that the family's crown group may have arisen in the early Mesozoic. Description The Peripatidae exhibit a range of derivative features. They are longer, on average, than the Peripatopsidae and also have more leg pairs. The number of leg pairs in the Peripatidae range from 19 (in ''Typhloperipatus williamsoni'') to 43 (in ''Plicatoperipatus jamaicensis''). The gonopore is always between the penultimate leg pair. There are no oviparous species—the overwhelming majority are viviparous. The females of many viviparous species develop a placenta with which to provide the growing embryo with nutrients. Distribution The Peripatidae are restricted to the tropical and subtropical z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gabon
Gabon (; ; snq, Ngabu), officially the Gabonese Republic (french: République gabonaise), is a country on the west coast of Central Africa. Located on the equator, it is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of nearly and its population is estimated at million people. There are coastal plains, mountains (the Cristal Mountains and the Chaillu Massif in the centre), and a savanna in the east. Since its independence from France in 1960, the sovereign state of Gabon has had three presidents. In the 1990s, it introduced a multi-party system and a democratic constitution that aimed for a more transparent electoral process and reformed some governmental institutions. With petroleum and foreign private investment, it has the fourth highest HDI in the region (after Mauritius, Seychelles and South Africa) and the fifth highest GDP per capita (PPP) i ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Gabon
The wildlife of Gabon is composed of its flora and fauna. Gabon is a largely low-lying country with a warm, humid climate. Much of the country is still covered by tropical rainforest and there are also grasslands, savannas, large rivers and coastal lagoons. Overview Wildlife includes forest elephants, forest buffalos, various antelope and monkey species, sitatungas, leopards, three species of crocodiles, chimpanzees and gorillas, and several marine turtle species which nest along the coast. As of 2002, there were at least 190 species of mammals. Fauna Mammals Gabon has important populations of many mammals including about 35,000 gorillas, 50,000 forest elephants and 64,000 common chimpanzees. About a quarter of Africa's gorillas live in Gabon. Other large mammals include the hippopotamus, forest buffalo, bongo and red river hog. A variety of monkeys occur, including the endemic Sun-tailed monkey, and the near-endemic mandrill and white-collared managabey (here near-endemic me ...

Monotypic Protostome Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...
