Afrolychas Burdoi
''Afrolychas'' is a genus of scorpion in the family Buthidae. There are two species in this genus, both of which used to belong to the genus ''Lychas''. The genus was described in 2019 by František Kovařík. The genus name ''Afrolychas'' is a reference to the African range of its species and the fact that the two species used to be members of the genus ''Lychas''. ''Afrolychass closest relatives are believed to be the scorpions in the genus '' Pseudolychas''. '' Afrolychas braueri'' is one of the rarest scorpions in the world, as it is listed as critically endangered on the IUCN Red List.

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arachnid
Arachnida () is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons. Almost all adult arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word (''aráchnē'', 'spider'), from the myth of the hubristic human weaver Arachne, who was turned into a spider. Almost all extant arachnids are terrestrial, living mainly on land. However, some inhabit freshwater environments and, with the exception of the pelagic zone, marine environments as well. They comprise over 100,000 named species, of which 47,000 are species of spiders. Morphology Almost all adult arachnids have eight legs, unlike adult inse ...

Scorpion
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs, and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The venomous sting is used for offense and defense. During courtship, the male and female grasp each other's pincers and dance while he tries to move her onto his s ...

Buthidae
The Buthidae are the largest family of scorpions, containing about 100 genera and 1339 species as of 2022. A few very large genera (''Ananteris'', ''Centruroides'', '' Compsobuthus'', or '' Tityus'') are known, but a high number of species-poor or monotypic ones also exist. New taxa are being described at a rate of several new species per year. They have a osmopolitandistribution throughout tropical and subtropical environments worldwide. Together with four other families, the Buthidae make up the superfamily Buthoidea. The family was established by Carl Ludwig Koch in 1837. Around 20 species of medically important (meaning potentially lethal to humans) scorpions are known, and all but one of these ('' Hemiscorpius lepturus'') are members of the Buthidae. In dead specimens, the spine beneath the stinger, characteristic for this family, can be observed.

Lychas
''Lychas'' is a genus of scorpions belonging to the family Buthidae. It is one of the most widespread genus of the scorpions, where the species are found throughout in Africa and Seychelles, and in the Oriental region from India to Melanesia. Description Total length is 21.8 to 90 mm. Sternum type 1 is subpentagonal or subtriangular. Pedipalps are orthobothriotaxic. Cheliceral fixed finger with a single ventral denticle. Third and fourth legs consists with tibial spurs. Pectines have conspicuous or inconspicuous fulcra, but rarely can be without fulcra. There are about 8 to 26 pectinal teeth. Movable fingers of pedipalps consist with six rows of granules. Total number of terminal granules is 6 or 7. Carapace with horizontal entire dorsal surface laterally. Telson with a distinct subaculear tooth.

Afrolychas Braueri
''Afrolychas braueri'', commonly known as the Seychelles forest scorpion, is a species of scorpion in the family Buthidae. It is currently thought to survive only on Silhouette Island, Seychelles, although the species was historically found on two additional Seychellois islands. This scorpion lives in leaf litter in forests that are largely unaffected by invasive plant species. It is a small yellowish-brown scorpion with three prominent keels on the dorsal surface of its mesosoma, which distinguishes it from other scorpions. While not much is known about the Seychelles forest scorpion's ecology due to the paucity of sightings, it is known to rely solely on its venom to capture its prey and defend its young. Its venom is not dangerous to humans. The Seychelles forest scorpion has only been observed a handful of times and as such is believed to live in very low population densities. It is listed as a critically endangered species by the International Union for Conservation of Nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Karl Kraepelin
Karl Matthias Friedrich Magnus Kraepelin (; ; 14 December 1848 – 28 June 1915) was a German naturalist who specialised in the study of scorpions, centipedes, spiders and solfugids, and was noted for his monograph ''Scorpiones und Pedipalpi'' (Berlin) in 1899, which was an exhaustive survey of the taxonomy of the Order Scorpiones. From 1889 to 1914, he served as the Director of the ', which was destroyed during World War II, and worked on myriapods from 1901 to 1916. Biography Karl Kraepelin was born in Neustrelitz. He studied natural sciences in Göttingen and Leipzig, where he earned his PhD in 1873, and taught as a teacher of mathematics and sciences in schools in Leipzig and Hamburg from 1873 to 1889. In 1884 he became a member of the German Academy of Sciences Leopoldina. He was a member of the Assembly of University Professors of Hamburg from 1901 and the Faculty Council of Colonial Institute from 1908.
