Stromatopelma
''Stromatopelma'' is a genus of African tarantulas that was first described by Ferdinand Anton Franz Karsch in 1881. They are renowned for their potent venom that uses stromatoxin peptides to induce medically significant effects. Species it contains five species and one subspecies, found in Africa: *'' Stromatopelma batesi'' ( Pocock, 1902) – Cameroon, Congo *'' Stromatopelma calceatum'' (Fabricius, 1793) (type) – West Africa **'' Stromatopelma c. griseipes'' (Pocock, 1897) – West Africa *'' Stromatopelma fumigatum'' (Pocock, 1900) – Equatorial Guinea (Mbini) *'' Stromatopelma pachypoda'' (Strand, 1908) – Cameroon *'' Stromatopelma satanas'' (Berland, 1917) – Gabon, Congo In synonymy: *''Stromatopelma alicapillatum'' Karsch, 1881 = '' Stromatopelma calceatum'' *''Stromatopelma aussereri'' (Becker, 1879) = '' Stromatopelma calceatum'' *''Stromatopelma brachypoda'' (Pocock, 1897) = '' Stromatopelma calceatum'' *''Stromatopelma horrida'' (Thorell, 1899) = '' Stromato ...

Stromatopelma Fumigatum
''Stromatopelma fumigatum'' is a species of spider in the tarantula family, Theraphosidae, endemic to Río Muni. Diagnosis ''Stromatopelma fumigatum'' is characterized by the labio-sternal mound (i.e. small "bumps") arrangement: six mounds on the edge of the sternum, the anterior one being largest, and the median being the smallest. Even though the anterior mound is still the largest, it is smaller than in other species. Behavior ''Stromatopelma fumigatum'', like all stromatopelmine gerena, are famously aggressive, therefore are rarely kept as pets. They are arboreal, living in palm trees mainly, which provide shade from the sun in the flat plains of west Africa, and are highly territorial, showing a high amount of cannibalism Cannibalism is the act of consuming another individual of the same species as food. Cannibalism is a common ecological interaction in the animal kingdom and has been recorded in more than 1,500 species. Human cannibalism is also well document .... R ...

Stromatopelma Calceatum
''Stromatopelma calceatum'' also known as the featherleg baboon tarantula, was first described by Johan Christian Fabricius in 1793. It is found in West Africa and has gone through a variety of scientific names during its existence. Description Females live up to 15 years, while males only live to 4 years. The carapace is a tan creamy color, with some black striping, the opisthosoma is a tan creamy color with a black fishbone pattern. The legs are the same color covered in orangish hairs. Behavior They are an arboreal old world tarantula, creating a tube-like web, in the lower forest regions. They are quite a defensive tarantula, and will usually stay inside their webs until night. Though adults are arboreal, younger specimens have been observed burrowing An eastern chipmunk at the entrance of its burrow A burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of locomotion. ...

Theraphosidae Genera
Tarantulas comprise a group of large and often hairy spiders of the Family (biology), family Theraphosidae. , 1,100 species have been identified, with 166 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes. Overview Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.Pomeroy, R. (2014, February 4). Pub.

Stromatoxin
Stromatoxin is a spider toxin that blocks certain delayed-rectifier and A-type voltage-gated potassium channels. Etymology Stromatoxin was first identified in the venom of the African tarantula '' Stromatopelma calceatum'' (the featherleg baboon spider), from which it derives its name. The technical abbreviation for the toxin is ScTx1. Chemistry Stromatoxin is a peptide consisting of 34 amino acids that belongs to the structural family of ‘ inhibitor cystine knot’ spider peptides. The toxin was identified using a systematical screening of the effects of toxins of several species of tarantulas on Kv2-channels of '' Xenopus laevis'' (the African clawed frog) . Bioassay guided fractionation and chromatography identified stromatoxin as the functional component. The full sequence of the venom was obtained in a single run of Edman sequencing and confirmed by mass spectrometry. The sequence of this toxin is ‘dctrmfgacr rdsdccphlg ckptskycaw dgti’, for an explanation of these s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand Karsch
Ferdinand Anton Franz Karsch (2 September 1853, in Münster – 20 December 1936, in Berlin) was a German arachnologist, entomologist and anthropologist. He also wrote on human and animal sexual diversity with his mother's maiden name included as Ferdinand Karsch-Haack from around 1905. Life and work The son of doctor Anton Karsch, he was educated at the Friedrich Wilhelm University in Berlin and published a thesis on the gall wasp in 1877. From 1878 to 1921 he held the post of curator at the Museum für Naturkunde Berlin. Between 1873 and 1893, he published a catalogue of the spiders of Westphalia; he also published numerous articles on the specimens that the museum received from various explorers and naturalists working in Africa, in China, in Japan, in Australia, etc. This publication of others' work sometimes led to disputes over priority and nomenclature, for example with Pickard-Cambridge. Alongside his zoological activities, he published many works on sexuality an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gabon
Gabon ( ; ), officially the Gabonese Republic (), is a country on the Atlantic coast of Central Africa, on the equator, bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo to the east and south, and the Gulf of Guinea to the west. It has an area of and a population of million people. There are coastal plains, mountains (the Crystal Mountains (Africa), Cristal Mountains and the Chaillu Massif in the centre), and a savanna in the east. Libreville is the country's capital and largest city. Gabon's original inhabitants were the African Pygmies, Bambenga. In the 14th century, Bantu expansion, Bantu migrants also began settling in the area. The Kingdom of Orungu was established around 1700. France colonised the region in the late 19th century. Since its independence from France in 1960, Gabon has had four President of Gabon, presidents. In the 1990s, it introduced a multi-party system and a democratic constitution that aimed for a more tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
