Caerostris Darwini

picture info	Caerostris Darwini Darwin's bark spider (''Caerostris darwini'') is an orb-weaver spider that produces the largest known orb webs, ranging from , with bridge lines spanning up to . The spider was discovered in Madagascar in the Andasibe-Mantadia National Park in 2009. Its silk is the toughest biological material ever studied. Its tensile strength is 1.6 GPa. The species was named in honour of the naturalist Charles Darwin on November 24, 2009—precisely 150 years after the publication of '' The Origin of Species''. Description Darwin's bark spider (''Caerostris darwini'') is an orb-weaver spider – a member of the family Araneidae. Like other spiders of the genus, they display extreme sexual dimorphism, with large females and small males. Females vary in total body length from about , males being around one third or less of this length, at about . In a captive bred population, females were 14 (1.3–195) times heavier and 2.3 (1–4) times larger than males.Gregorič, M. et al. (2016)"Spi ...

picture info	Orb-weaver Spider Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs. The family has a cosmopolitan distribution, including many well-known large or brightly colored garden spiders. With 3,108 species in 186 genera worldwide, the Araneidae comprise the third-largest family of spiders (behind the Salticidae and Linyphiidae). Araneid webs are constructed in a stereotypical fashion, where a framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. Orb webs are also produced by members of other spider families. The long-jawed orb weavers (Tetragnathidae) were formerly included in the Araneidae; they are closely related, being part of the superfamily Arane ...

	Caerostris Extrusa ''Caerostris'', sometimes called bark spiders, is a genus of orb-weaver spiders first described by Tamerlan Thorell in 1868. Most species are found in south eastern Africa and neighboring Madagascar. Taxonomy The genus ''Caerostris'' was erected in 1868 by Tamerlan Thorell with the type species being ''Epeira mitralis'' Vinson, 1863, which Thorell transferred to ''Caerostris mitralis''. Up to 2009, only 11 species had been described. A further species, ''C. darwini'', was described in 2010, and six more species in 2015. Two of the "species", ''C. sexcuspidata'' and ''C. sumatrana'', will probably need to be divided further to produce genetically uniform species. A molecular phylogenetic study of 12 of the species of ''Caerostris'' produced the phylogenetic tree shown below, showing that the African and Madagascan species form a monophyletic group.

	Caerostris Sexcuspidata ''Caerostris sexcuspidata'', also known as the common bark spider, is a species of spider that occurs in Southern Africa, and on islands off the east coast of Africa, such as Madagascar, the Comores and Aldabra Island Aldabra is the world's second-largest coral atoll, lying south-east of the continent of Africa. It is part of the Aldabra Group of islands in the Indian Ocean that are part of the Outer Islands of the Seychelles, with a distance of 1,120 k .... It is a mainly nocturnal orb-web spider, the female constructing a large orb web stretching between trees or shrubs. During daylight hours she dismantles her web and retires to a nearby branch, tucking her legs, which are covered with fine hair, against her body, to blend with the surroundings to resemble part of a branch, complete with growth bulges. Though mainly nocturnal, these spiders may be found on their webs in shady, forested areas during the day. The dorsal surface is cryptically coloured with horny projecti ...
