Robertus Cantabricus
''Robertus cantabricus'' is a spider in the family Theridiidae. The scientific name of this species was first published in 1931 by Jean-Louis Fage Jean-Louis Fage (30 September 1883, in Limoges – 1964, in Dijon) was a French marine biologist and arachnologist.

Jean-Louis Fage
Jean-Louis Fage (30 September 1883, in Limoges – 1964, in Dijon) was a French marine biologist and arachnologist. A native of Limoges, he studied biology at the Sorbonne and in the laboratory at Saint-Vaast-la-Hougue. In 1906 he obtained his doctorate with a thesis on the nephridia of polychaetes. For the next fourteen years he served as a naturalist at the '' Laboratoire de biologie marine'' in Banyuls-sur-Mer. From 1920 he worked in the zoology department at the ''Muséum national d'histoire naturelle'' in Paris, where in 1938 he succeeded Charles Joseph Gravier (1865–1937) as professor and director of the department of zoology (worms and crustaceans). Fage made contributions in the fields of carcinology (study of crustaceans), arachnology and speleology. In 1945 he was a founding member of the ''Commission de spéléologie'' (being part of the ''Centre national de la recherche scientifique'' – CNRS). He also performed research of '' Ellobiopsis'' (genus of parasitic prot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a sep ...

Theridiidae
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of Araneomorphae, araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genus, genera, and is the most common arthropod found in human dwellings throughout the world. Theridiid spiders are both Entelegynae, entelegyne, meaning that the females have a genital plate, and Cribellum, ecribellate, meaning that they spin sticky capture silk instead of woolly silk. They have a comb of serrated bristles (setae) on the Arthropod leg, tarsus of the fourth leg. The family includes some model organisms for research, including the List of medically significant spider bites, medically important Latrodectus, widow spiders. They are important to studies characterizing their venom and its clinical manifestation, but widow spiders are also used in research on spider silk and sexual biology, including ...
