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] |
Nesticidae
Scaffold web spiders (Nesticidae) is a family of araneomorph spiders closely allied with tangle web spiders. Like the "Theridiidae", these spiders have a comb of serrated bristles on the hind tarsi that are used to pull silk bands from the spinnerets. It contains 16 genera and about 300 species, many of which are associated with caves or overhangs. The genus ''Nesticus'' is the type for the family and is found throughout the world. The related '' Eidmannella'' has speciated considerably in Texas caves and includes some extremely localized species that are considered threatened. One species, ''Eidmannella pallida'', is found in caves and under overhangs, but also in agricultural fields and other habitats away from such restricted areas. The genus '' Carpathonesticus'' is found in central Eurasia. Genera , the World Spider Catalog accepts the following genera: *'' Aituaria'' Esyunin & Efimik, 1998 — Ukraine, Russia, Georgia *'' Canarionesticus'' Wunderlich, 1992 — Canary Is. * ...

Spiders Of Canada
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 separate th ...
