Wandering Spider

	Wandering Spider Wandering spiders (''Ctenidae'') are a family of spiders that includes the Brazilian wandering spiders. These spiders have a distinctive longitudinal groove on the top-rear of their oval carapace similar to those of the Amaurobiidae. They are highly defensive and venomous nocturnal hunters. Wandering spiders are known to hunt large prey, for example hylid species '' Dendropsophus branneri.'' Despite their notoriety for being dangerous, only a few members of '' Phoneutria'' have venom known to be hazardous to humans, but the venoms of this family are poorly known, so all larger ctenids should be treated with caution.

	Ctenus ''Ctenus'' is a genus of wandering spiders first described by Charles Athanase Walckenaer in 1805. It is widely distributed, from South America through Africa to East Asia. Little is known about the toxic potential of the genus ''Ctenus''; however, '' Ctenus medius'' has been shown to share some toxic properties with '' Phoneutria nigriventer'', such as proteolytic, hyaluronidase and phospholipase activities, in addition to producing hyperalgesia and edema. The venom of ''C. medius'' also interferes with the complement system in concentrations in which the venom of ''P. nigriventer'' is inactive, indicating that some species in the genus may have a medically significant venom. The venom of ''C. medius'' interferes with the complement component 3 (C3) of the complement system; it affects the central factor of the cascades of the complement, and interferes with the lytic activity of this system, which causes stronger activation and consumption of the complement components.
