Additionally spiders have pedipalps (or just palps), which are two appendages next to their mouths that aid in manipulating food and are used by the males in mating.
Spiders often use elaborate mating rituals (especially in the visually advanced jumping spiders) to allow the male to approach close enough to inseminate the female without triggering a predatory response.
While venom from either spider can be deadly to children and the infirm, since the development of antivenin to the venoms of both were developed (the funnel web spider in the mid-1980's and the wandering spider in 1996), no humans have died from their bites.

The woodlouse hunters, sowbug-eating spiders or cell spiders, family Dysderidae, are Araneomorphae spiders found primarily in Eurasia, though extending into North Africa.
One species, Dysdera crocata (the woodlouse hunter), has been transported over much of the planet together with its preferred foods - sowbugs and pillbugs (or woodlice).

The spider anatomy, respiration-wise, is based upon a tracheal system, with each opening to the trachea as extensions of outer pores reaching from the spider abdomen, protected by spiracles which are pores in the spider exoskeleton, composed of chitin.
Spiders reproduce by eggs laid in silk bundles called egg sacs, and the male (usually significantly smaller than the female down to 1% for Tidarren sisyphoides) is likely to be killed by the female after the coupling, or sometimes before intercourse has occurred.
Normally, fl widow spider bites are fatal only to children, due to the fact that children have much smaller body weights than adults and so the poison is more concentrated in their bodies when a bite does occur.
