Sensationalised stories about the bite of Steatoda nobilis have featured in UK newspaper articles. [38] [39] Stuart Hine from the Natural History Museum, London responded on the naturenet blog, stating, "Of course I also explain the great value of spiders and how rare the event of spider bite in the UK actually is. I also always explain that up ...
Phoneutria nigriventer, the Brazilian wandering spider (a ctenid spider) is a large brown spider similar to North American wolf spiders in appearance, although somewhat larger. It has a highly toxic venom and is regarded (along with the Australian funnel-web spiders ) as among the most dangerous spiders in the world. [ 6 ]
Cave spiders feed on smaller invertebrates, most frequently myriapods and slugs. [6] The European cave spider is not dangerous to humans and although (in common with nearly all spiders) they have venom, its effect on large mammals is negligible. They are unlikely to bite if carefully handled but if sufficiently provoked they are capable of ...
However, brown recluse venom is significantly dangerous to humans, while that of the huntsman spider is less so. [7] On their upper surfaces the main colours of huntsman spiders are inconspicuous shades of brown or grey, but many species have undersides more or less aposematically marked in black-and-white. [8]
Similar to those of other recluse spiders, their bites sometimes require medical attention. The brown recluse is one of three spiders in North America with dangerous venom, the others being the black widow and the Chilean recluse. Brown recluse spiders are usually between 6 and 20 millimetres (0.24 and 0.79 in), but may grow larger.
Giant house spiders may compete with hobo spiders for the same resources. Hobo spiders grow no more than a body size of 15 millimeters (0.59 in) long whereas the larger female giant house spider can have a body size of 18 millimeters (0.71 in), [ 15 ] but has proportionately much longer legs.
A spider bite, also known as arachnidism, is an injury resulting from the bite of a spider. The effects of most bites are not serious. [1] Most bites result in mild symptoms around the area of the bite. [1] Rarely they may produce a necrotic skin wound or severe pain. [2]: 455 Most spiders do not cause bites that are of importance.

The spider usually strikes from a distance of 10 to 20 millimetres (0.39 to 0.79 in) and the entire attack sequence only lasts 1/700th of a second. [5] After making the capture, the spider typically bites the prey with venomous effect, and wraps it in the normal spider fashion with silk from the spinnerets.
