Alongside the use of the web to capture other prey, the spiders are also cannibals and prey on each other, but this only happens just before, during, or just after sexual activity. They attack based on their size, sexual experience, and hunger levels. A. diadematus is a reclusive creature and only bites humans if cornered or otherwise provoked ...
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.

Nyssus coloripes, known commonly in Australia as the orange-legged swift spider, but also as the spotted ground swift spider, the fleet footed spider and the painted swift spider, [2] is a spider belonging to the family Corinnidae. It is found commonly in Australia and New Zealand.
While roughly 3,000 species of spiders are found throughout the U.S., very few pose a direct threat to humans. Spider bites are rare, and medically significant incidents are even less common ...
A number of spiders can cause spider bites that are medically important. Almost all spiders produce venom but only a few are able to cause significant harm to humans. [1] Two medically important spider genera have a worldwide distribution—Latrodectus and Loxosceles. Others have a limited distribution.
Scytodidae spiders are haplogyne, meaning they lack hardened female genitalia. They have six eyes, like most spiders in this group, arranged in three pairs. They possess long legs and a dome-shaped cephalothorax, and are usually yellow or light brown with black spots or marks. Their domed head and three eye groups tend to resemble a human skull ...
Pisaurina mira, as one of the most common spiders found in eastern United States, is well integrated in human lives. While the venom of P. mira is lethal to its prey, it is not effective against larger targets and is thus very unlikely to be medically significant for humans.
The webs are oriented vertically and have a "signal" thread attached to the center that notifies the spider when prey has been captured. Unlike Argiope garden spiders, Araneus marmoreus hides in a silken retreat to the side of the web (at the end of the signal thread). The retreat can be made from leaves folded over and held together with silk ...
