The only spiders of real medical importance to humans in the United States are the Loxosceles and Latrodectus species, primarily the brown recluse and the black window, respectively. These spiders bite humans only when trapped or crushed against the skin.

Spider bites represent an unusual and potentially over-represented clinical diagnosis. Despite a common fear of spiders, known as arachnophobia, current knowledge suggests that only a small number of families within the order Araneae are medically relevant.

Spiders are a source of intrigue and fear, and several myths exist about their medical effects. Many people believe that bites from various spider species cause necrotic ulceration, despite evidence that most suspected cases of necrotic arachnidism are caused by something other than a spider bite.

Spider Venoms and Spider Toxins
Journal of Toxicology: Toxin Reviews, 1998AbstractSpider venoms and toxins are useful tools for the study of ion channels and synaptic functions of neurons in vertebrates and invertebrates. The components of spider venom, such as proteins, peptides, polyamines and bioamines, are species-specific. The various functions of these toxins are reviewed in this paper.

The article discusses a study from researchers such as Oswald Schmitz of Yale University that indicates that the carbon dioxide storage rates of plants in environments with herbivores and predators are higher than those of plants in environments without herbivores and predators.

Current Opinion in Neurobiology, 2004
Spiders have highly developed mechanosensory systems, some of which provide access to forms of stimulation alien to our own sensations. Studies of hair-shaped air movement detectors (trichobothria) and tactile sensors have uncovered an outstanding refinement of the processes of stimulus uptake and stimulus transformation, which reflect details of both ...

Behavioural Processes, 2005
Simple heuristics may help explain how even a spider, despite its minute brain, can be disturbingly intelligent. Hutchinson and Gigerenzer suggest that the generalist-specialist distinction (or more accurately the predictability-unpredictability distinction) may be related to a species' level of reliance on simple heuristics, and spider behaviour may ...

The article discusses the lengths that some species of arachnids will go to mimic the appearance and behavior of ants, such as the genus of jumping spider called Myrmarachne. According to the report, species that masquerade as ants are the most common type of mimicry, but are the least understood.

Biological Reviews, 2010
Over the last three decades, the fossil record of spiders has increased from being previously biased towards Tertiary ambers and a few dubious earlier records, to one which reveals a much greater diversity in the Mesozoic, with many of the modern families present in that era, and with clearer evidence of the evolutionary history of the group.
