A spider bite is an injury resulting from the bites of spiders or other closely related arachnids.

Spiders are active hunters and rely heavily on their bites to paralyze and kill their prey before consuming it. They also bite in self-defense. While many spiders will never attack animals larger than themselves, some—e.g., Atrax robustus—exhibit a rather aggressive behavior and will stand their ground when approached by larger animals. Most spider bites occur when humans unintentionally press up against spiders and receive a defensive bite. On rare occasions, spiders may make prey mistakes and bite a human finger or other body part as though it were a caterpillar or other such insect.

Sicariidae

The brown recluse spider or violin spider, Loxosceles reclusa, Sicariidae (formerly placed in a family "Loxoscelidae") is a spider with a venomous bite.

Brown recluse spiders are usually between 6–20 mm (1⁄4 in and 3⁄4 in), but may grow larger. While typically light to medium brown, they range in color from cream-colored to dark brown or blackish gray. The cephalothorax and abdomen may not necessarily be the same color. These spiders usually have markings on the dorsal side of their cephalothorax, with a black line coming from it that looks like a violin with the neck of the violin pointing to the rear of the spider, resulting in the nicknames fiddleback spider, brown fiddler, or violin spider.

Spider taxonomy is the alpha taxonomy of the spiders, members of the Araneae order of the arthropod class Arachnida with about 40,000 described species. However there are likely many species that have escaped the human eye to this day, and many specimens stored in collections waiting to be described and classified. It is estimated that only one third to one fifth of existing species have been described.

Arachnology currently divides spiders into two suborders with about 38 superfamilies, and 111 families. Seven of the 111 families are incertae sedis, meaning that their placement into superfamilies is not agreed upon; several other families are not placed in any superfamily.
