Spider taxonomy is the part of taxonomy that is concerned with the science of naming, defining and classifying all spiders, members of the Araneae order of the arthropod class Arachnida, which has more than 48,500 described species.

Many spider species are colored so as to merge with their most common backgrounds, and some have disruptive coloration, stripes and blotches that break up their outlines. In a few species, such as the Hawaiian happy-face spider, Theridion grallator , several coloration schemes are present in a ratio that appears to remain constant, and this may ...

The family was first circumscribed by Eugène Simon in 1876, but was later made synonymous with Pisauridae and Bradystichidae. It was restored to family level and redefined in 2025 based on a phylogenetic study of Pisauridae that found the family to be paraphyletic. [3]
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. [2] As of December 2023, 1,100 species have been identified, with 166 genera. [3] The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas".
In most species the males have a spur on their legs, which is used to immobilise the female and prevent her from biting during the mating process. The lateral posterior spinnerets are elongated. [5] The oldest known idiopid, Number 16, died at the age of 43 years. [6]
