Paintings of Araneus angulatus from Svenska Spindlar of 1757, the first major work on spider taxonomy. 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.

Mites are tiny members of the class Arachnida; most are in the size range 250 to 750 μm (0.01 to 0.03 in) but some are larger and some are no bigger than 100 μm (0.004 in) as adults. The body plan has two regions , a cephalothorax (with no separate head) or prosoma, and an opisthosoma or abdomen.
Chelicerates comprise four classes of arthropod, with similar gross morphology but defining differences: Class Xiphosura (horseshoe crabs); class Eurypterida (the extinct eurypterids); class Arachnida (spiders, scorpions, ticks and mites); and class Pycnogonida (sea spiders).
Some species of amblypygids, particularly Phrynus marginemaculatus and Damon diadema, may be among the few examples of arachnids that exhibit social behavior. Research conducted at Cornell University suggests that mother amblypygids communicate with their young with her antenniform front legs, and the offspring reciprocate both with their ...
