Systematics of the Arachnida - English
URL: http://www.ucmp.berkeley.edu/arthropoda/arachnidasy.html

The Arachnida include the terrestrial chelicerates that everyone is familiar with, and that nearly everyone would rather not be too familiar with: spiders (Araneae), ticks and mites (Acari), and scorpions (Scorpiones). Arachnids also include a number of less familiar taxa: Opiliones (harvestmen or daddy-longlegs); Thelyphonida (whip-scorpions); Pseudoscorpiones (false scorpions); and many others. Most are predators, and some are venomous. All are terrestrial, except for some mites and spiders that have become secondarily aquatic.

URL: http://animaldiversity.ummz.umich.edu/arthropoda/arachnida.html

This large Class of arthropods includes over 60,000 described species (and most likely a very large number of so-far undescribed ones). Spiders make up the majority of these (around 35,000 described species); with mites and ticks next largest (around 25,000 species). The Arachnida also includes a diverse array of smaller groups, including scorpions (1200 species), whip spiders (70 species), whip scorpions (100 species), palpigrades (60 species), pseudoscorpions (2000 species), solpugids (900 species), and harvestmen (5000 species). Nearly all species are terrestrial.
