	Systematics of the Arachnida
		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).
		For more information on arachnids on the WWW, try the Arachnida pages at the Tree of Life, or visit the very comprehensive arachnology home page at Antwerp University in Belgium and this fine Arachnida Sources Listing.

	ADW: Arachnida: Information
		The Arachnida also includes a diverse array of smaller groups, including scorpions (1200 species), whip scorpions (100 species), palpigrades (60 species), pseudoscorpions (2000 species), solpugids (900 species), and harvestmen (5000 species).
		Arachnids have a pair of tagmata called a prosoma and opisthosoma.

	Arachnida - LoveToKnow 1911
		The Arachnida form a distinct class or line of descent in the grade Euarthropoda, diverging (perhaps in common at the start with the Crustacea) from primitive Euarthropods, which gave rise also to the separate lines of descent known as the classes Diplopoda, Crustacea, Chilopoda and Hexapoda.
		The coxal glands of the Arachnida are structures of the same nature as the green glands of the higher Crustacea and the so-called " shell glands " of the Entomostraca.
		Little is known of the form of the appendages in the lowest archaic Arachnida, but the tendency of those of the prosomatic somites has been (as in the Crustacea) to pass from a generalized bi-ramose or multi-ramose form to,that of uni-ramose antennae, chelae and walking legs.

		The coxal glands of the Arachnida are structures of the same nature as the green glands of the higher Crustacea and the so-called " shell glands " of the Entomostraca.
		The coxal glands are the chief excretory organs of the Arachnida.
		Other Arachnida achieve dispersal by clinging to the legs of insects, like the common British Mite Belaustium nemorum which is often to be found on the legs of Tipulidea, and the Uropod Mites which attach themselves by a thread of their own excrement to the bodies of beetles.

		The endosternite in Arachnida is a cartilaginous plate, slightly chitinised, lying between the nerve ganglia and the alimentary canal.

		This is according to the manager of the South African National Survey of Arachnida (Sansa), Professor Ansie Dippenaar-Schoeman, who has been working with these eight-legged creatures for the past 40 years.
		While spiders, scorpions, mites and ticks are all arachnida, according to the professor, who works at the Agricultural Research Council Plant Protection Centre, spiders are most important because they eat insects which can destroy crops.
		She said the country was home to more than 5000 species of arachnida, many of which were important to the environment or needed to be studied because of their poisons.

		Within the class Arachnida the spiders belong to the order called Araneae.
