By Friedrich G. Barth
Spiders are magnificent creatures. Their diversified and intricate diversity of habit and hugely constructed sensory structures are excellently tailored to the environmental stipulations - as is confirmed through their evolutionary luck. Over four hundred million years, spiders have built their sensory organs to a desirable technical perfection and complexity.
In his fascinating e-book, Professor Friedrich G. Barth places this technical perfection into the context of "biology", during which the interplay among surroundings and sensory organs and the selectivity of the senses as a hyperlink among atmosphere and behaviour play an important position.

Reclusa) but particularly widespread in South America; its poison has a cytotoxic and hemolytic action. • Phoneutria (Ctenidae), of Central and South America, the toxin of which is a particularly effective nerve poison that causes fatal paralysis (Plate 11). • Harpactirella (Barychelidae, Mygalomorphae), called "baboon spiders" by the locals; a dangerous South African species belongs to this genus. In the publications by Maretic (1987) and by Bettini (1978) the interested reader will find more about the pharmacology and clinical aspects of spider poisons and bites.
