This lecture includes the natural history and biology of spiders including scorpions. It also touches on other arachnids such as Uropydgidae (whip Scorpions) and Amblypygids (tailless whip scorpions).
Arachnids are a diverse group of fauna. They all have eight legs, and two body segments, they can have from 0-8 eyes depending on species. All spiders are predators and most are venomous. The behavior of many species is nothing less than amazing.
