As deserts are harsh biological environments with little water and extreme (hot and cold) temperatures, biological organisms require unique adaptations to cope with the extreme environment. These adaptations can range from methods to minimise water loss, efficient heat
exchange systems, methods to immobilise prey, and systems to prevent predators and other animals from consuming them. The purpose of this website is to provide basic information on the toxins that are produced in desert environments. In addition to biological toxins (and venoms) which are found in deserts, minerals which, when mined and concentrated, can be hazardous to human health are briefly mentioned.
