Document Summary
Taxonomy: science of identifying and classifying different organisms based on similar characteristics. Grouping species based on similiar characteristics which means it hierarchical. Genus is always capitalized whereas the species name is not capitalized, both always italicized. Monophyly: derived (=evolved) from a single common ancestor. A monophylectic group: only and all closely related species. A monophylectic trait is a trait that would be shared among all species such as wings in insects. Australia has some snake sized earthworms, glimpse of the past. Breathe through trachea, have airholes to take in air to breathe. Pedipalps, behind the mouth, usually associated with sensation. Scorpions light up in the dark, due to fluorescent chemicals inside scorpions. Many are toxic, but very few have venom harmful to humans, e. g. mouse spiders, venomous but only painful. Black widow spider bites, highly venomous and only deadly if not treated with anti- venom. Brown recluse spider, most deadly spider in north america, deadly if provoked.
