The American Arachnological Society (AAS) is a scientific organization founded in 1972 in order to promote the study of arachnids by seeking to achieve closer cooperation and understanding between amateur and professional arachnologists along with publication of the Journal of Arachnology.
There are characteristics that are particularly important for the terrestrial lifestyle of arachnids, such as internal respiratory surfaces in the form of tracheae, or modification of the book gill into a book lung, an internal series of vascular lamellae used for gas exchange with the air. [21]
