The Canadian Arachnologist is a collaborative effort of biologists and enthusiasts devoted to the study of spiders, mites, pseudoscorpions and other members of the Class Arachnida.

Participants create autobiographical sketches, upload collection records and author/review descriptions in The Nearctic Spider Database.

Ideas are debated and news is shared in The Nearctic Arachnologists’ Forum and a freely-distributed annual newsletter with feature articles is produced.
