Goniosoma spelaeum (Mello-Leitao 1932), a cavernicolous species in the Ribeira Valley, southeastern Brazil, was studied in the field and laboratory . The defensive behaviors were : nipping with the chelicerae ; delivery of a sharp pinch with the fourth coxae and femora ; rapidly running away ; dropping from the cave ceiling and remaining concealed against the substrate ; and emission of a chemical defense compound. The delivery mechanisms of the defensive secretion were either by spreading the… Expand
