Vibration Sensitivity in an Orb-weaver

DOI: http://dx.doi.org/10.1093/icb/12.3.539 539-543 First published online: 1 August 1972


Electrophysiological activity is recorded from the ventral nerve mass of A. diadematus in response to direct vibration of the leg. Measurements taken under varied frequcncy and intensity conditions indicate that response maxima are in the region of 100 hertz with a threshold sensitivity less than 100 Å. The frequency response of the spiders leg does not correspond well to the frequency response of its web in a sound field.
