- Ambient temperature does not affect the tactile sensitivity of mystacial vibrissae in harbour sealsG Dehnhardt
University of Bonn, Department of Zoology, Poppelsdorfer Schloss, D 53115 Bonn, Germany and University of Joensuu, Department of Biology, PO Box 111, SF 80101 Joensuu, Finland
J Exp Biol 201:3023-9. 1998..This suggests that, in the vibrissal follicles of harbour seals, no vasoconstriction occurs during cold acclimation, so that the appropriate operating temperature for the mechanoreceptors is maintained...

- Hydrodynamic trail-following in harbor seals (Phoca vitulina)G Dehnhardt
Institut fur Zoologie, Universitat Bonn, Poppelsdorfer Schloss, D 53115 Bonn, Germany
Science 293:102-4. 2001..Here we show that blindfolded seals can use their whiskers to detect and accurately follow hydrodynamic trails generated by a miniature submarine. This shows that hydrodynamic information can be used for long-distance prey location...
