- Detection and direction discrimination of single vortex rings by harbour seals (Phoca vitulina)
Summary: Harbour seals are able to detect a variety of different vortex rings and are capable of analysing the travel direction of a single vortex ring perceived by the mystacial vibrissae.
- Hydrodynamic sensory threshold in harbour seals (Phoca vitulina) for artificial flatfish breathing currents
Summary: Harbour seals can detect the water flow caused by breathing flatfish using their vibrissae. We assessed thresholds of 3.7 to 4.2 cm s−1 breathing current velocity at efficient swim speeds.
- Vibrissal sensitivity in a harbor seal (Phoca vitulina)
Summary: Psychophysical testing of vibration detection in the harbor seal demonstrates acute sensitivity of the vibrissal system.
