Wonders of Harbor and Grey Seal Whiskers: Morphology, Natural Frequencies, and 3D Modeling

Advanced Science, EarlyView.
Seals detect prey by sensing vortices using whiskers. How whisker morphologies and locations respond to hydrodynamic signals across various frequencies remains unclear. This study measures whiskers’ natural frequencies and morphologies and maps them to whisker locations on the muzzle, providing insights into how seals interpret hydrodynamic signals ...
