Seal Whiskers Detect Vortex Ring Size to Foil Fish Escapes
Sensing the Splash: whiskers as a directional sensor New research shows that harbour seals may read a fleeing fish’s evasive maneuvers not just by tracking wakes, but by sensing the size of spinning vortex rings generated by the fish’s jets. When a fish darts away, it can produce two jets in opposite directions, often creating…

Seals’ whiskers may foil fish escapes by reading vortex rings
New findings: Seals’ whiskers detect vortex-ring cues in fish escapes In a surprising twist on the predator–prey chess game beneath the waves, a team from the University of Rostock has shown that harbour seals can pick out subtle differences in the size of vortex rings generated by escaping fish. Published in the Journal of Experimental…
