Harbour seals possess highly sensitive vibrissae that enable them to track hydrodynamic trails left behind by a swimming fish. Most of these contain vortex rings as main component. They may reveal information about their generator the differ depending on fish species, fish's body shape, size and style. In addition, generate single in diverse natural situations. this study, ability blindfolded stationary harbour detect analyse regarding directional has been investigated. three different...
Abstract Whiskers (vibrissae) are important tactile sensors for most mammals. We introduce a novel approach to quantitatively compare 3D geometry of whisker arrays across species with different numbers and arrangements, focusing on harbor seals ( Phoca vitulina ), house mice Mus musculus ) Norway rats Rattus norvegicus ). all three decrease in arclength increase curvature from caudal rostral. They emerge the face elevation angles that vary linearly dorsoventral position, orientations...
ABSTRACT Harbour seals are known to be opportunistic feeders, whose diet consists mainly of pelagic and benthic fish, such as flatfish. As flatfish often cryptic do not produce noise, we hypothesized that harbour able detect localize using their hydrodynamic sensory system (vibrissae), fish emit water currents through gill openings (breathing currents). To test this hypothesis, created an experimental platform where artificial breathing current was emitted one eight different openings. Three...
Abstract Pinnipeds have vibrissae with which they can explore their environment. Two vibrissal parameters that differ in pinnipeds are shape and number. Regarding shape, most phocids undulated vibrissae, whereas the of a few phocids, all otariids walruses smooth. As there is disagreement respect to phocid lack undulation, we systematically collected information on type. We documented eared seals examined, walruses, Mediterranean monk seals, bearded, leopard smooth vibrissae. All other except...
