Marine mammals often forage in dark or turbid waters. Whereas dolphins use echolocation under such conditions, pinnipeds apparently lack this sensory ability. For seals hunting in the dark, one source of sensory information may consist of fish-generated water movements, which seals can detect with their highly sensitive whiskers. Water movements in the wake of fishes persist for several minutes. Here we show that blindfolded seals can use their whiskers to detect and accurately follow… Expand
Hydrodynamic Perception in Seals and Sea Lions
TLDR
In the course of pinniped evolution at least two types of whiskers evolved that realized different mechanisms for the reception of external hydrodynamic information. Expand
Tracking of biogenic hydrodynamic trails in harbour seals (Phoca vitulina)
TLDR
A harbour seal was trained to swim predefined courses, thus generating biogenic hydrodynamic trails, which were measured using Particle Image Velocimetry and showed search patterns either mostly congruent with the trail or crossing the trail repeatedly in an undulatory way. Expand
Hydrodynamic Perception in Pinnipeds
The vibrissal system of pinnipeds such as harbor seals (Phoca vitulina) or California sea lions (Zalophus californianus) serves not only for the detection and identification of objects by directExpand
Hydrodynamic reception in the Australian water rat, Hydromys chrysogaster
TLDR
It is shown that Hydromys can detect water motions with its whiskers, and no responses to surface waves generated by a vibrating rod and resembling the surface waves caused by struggling insects were found. Expand
Hydrodynamic trail following in a California sea lion (Zalophus californianus)
TLDR
The results of this study are consistent with the hypothesis that structural differences in the vibrissal hair types of otariid compared to phocid pinnipeds lead to different sensitivity of the vibrISSae during forward swimming, but still reveal a good performance even in the species with non-specialized hair type. Expand
Harbor seal vibrissa morphology suppresses vortex-induced vibrations
TLDR
Using force measurements, flow measurements and numerical simulations, it is found that the dynamic forces on harbor seal whiskers are, by at least an order of magnitude, lower than those on sea lion whiskers, which do not share the undulated structure. Expand
Hydrodynamic sensory threshold in harbour seals (Phoca vitulina) for artificial flatfish breathing currents
TLDR
This study is the first to assess a sensory threshold of the vibrissal system for a moving harbour seal under near-natural conditions and was defined for a natural type of stimulus differing from classical dipole stimuli which have been widely used in threshold determination so far. Expand
Hydrodynamic detection and localization of artificial flatfish breathing currents by harbour seals (Phoca vitulina)
TLDR
By creating near-natural conditions, this study shows that harbour seals have the ability to detect a so-far overlooked type of stimulus, as fish emit water currents through their gill openings, providing a source of sensory information for seals in the detection of prey fish. Expand
Are Vibrissae Viable Sensory Structures for Prey Capture in Northern Elephant Seals, Mirounga angustirostris?
TLDR
To test the hypothesis that northern elephant seals have increased innervation as other pinnipeds, vibrissae from the ventral‐caudal mystacial field from nine individuals were sectioned and stained for microstructure (trichrome) and innervation (Bodian silver stain) and the results add to the growing body of evidence that phocids, and perhaps all pinnIPeds, possess highly sensitive mystacial vibrISSae that detect prey.

Foraging tactics of Baikal seals differ between day and night
Some pinniped species appear to forage during both daylight and darkness. To deter- mine any differences in the foraging tactics between day and night, we attached data loggers with a newly developedExpand

TLDR
The hunting behavior of a marine mammal was studied beneath the Antarctic fast ice with an animal-borne video system and data recorder to highlight the broad range of insights possible with simultaneous recordings of video, audio, three-dimensional dive paths, and locomotor effort. Expand
DARK ADAPTATION AND VISUAL SENSITIVITY IN SHALLOW AND DEEP‐DIVING PINNIPEDS1
TLDR
It is concluded that elephant seals are sufficiently adapted to rely on vision underwater, even while diving to depths in excess of 1000 meters where bioluminescence may be the sole source of ambient light. Expand

TLDR
Measurements in a man-made open-air pond showed that water velocities in a quasi-natural still water environment can be as small as 1 mm s(-)(1) as long as no moving animal was present in the measuring plane. Expand

TLDR
The kinematic analysis indicates both sequential and simultaneous taxis mechanisms are used by Temora to follow the odour signal, and copepods appear to use mechanisms that are similar to those employed by trail-following terrestrial insects such as ants. Expand
