Pinniped whiskers
Webb10 jan. 2013 · Seals, Sea Lions, and Walrus: Pinnipeds. Pinnipeds are carnivores that have adapted to an amphibious marine existence. They forage at sea but most come ashore or onto ice at some time of the year to mate, give birth, suckle their young, or to molt. Many of their anatomical features reflect compromises needed to succeed in both marine and ... Pinnipeds – comprising seals, sea lions and walruses – have the longest whiskers, aka vibrissae, of all mammals. Among them, the pinniped with the longest whiskers is the Antarctic fur seal ( Arctocephalus gazella) with an individual whisker length of 48 centimetres (18.8 inches) from base to tip recorded in a bull described in British ...
