Pinniped feeding

Webb1 juni 2006 · Pinniped have evolved a range of reproductive and foraging patterns to deal with the constraint of terrestrial parturition and marine feeding. To understand the link between these constraints it is necessary to understand both reproductive periods on land and foraging at sea.

Pinnipeds , commonly known as seals, are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic, mostly marine mammals. They comprise the extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals).

Webb9 dec. 2015 · Filter feeding is another specialized feeding strategy used by one extant pinniped species, the crabeater seal (Taylor, 1987; Adam & Berta, 2002; Jones & Goswami, 2010). Filter feeders engulf water with high concentrations of small prey, and water is then expelled from the sides of the mouth, trapping prey inside the oral cavity (Taylor, 1987).
