Lobodon carcinophaga (Crabeater Seal)

Synonyms: Lobodon carcinophagus

Wikipedia Abstract

The crabeater seal (Lobodon carcinophagus) is a true seal with a circumpolar distribution around the coast of Antarctica. They are medium- to large-sized (over 2 m in length), relatively slender and pale-colored, found primarily on the free-floating pack ice that extends seasonally out from the Antarctic coast, which they use as a platform for resting, mating, social aggregation and accessing their prey. They are by far the most abundant seal species in the world.
