The '''[[crabeater seal]]''' (''Lobodon carcinophaga'') 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. While population estimates are uncertain, there are at least 7 million and possibly as many as 75 million individuals. This success of this species is due to its specialized predation on the abundant [[Antarctic krill]] of the [[Southern Ocean]], for which it has uniquely adapted, sieve-like tooth structure. Indeed, its scientific name, translated as "lobe-toothed (''lobodon'') crab eater (''carcinophaga'')", refers specifically to the finely lobed teeth adapted to filtering their small crustacean prey.
'''[[Antarctic krill]]''' is a species of [[krill]] found in the [[Antarctica|Antarctic]] waters of the [[Southern Ocean]]. It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 individual animals per cubic meter. It feeds directly on minute phytoplankton, thereby using the primary production energy that the phytoplankton originally derived from the sun in order to sustain their open ocean life cycle.


Despite its name, crabeater seals do not eat crabs. As well as being an important [[krill]] predator, the crabeater seal is an important component of the diet of [[leopard seal|leopard seals]] (''Hydrurga leptonyx''), which consume about 80% of all crabeater pups.

Antarctic krill is a species of krill found in the Antarctic waters of the Southern Ocean. It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 individual animals per cubic meter. It feeds directly on minute phytoplankton, thereby using the primary production energy that the phytoplankton originally derived from the sun in order to sustain their open ocean life cycle.

It grows to a length of 6 cm, weighs up to 2 grams, and can live for up to six years. It is a key species in the Antarctic ecosystem and is, in terms of biomass, probably the most abundant animal species on the planet. In 2019, the Antarctic krill was featured on a stamp of Westarctica to celebrate its role as a vital part of the Antarctic ecosystem.
