Krill species[edit]
Krill are small crustaceans that can be found in all the world’s oceans, but mostly in the Northern (Arctic) and Southern (Antarctic) polar seas. They belong to the same animal family as shrimp, lobsters and crabs. There are more than 80 different known krill species. Among these, the Antarctic krill, called Euphausia superba, is the kind of krill that can be fished, because it lives in large swarms and swims in open water. Krill swim in huge swarms that can be stretch for several kilometers in length and have a density of up to one million individuals per cubic meter.[2]
