The Antarctic krill ( " Euphausia superba " ) is one of the most abundant animal species on earth, with a biomass of around 500 million tonnes.

In the Southern Ocean, one species, the Antarctic Krill, Euphausia superba, makes up a biomass of hundreds of millions of tonnes, similar to the entire human consumption of animal protein.
8.
The annual catch of " Euphausia superba " since the mid-1990s is about 100 120, 000 tonnes annually, i . e ., about one fiftieth of the CCAMLR catch quota.

Antarctic krill ( " Euphausia superba " ), southern elephant seal ( " Mirounga leonina " ) pups and seabirds other than penguins have also been found in leopard seal scats in small quantities.
