Antarctic krill are small, shrimp-like crustaceans that live in huge swarms in the Southern Ocean. They are a vital food source for many marine animals, including whales, seals, and penguins. Krill feed on phytoplankton and play a key role in the Antarctic ecosystem by cycling nutrients. They are also harvested for use in supplements and aquaculture feed.
