'''Krill''' are small crustaceans of the order Euphausiacea, and are found in all the world's oceans. The name "krill" comes from the Norwegian word ''krill'', meaning "small fry of fish", which is also often attributed to species of fish. | |||
<p><small>Photographer: | Krill are considered an important trophic level connection – near the bottom of the food chain – because they feed on phytoplankton and (to a lesser extent) zooplankton, converting these into a form suitable for many larger animals for which krill make up the largest part of their diets. In the [[Southern Ocean]], one species, the [[Antarctic krill]], ''Euphausia superba'', makes up an estimated biomass of around 379,000,000 tonnes, making it among the species with the largest total biomass. Of this, over half is eaten by whales, seals, penguins, squid, and fish each year, and is replaced by growth and reproduction. | ||
