'''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.
The '''[[Brown Skua]]''' is a large seabird that breeds in the subantarctic and [[Antarctica|Antarctic]] zones and moves further north when not breeding.


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.
Brown skuas are masters of piracy, they often feed by stealing partially digested fish from the the beaks of other birds. Their victims are typically terns or [[penguin]]s, though other fish-eating species are also pursued until they disgorge their catches. The fact that skuas are swift and agile fliers (and that they sometimes gang up on a single victim) aid in their success rate. This is the heaviest species of skua and rivals even the largest gulls as the heaviest species in the shorebird order although not as large in length or wingspan.

The Brown Skua is a large seabird that breeds in the subantarctic and Antarctic zones and moves further north when not breeding.

Brown skuas are masters of piracy, they often feed by stealing partially digested fish from the the beaks of other birds. Their victims are typically terns or penguins, though other fish-eating species are also pursued until they disgorge their catches. The fact that skuas are swift and agile fliers (and that they sometimes gang up on a single victim) aid in their success rate. This is the heaviest species of skua and rivals even the largest gulls as the heaviest species in the shorebird order although not as large in length or wingspan.
