Krills are small crustaceans of the order Euphausiacea, and are found in all the world's oceans.

InformationEdit

In the Real WorldEdit

Meganyctiphanes norvegica2

Northern Krill

The lowly krill averages only about two inches (five centimeters) in length, but it represents a giant-sized link in the global food chain. These small, shrimp-like crustaceans are essentially the fuel that runs the engine of the Earth’s marine ecosystems.

Krill feed on phytoplankton, microscopic, single-celled plants that drift near the ocean’s surface and live off carbon dioxide and the sun’s rays. They in turn are the main staple in the diets of literally hundreds of different animals, from fish, to birds, to baleen whales.

Simply put, without krill, most of the life forms in the Antarctic would disappear.

Alarmingly, there are recent studies that show Antarctic krill stocks may have dropped by 80 percent since the 1970s. Scientists attribute these declines in part to ice cover loss caused by global warming. This ice loss removes a primary source of food for krill: ice-algae.

Pink and opaque, Antarctic krill are among the largest of the 85 known krill species. Their estimated numbers range from 125 million tons to 6 billion tons in the waters around Antarctica. During certain times of year, krill congregate in swarms so dense and widespread that they can be seen from space.

Antarctic krill can live up to 10 years, an amazing longevity for such a heavily hunted creature. They spend their days avoiding predators in the cold depths of the Antarctic Ocean, some 320 feet (100 meters) below the surface. During the night, they drift up the water column toward the surface in search of phytoplankton.

In the Happy Feet franchiseEdit

In Happy Feet Two, they appear mailnly as two friends, Will and Bill. The swarm they belong to seem to have helped in the breaking the Doomberg during the "Under Pressure" sequence.

TriviaEdit

  • A shrimp in Happy Feet (video game)
    In the franchise, the looks of an krill is similar to a shrimp appearing in Happy Feet: The Videogame.
  • In Happy Feet Two, after the Krill escape the whales attack, if you pause when the whales are attacking the rest of the Krill swarm (as seen by Bill and Will), the shape of the swarm with the holes caused by the whales is that of a skull or a ghost face, call it what you will.
