Antarctic krill (Euphausia superba) is a species of krill found in the Antarctic waters of the Southern Ocean. It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 animals per cubic metre. [3]

Antarctic krill (Euphausia superba) is a species of krill found in the Antarctic waters of the Southern Ocean. It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 individual animals per cubic metre.

2023年8月11日 · As a keystone species, Antarctic krill provide the basis of the diet for most marine mammals and seabirds and play a critical role in drawing down and storing vast quantities of carbon in the Southern Ocean.

The Antarctic krill is an extremely common, pelagic crustacean native to the waters surrounding Antarctica and is one of the most important prey species near the bottom of Southern Ocean food webs.

1 天前 · "Antarctic krill are the superheroes of the Southern Ocean," said Rod Downie, chief polar adviser at the wildlife charity WWF-UK. "They are tiny, unsung heroes that sustain incredible marine life ...

Antarctic krill is one of the most abundant and successful animal species on the planet. They are frequently found in such abundance that they colour the sea a reddish-brown. They may be small individually, but there is an estimated 400 million tonnes of Antarctic krill in the Southern Ocean.

2024年11月1日 · Rising temperatures are putting the future of Antarctic krill at risk. Numbering in the trillions and collectively weighing hundreds of millions of tonnes, Antarctic krill are among the most numerous animals on Earth. But rising ocean temperatures are causing the krill’s habitat to shrink, forcing populations to contract towards the South ...

2023年6月29日 · Introducing Antarctic Krill. Antarctic krill are small sea creatures that grow no bigger than a human thumb but can do amazing things. For example, they glow in the dark and they can shrink or grow by replacing their skeletons, which are on the outside of their bodies.

Antarctic krill are sensitive to climate change and its impacts – from rising temperatures, sea-ice loss and ocean acidification driven by increasing concentrations of carbon dioxide in seawater. Krill are also the target of a rapidly growing commercial fishery in the Southern Ocean.

Antarctic krill are a key species, supporting populations of penguins, seals, whales and other marine life. It is estimated that in one day, a single crabeater seal can consume 11,000 krill, and a single Adélie penguin can consume 1,200 krill!
