Rare video of Antarctic krill swimming

Wikipedia:

In the Southern Ocean, one species, the Antarctic krill, Euphausia superba, makes up an estimated biomass of over 500 million tonnes, roughly twice that of humans. Of this, over half is eaten by whales, seals, penguins, squid and fish each year, and is replaced by growth and reproduction. Most krill species display large daily vertical migrations, thus providing food for predators near the surface at night and in deeper waters during the day.
 Because krill oil is said to be a good source of the omega 3 oils DHA and EPA, there is an emerging market for krill oil as a dietary supplement ingredient. Which might or might not be a good thing, as the use of fish for omega 3 supplements has led to overfishing.
