The dominant krill in the southern polar oceans is the Antarctic krill (Euphausia superba), which is up to 2.3 inches (6 cm) long and weighs about 0.035 ounces (1 g).
Krill spend their days in the dark depths of the ocean (about 320 feet = 100 m deep), safe from their major predators (like baleen whales and sea birds).
Krill are eaten by many organisms, including mussels, fish, squid, sea birds, and mammals (like baleen whales and some seals).

Krill convert energy from the primary producer level into a form that is useable by animals in the upper levels of the marine food web.
Krill often are referred to as “keystone” species because they play such an important role for many marine systems.
Because krill can increase and decrease their size, it can be difficult to determine their age or an age distribution from a population of animals.

 Antarctic Krill, the engine that powers the Antarctic ecosystem
The "zoo" means that they are animals, the "plankton" means that they float in the upper reaches of the water column and are at the mercy of the ocean currents, being able to change their position in the water column, but not able to swim against the current or migrate in the normal sense.
Krill rise and fall in the water column depending on the time of day, they drift around in swarms that are so large it difficult to imagine, so they are either not in a particular area at all or are present in unimaginably huge quantities.
There is a very complex ecology that has arisen involving krill and krill predators, with different species of predator feeding at different times of year at different depths and on different sizes and therefore age groups of krill.

This means that Antarctic krill emit a yellow-green light that is thought to either camouflage the krill's shadow or aid the krill in mating or schooling at night.
Krill are invertebrates that grow to about two inches in length and live in large schools, or swarms, as dense as 10,000 krill per cubic meter of water.
Meanwhile, as ocean temperatures rise and the Antarctic sea ice melts, research suggests that krill populations may decrease as the krill are out-competed by salps, barrel-shaped filter feeders that likewise eat phytoplankton and thrive in warmer water temperatures.

 Science Show - 1 July 2006  - Krill biology and behaviour
Robert King is a biologist who studies krill, the tiny shrimp-like marine invertebrates which are an important food source for some species of whales.
So we decided to build a purpose-built facility which maintains the krill at zero degrees but the researchers can live comfortable at about 15 to 18 degrees, which is much better for all the experimental equipment as well of course.
If krill didn't form these dense aggregations, there would be no whales because they simply couldn't pluck individual one-gram animals out of the sea.

 Ecology of Krill
Since there is interest in developing krill as an efficient source of food for humans, it is important to understand how they survive in their natural habitat and what role they fill in the polar ecosystem.
Krill are tiny, shrimplike organisims that live in the icy water of the polar regions.
One reason for the krill’s vertical migration is that the microalgae on which they feed flows with the high density brine along the underside of the ice until it becomes part of the water column.

 Turbulent times means krill help climate - life - 21 September 2006 - New Scientist
Krill — small shrimp-like invertebrates that feed on plankton — are capable of turning the calm nocturnal sea into a churning, frothing Jacuzzi, researchers report.
Although tiny, krill is present in such vast numbers in the world’s oceans that its biomass is at least equal to all the animal protein consumed by humans each year.
And they were much higher: the krill elevated the turbulence by 3 to 4 orders of magnitude, and increased mixing between water layers by a factor of 100.

 Time to Krill? crucial antarctic ecosystem threatened
It is the aggregating nature of krill that has enabled the baleen whales to evolve their feeding habits; if krill were any less dense, great whales would not be able to filter enough water to strain out sufficient prey, and their great size attests to the abundance of krill.
It is still uncertain whether krill populations drift with the currents or whether they are able to maintain self-sustaining populations in particular areas, and one of the major question marks hanging over their life history is what they do over winter.
Although the fishery for Antarctic krill is not turning out to be the cornucopia that many had imagined, it is also not turning out to be the environmental scourge that it had the potential to be; in fact, it may end up being the agent for the restoration of the Antarctic ecosystem.

 Krill Summary
Krill are crustaceans and have a chitinous exoskeleton made up of three segments: the cephalon (head), thorax, and the abdomen.
Many krill are filter feeders: their front-most extremities, the thoracopods, form very fine combs with which they can filter out their food from the water.
Most krill are swarming animals; the size and density of such swarms vary greatly depending on the species and the region.

 'Parachuting' krill may provide bumper carbon sink - life - 07 February 2006 - New Scientist
Antarctic krill appear to feed at the surface of the ocean and “parachute” down to deep waters more often than previously thought, a new study reveals, suggesting they take a bigger bite out of the carbon that contributes to global warming.
The more often the krill parachute down, the less of their faecal output remains near the surface, where bacteria are more likely to pick up the carbon it contains and cycle this back into the atmosphere, say the researchers.
Although krill are tiny creatures, they have power in numbers, so their behaviours have a global impact.

Hobart, Tasmania — Species near the top of the Antarctic food web, the Patagonian toothfish, and at the base, Antarctic krill, were a major focus of discussions at the two-week meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
There is a growing demand for Antarctic krill, a tiny shrimp-like crustacean, as fish feed for the booming aquaculture industry.
Initiated earlier this year, the krill project has two primary objectives: to manage krill using the same monitoring, control and surveillance measures as mandated for other fisheries; and to approve precautionary, ecosystem-based catch limits at sufficiently small scales to protect Antarctic species that are dependent on krill.

 EQUIPPED TO SURVIVE (tm) - Krill Lamps
The lit portion of the Krill is 2.75 inches (7 cm) in length, about.75 inches (19 mm) shorter than the lit length (liquid portion) of a standard chem-light when standing on end.
Kriana's literature claims the standard Krills meet the Mil-Spec minimums for chemiluminescent lamps (which specs are only 3.06 fL at 15 minutes for a 12 hour green lamp according to the literature supplied by Kriana) and that they are as bright as a chem-light after one hour's activation.
Note, however, that the illumination is consistent over most of the Krills' rated battery life, and then only dims a barely perceptible amount towards the end of their rated life, compared to the chem-lights that start to dim after a few hours and considerably so towards the end of their ratenvgd life.
