Krill, zooplankton and microbes intercept phytoplankton in the surface ocean and sinking detrital particles at depth, consuming and respiring this POC to CO 2 (dissolved inorganic carbon, DIC), such that only a small proportion of surface-produced carbon sinks to the deep ocean (i.e., depths > 1000 m). As krill and smaller zooplankton feed ...
Krill is a rich source of protein and omega-3 fatty acids which are under development in the early 21st century as human food, dietary supplements as oil capsules, livestock food, and pet food. [10] [11] [12] Most krill is processed to produce fish food for use in aquariums and aquacultures. The krill is sold freeze-dried, either whole or ...
Antarctic krill directly ingest minute phytoplankton cells, which no other animal of krill size can do. This is accomplished through filter feeding , using the krill's highly developed front legs which form an efficient filtering apparatus: [ 12 ] the six thoracopods (legs attached to the thorax ) create a "feeding basket" used to collect ...

Larger capelin also eat krill and other crustaceans. The capelin move inshore in large schools to spawn and migrate in spring and summer to feed in plankton rich areas between Iceland, Greenland, and Jan Mayen. The migration is affected by ocean currents. Around Iceland maturing capelin make large northward feeding migrations in spring and summer.
Krill feeding under high phytoplankton concentration (slowed down by a factor of 12) These are contrasting methods for the removal of food particles from a water flow: for example, by the gill rakers of fish, the baleen of whales , or the ostia of sponges .
Plankton can be divided into producers and consumers. The producers are the phytoplankton (Greek phyton = plant) and the consumers, who eat the phytoplankton, are the zooplankton (Greek zoon = animal). Jellyfish are slow swimmers, and most species form part of the plankton. Traditionally, jellyfish have been viewed as trophic dead ends.
Krill feeding in a high phytoplankton concentration (slowed by a factor of 12). Filter feeders are aquatic animals that acquire nutrients by feeding on organic matters, food particles or smaller organisms (bacteria, microalgae and zooplanktons) suspended in water, typically by having the water pass over or through a specialized filtering organ that sieves out and/or traps solids.
