Krill, which means "whale food" in Norwegian, are eucarid crustaceans divided into 2 families.
Krill have a hard exoskeleton, many legs (used for swimming and gathering food), and a segmented body. Females produce almost 1,000 eggs each summer; the eggs are laid at the surface, but fall to great depths.

Krill, one of the ocean's smallest animals, is dinner for one of its largest, whales! There are about 82 species of krill, ranging in size from less than a quarter of an inch long to two inches long. Krill are crustaceans like copepods.
KRILL
Krill are tiny animals, euphasiids, that float in the oceans. They are shrimp-like crustaceans that are found in vast amounts in the cold waters of the Arctic and Antarctic Oceans. Baleen whales eat krill that they sieve through their baleen.

Humpback whales eat krill, mackerel, sand lance, capelin, herring, pollock, smelt, cod, sardines, salmon, and anchovies. These whales are lunge-feeders but use several different techniques to concentrate their food before lunging.
Antarctic minke whales feed mainly on krill (Euphausia superba). Euphausia superba comprises 100% of stomach contents of minke whales caught at the ice edge and 94% (by weight) of the stomach contents of minke whales in the offshore zone.
They eat 6-7 tons of krill, a small, shrimp-like crustacean, per day, by gulp-feeding.
Freeze-dried shrimp and krill are a great treat for map turtles.
Interestingly, hatchlings and the young of several species of map turtles feed on more plant matter than adults.
Diet: These whales feed on krill (shrimplike crustacean), schools of small fish such as herring, and plankton. Like other baleen whales, the humpback obtains its food by straining it from water gulped into its mouth.
Magellanic penguins eat small fish, crustaceans, krill, and squid, and can swim at speeds of up to 15 miles per hour when pursuing prey.
A humpback whale's diet is made up of krill (small shrimp-like organisms), plankton (tiny organisms that float in the water), and small fish. Humpbacks feed by swallowing a mouthful of water containing its prey.
Humpback whales in the Southern Ocean feed mainly on the Antarctic krill. The humpback whale feeds in colder waters during spring, summer and autumn, then migrates to winter ranges in tropical seas, where it calves and breeds.
They feed on squid, fish and krill by either scavenging, surface seizing or diving. Albatrosses are colonial, nesting for the most part on remote oceanic islands.
Whereas baleen whales filter tiny prey (such as copepods and krill) en masse from the water, toothed whales capture and feed on large individual prey. The diet of toothed whales varies among the different groups.
Calves weigh between 1-2 tons, are 4-5 meters long and feed on their mother's milk until they can eat krill and small fish on their own.
The macaroni penguin feeds mainly on krill (shrimp-like crustaceans), although in some areas fish become an increasingly important food source as the breeding season progresses (5).

A large blue whale would need about 4,000 kg of krill perday. The much smaller minke whale would need about 71 kg per day. A blue whale can take up to 1,000 kg of krill in one feeding session. However, most whales do not feed the whole year.
Humpback whales migrate seasonally and feed on krill and small schooling fishes. Humpbacks catch the small fish be herding them into "bubble nets," which the whales create by swimming in a circle under the water's surface and releasing air bubbles.
Most penguins feed on krill, fish, squid and other forms of sea life caught while swimming underwater. Penguins spend a quarter of their life on land and three quarters in the oceans.
The speed at which small fish (which along with krill are the auk's principal food items) can swim doubles as the temperature increases from 5°C to 15°C, with no corresponding increase in speed for the bird.
Small fish, krill, shrimp, marine worms, and isopods are plucked from the water's surface or captured in a plunge dive. Near nesting sites, insects may be caught in flight.
