A small shrimplike planktonic crustacean of the open seas. It is eaten by a number of larger animals, notably the baleen whales.
Many species in the class Malacostraca, especially Meganyctiphanes norvegica
‘But in years of no sea ice, what krill the researchers found were significantly larger.’
‘For example, during its primary feeding season the blue whale consumes upwards of 40 million krill each day in order to secure adequate nutrition.’
‘The underside of the ice acts like an upside-down coral reef, providing young krill both food and shelter.’
‘But when the humpbacks are rounding up krill - small, shrimpy crustaceans - the net may be as small as five feet across.’
‘Gómez-Gutiérrez said that he does not know how the parasites get inside the krill, but that once inside they eat all the krill's organs.’
‘The krill, in turn, are the Adelie penguins' primary food.’
‘Parliament's resolution said that seals and whales eat at least 5.5 million tons of fish and krill a year, double the tonnage caught by fishermen.’
‘Opportunistic feeders, they surface-feed, gulping small schooling fish, pelagic crabs, and swarms of krill when encountered.’
‘His work has focused on the whales' principal food, the inch-long, shrimplike marine animals known as krill.’
‘The other birds forage at sea for fish, squid, and krill (small, shrimplike crustaceans).’
‘In coastal areas during the non-breeding season, fish, krill and other marine creatures make up a large portion of their diet.’
‘If, however, they make the journey safely to the West coast of Greenland, they'll soon thrive on a rich diet of herring, eel and the shrimp-like krill.’
‘The acid is found in organisms, including sardines and krill that eat the algae and that are in turn eaten by the squid.’
‘Female krill were later analyzed for ovarian physiological maturity.’
‘Masses of the parasite grow inside the krill, eat its organs, divide, and then burst out of their host's dead body in search of new victims.’
‘The baleen whales feed primarily on plankton and krill.’
‘Depending on the species, whales are either major consumers of plankton or krill or they are major predators, feeding on seals, fish, and penguins.’
