Antarctic krill play a vital role in the Antarctic food web, providing a major part of the diet of larger species such as whales, seals, penguins and fish. During deep dives, an Emperor penguin's heart rate slows to a rate that is 15% lower than its resting heart; this helps the penguin conserve energy. Processes of moult, growth, and reproduction are locally and seasonally adjusted. | Women's is more or less transparent, with a pair of big black eyes. Together with the tight fit of the upper and lower jaw, a bony protuberance near the back of the mouth completes a near-perfect sieve within which krill are trapped. They have numerous adaptations which have helped them secure their place as one of the world's species with the most biomass, including massive compound eyes, a "feeding basket" for filter feeding, a muscular telson (tail) that can be used to rapidly "lobster" away from predators, bioluminesence (the utility of which is not fully understood), swarming behavior, the ability to shrink in size from one molt to … Antarctic Animals List Molecular adaptation in Antarctic bacteria: P. haloplanktis TAC125.
