Without the existence of krill many animals living in Antarctic waters would not survive. Antarctic krill (Euphausia superba) are the main diet of whales, penguins and seals and form some of the highest concentrations of animal biomass in the world’s oceans – with over an estimated 150 million tonnes. It seems that some krill swarms may be made up of entirely of juveniles, while other swarms may consist of all females or all males. The postcanine teeth are finely divided with multiple cusps.
