The emperor penguin's diet consists mainly of fish, crustaceans and cephalopods, although its composition varies from population to population. Fish are usually the most important food source, and the [[Antarctic silverfish]] makes up the bulk of the bird's diet. Other prey commonly recorded include other fish of the family Nototheniidae, the [[glacial squid]], and the hooked squid species ''Kondakovia longimana'', as well as [[Antarctic krill]]. The emperor penguin searches for prey in the open water of the [[Southern Ocean]], in either ice-free areas of open water or tidal cracks in [[pack ice]]. One of its feeding strategies is to dive to around 50 m (160 ft), where it can easily spot sympagic fish like the [[bald notothen]] swimming against the bottom surface of the sea-ice; it swims up to the bottom of the ice and catches the fish. It then dives again and repeats the sequence about half a dozen times before surfacing to breathe. | The emperor penguin's diet consists mainly of fish, crustaceans and cephalopods, although its composition varies from population to population.
