Antarctic silverfish: life strategies of a key species in the high‐Antarctic ecosystem
Abstract Among the endemic notothenioid fish of Antarctica, the Antarctic silverfish ( Pleuragramma antarcticum ) is the only species in which all developmental stages live throughout the water column. It is widely distributed in the shelf waters around the continent, inhabiting both open waters and...
