Ecology
P. glacialis is known to feed on many crustaceans, fish, lanternfish antarctic krill, antarctic silverfish, and has been known to practice cannibalism.[2] Animals known to routinely feed on Glacial Squid (excluding cannibalism) include Antarctic Petrel, Light-mantled Sooty Albatross, Ross Seal, Southern Elephant Seal, Weddell Seal, Patagonian Toothfish, Wandering Albatross, Grey-headed Albatross, and the Emperor Penguin.[3]
