Cephalopods in the diets of Emperor and Adelie penguins in Adelie Land, Antarctica
Cephalopod remains were collected from all of 12 dead Emperor penguin chicks [Aptenodytes forsteri (Gray)], from 76% of 29 living adult Emperor penguins, and from 18% of 105 living adult Adelie penguins [Pygoscelis adeliae (Hombron & Jacquinot)] from Adelie Land, Antarctica, in 1982. Of the seve...
