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 ), from 76% of 29 living adult Emperor penguins, and from 18% of 105 living adult Adelie penguins (Pygoscelis adeliae ) from Adelie Land, Antarctica, in 1982. Of the seven species of squids represented...

Description
Summary:Cephalopod remains were collected from all of 12 dead Emperor penguin chicks (Aptenodytes forsteri ), from 76% of 29 living adult Emperor penguins, and from 18% of 105 living adult Adelie penguins (Pygoscelis adeliae ) from Adelie Land, Antarctica, in 1982. Of the seven species of squids represented by lower beaks. Psychroteuthis glacialis comprised 88% of the number in both Emperor chicks and Emperor adults and 100% in Adelie adults. Gonatus antarcticus and Kondakovia longimana contributed 18 and 14%, respectively, of the weight of squids in the diet of Emperor chicks and 27 and 21%, respectively, in the diet of Emperor adults.
