abstract
Euphausiid crustaceans were found in samples of stomach contents taken from rockhopper penguins Eudyptes chrysocome and macaroni penguins E. chrysolophus at Marion Island and from rockhopper penguins at Gough Island. Thysanocssa spp. were the principal prey recorded at both localities. Euphausia sp. were only found in macaroni penguin stomach samples. The results confirm the importance of euphausiid crustaceans in the diet of Eudyptes penguins at sub-Antarctic localities.
