ICES Journal of Marine Science, 55: 467–481. 1998 Diet composition and trophic levels of marine mammals
Standardized diet compositions were derived for 97 species of marine mammals from published accounts of stomach contents as well as from morphological, behavioural and other information. Diet was apportioned among eight categories of prey types (benthic invertebrates, large zooplankton, small squids...
