The health of dolphin populations worldwide depends on sustained access to robust food sources.A new report by UC Santa Barbara researchers and colleagues at UC San Diego and the National Oceanic and Atmospheric Administration looks at three different dolphin species, studying what they eat and how they divide ocean resources and space — important information for conservation and management. The team's findings appear in the journal PLOS ONE."We used the principle of 'you are what you eat' to unlock some of the secrets of dolphin diet," said lead author Hillary Young, an assistant professor in UCSB's Department of Ecology, Evolution, and Marine Biology (EEMB). "All of the foods that we or any animal eat are incorporated after digestion into body tissues. Most Americans, for example, chemically look like walking corn cobs because the foods we eat contain so much corn syrup."
