Abstract Epidermal skin samples from eastern North Atlantic killer whales, Orcinus orca , were analyzed for carbon and nitrogen stable isotope ratios. From those, comparisons within a data set of 17 samples collected from Tysfjord, Norway, in November suggested that diet is relatively specialized du...
