Isotopic composition of potential white shark prey from different regions of the NEP.

‘ID’ is the number used to identify this species on Figure 2. For species with values based on collagen, both the reported values and values corrected to reflect muscle are reported respectively. ‘Lipids’ indicates if and how lipids were accounted for in the study (E = extracted, C = mathematically corrected, N: not accounted for), ‘Region’ denotes which focal area the prey are from and ‘N’ is sample size.*156 squid used in estimating nitrogen, 14 in carbon.
