Here, we use metabolic rates derived from swimming speed estimates to suggest that feeding requirements of the world’s largest predatory fish, the white shark (Carcharodon carcharias), are several times higher than previously proposed. Further, our estimates of feeding frequency identify a clear benefit in seasonal selection of pinniped colonies - a white shark foraging strategy seen across much of their range.
