Abstract
Quantifying the energy requirements of animals in nature is critical for understanding physiological,
behavioural, and ecosystem ecology; however, for difficult-to-study species such as large sharks, prey intake
rates are largely unknown. 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.
