The authors acknowledge the Natural Environment Research Council for support with this work (grant NER/A/S/2003/00616). Simple scaling arguments suggest that, among air-breathing divers, dive duration should scale approximately with mass to the one-third power. Recent phylogenetic analyses appear to...
