Mechanics, hydrodynamics and energetics of blue whale lunge feeding: efficiency dependence on krill density

Goldbogen, J. A.; Calambokidis, J.; Oleson, E.; Potvin, J.; Pyenson, Nicholas D.; Schorr, G.; Shadwick, R. E. (2011)

Lunge feeding by rorqual whales (Balaenopteridae) is associated with a high energetic cost that decreases diving capacity, thereby limiting access to dense prey patches at depth. Despite this cost, rorquals exhibit high ...
Why whales are big but not bigger: Physiological drivers and ecological limits in the age of ocean giants

Goldbogen, J. A.; Cade, D. E.; Wisniewska, D. M.; Potvin, J.; Segre, P. S.; Savoca, M. S.; Hazen, E. L.; Czapanskiy, M. F.; Kahane-Rapport, S. R.; DeRuiter, S. L.; Gero, S.; Tonnesen, P.; Gough, W. T.; Hanson, M. B.; Holt, M. M.; Jensen, F. H.; Simon, M.; Stimpert, A. K.; Arranz, P.; Johnston, D. W.; Nowacek, D. P.; Parks, S. E.; Visser, F.; Friedlaender, A. S.; Tyack, P. L.; Madsen, P. T.; Pyenson, N. D. (2019)

The largest animals are marine filter feeders, but the underlying mechanism of their large size remains unexplained. We measured feeding performance and prey quality to demonstrate how whale gigantism is driven by the ...
