How much energy does a dolphin use to swim?

From foraging for prey to evading predators and ship strikes, a dolphin's survival depends on speedy swimming, but burning all that energy can delete the metabolic reserves vital for growth, health and reproduction. A new study provides scientists with a new metric for estimating how much energy wild dolphins expend on swimming -- information that is essential for answering fundamental questions about their physiology and ecology, and for understanding the impacts of human disturbances on them.
