Diving physiology

Diving physiology vs behaviour

How does the physiology of marine mammals affect their diving abilities and foraging strategies?

Marine mammals catch their prey at depth, under challenging physical conditions. While they excel at diving, they are ultimately limited by their physiology. We explore the physiology and energetics of diving mammals, and test how their behaviour and foraging costs are affected by changing prey fields.
