International audience 1. Optimal diving models have been developed to investigate how air-breathing predatorsshould adjust their diving behaviour to optimize their foraging efficiency. Using time-depthrecorders and 3D accelerometers, we addressed this question on six free-ranging Southern ElephantS...
