Description
Yannis Papastamatiou and co-authors ask how the cost of moving through water shapes where different hunters gather in the sea. Groups of predators from several species often meet to feed or rest. But each species differs in body shape, buoyancy, and length, so the same patch of ocean costs each of them a different amount of energy. The team calls this cost map the energy landscape.
A model of swimming shows how a shark's length and buoyancy change the saving it gets from riding rising currents, which let heavy sharks rest their muscles. Field evidence from a channel in French Polynesia shows shark species spacing themselves out in line with those savings. The team also shows how the landscape sets how long each species stays at a feeding patch before leaving.
