From dipoles to dinner: how efficient are sharks at navigating a prey's electric field?

Many animals rely on simple physical cues to perform complex behavioural tasks. For instance, sharks use electroreception to detect the weak electric fields produced by hidden prey. In this talk, I will explore how the observed simple geometric rule, maintaining a constant angle between the shark body axis and the local electric field, can generative effective prey approach trajectories. I will discuss how this rule arises naturally from the physics of electric fields, why it provides a robust strategy for hunting underwater, and what it may be reveal about the physical principles underlying animal navigation and predation.
