But sharks, rays, skates and sawfish — members of a group called Elasmobranchii — are masters of detecting electric signals. It’s one of their defining features. Elasmobranchs have specialized organs called Ampullae of Lorenzini.

Electroreception. Most fish possess electroreceptors, which allow them to detect and locate conspecifics, predators and prey; Many Elasmobranchs can sense electrical impulses of other animals but not generate their own special fields as they possess sensory organs called the Ampullae of Lorenzini;

WebbFeeding habits vary with foraging methods and dentition. Sharks with teeth adapted to shearing and sawing are aided in biting by body motions including a rotation of the body, twisting movement of the head and body, or rapid vibration of the head. In coming to position, the shark protrudes its jaws, erecting and locking the teeth in position. WebbThe sensory organs of electroreception are the ampullae of Lorenzini, gel-filled canals on the heads of elasmobranchs (Kalmijn 1971). The gel is conductive, with resistance approximately equivalent to that of seawater (Kalmijn 1974).

WebbThe lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water.
