These receptors are concentrated on the heads of sharks and can detect the minute electrical potentials generated by the muscle contractions of prey. Great White Sharks are known to react to charges of one millionth of a volt in water. The electroreceptors (known as ampullae of Lorenzini) are jelly-filled tubes that open on the surface of The ampullae de Lorenzini compose part of sharks' lateral line. The lateral line is a sensory organ in many fish and amphibians that stretches down their sides from gills to tail. The long, hollow tube opens out into the skin at perforated scales. This system allows sharks to sense water displacement, pressure and direction.

Ampullae of Lorenzini are a network of electroreceptors, sensory organs that detect electric fields in water, found in chondrichthyes (sharks, rays, and chimaeras). The ampullae are a series of symmetrical pores, concentrated around the snout and nose, connected by gel-filled canals.

Home > Ampullae of lorenzini Definition Ampullae of lorenzini Definition Special sensory organs that help sharks and rays to detect electric fields in the water. Used to locate prey. Ampullae of Lorenzini are a network of electroreceptors, sensory organs that detect electric fields in water, found in chondrichthyes (sharks, rays, and chimaeras). The ampullae are a series of symmetrical pores, concentrated around the snout and nose, connected by gel-filled canals. The Ampullae of Lorenzini are small clusters of jelly filled pockets that lead to jelly lined canals ending in small open pores located all over the heads of sharks.

Although humans build devices that detect electric fields, we do not feel the presence of weak fields around us. Sharks not only sense these fields but also rely on them to locate prey and, perhaps, navigate through the ocean. Ampullae of Lorenzini Named after the 17th-century anatomist who first described them, these skin pores stipple the head and body of sharks.
