2021-04-12 · Electric shark repellent technology was first proposed in the 1990s, based on the special short-range electric receptor system sharks have called the ampullae of Lorenzini. Located on their snout 1. The ampullae of Lorenzini are sensitive to weak electrical stimuli which presumably cause currents to flow along the jelly-filled tubes of the sense organ.

These disturbances can be detected by sharks and rays by electroreceptors, specialized pores on the skin around their head and on the underside of their snout. These are called Ampullae of Lorenzini. A single shark can have thousands of these on their snout, with the hammerhead shark known to have over 3000.

Mackerel Sharks use ampullae of Lorenzini, a sensory organ that detects electromagnetic fields in other animals.

This system allows sharks to sense water displacement, pressure and direction. 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.
