Dessa organ  The ampullae of Lorenzini are special sensing organs called electroreceptors, forming a network of jelly-filled pores.They are mostly discussed as being found in cartilaginous fish (sharks, rays, and chimaeras); however, they are also reported to be found in basal actinopterygians such as reedfish and sturgeon. 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.

These receptors are concentrated on the heads of sharks and can detect the minute electrical potentials generated by the muscle contractions of prey. The electroreception ability is enabled by the Ampullae of Lorenzini. These are modified sensory organs situated on the snout or nose of the shark and can number from a few hundred (for the more placid sharks) to well over 1000 for active hunters and killers.
