The ampullae of Lorenzini (sing. ampulla) 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). They provide fish with an additional sense capable of detecting electric and magnetic fields as well as temperature gradients.
