Shark ampullae of lorenzini location
Webb1 aug. 2015 · The lateral line sense organs of sharks include ampullae of Lorenzini and neuromasts. Each of these two classes of receptors is highly specialized and therefore can be expected to biologically respond to one specific modality of stimulus of minimal threshold intensity. WebbThe fields are detected by sensory organs known as ampullae of Lorenzini, which in some tests have been shown to function at distances of up to a few feet. As in the lateral line system, the electroreceptor sensory cells connect with the outside seawater through gel-filled canals which open at pores on the skin.
