WitrynaIn 1678, while doing dissections of sharks, the Italian physician Stefano Lorenzini discovered organs on their heads now called ampullae of Lorenzini. He published his findings in Osservazioni intorno alle torpedini. The electroreceptive function of these organs was established by R. W. Murray in 1960.

These organs, the Ampullae of Lorenzini (AoL), are widely distributed and comprise a series of gel-ﬁ lled canals emanating from pores in the skin (Figure 1A). The canals extend into bulbous structures called alveoli that contain sensory cells capable of detecting subtle changes

WitrynaELECTRORECEPTION (ampullae of Lorenzini) Sharks have a complex electro-sensory system. Enabled by receptors covering the head and snout area. These receptors sit in jelly-filled sensory organs called the ampullae of Lorenzini. These tiny pores are extremely sensitive and can detect even the faintest of electrical fields.

WitrynaThe electroreceptors (known as ampullae of Lorenzini) are jelly-filled tubes that open on the surface of sharks’ skin. …. Electroreceptors are most often used to capture prey, by the detection of electrical fields generated by the prey. For example, this allows sharks to find prey hidden in the sand.
