Webb17 apr. 2024 · Sharks and other ocean predators, including skates and rays, sense those electric fields. They do it using organs known as ampullae (AM-puh-lay) of Lorenzini. Scientists call such tissues electroreceptors because they detect electric fields. The ampullae look like a line of small holes, or pores, near the mouth on a shark’s snout. Webb26 mars 2024 · Sharks with ampullae of Lorenzini have an advantage when it comes to hunting, as they are able to detect even the most minute electrical signals, such as the …

Webb19 dec. 2016 · Mechanical disturbances picked up by the sensory cells of the lateral line system include those created by moving water, and by sound, vibration, and pressure changes. The Ampullae of Lorenzini detect electrical pulses in the water, and may also help sharks and rays navigate.

Webb16 mars 2024 · Abstract. Elasmobranch fishes, including sharks, rays, and skates, use specialized electrosensory organs called ampullae of Lorenzini to detect extremely small changes in environmental electric fields. Electrosensory cells within these ampullae can discriminate and respond to minute changes in environmental voltage gradients through … Webb13 maj 2016 · In 1678, Stefano Lorenzini first described a network of organs of unknown function in the torpedo ray-the ampullae of Lorenzini (AoL). ... The role of the AoL remained a mystery for almost 300 years until research demonstrated that skates, sharks, and rays detect very weak electric fields produced by a potential prey.
