WebbLike its shark relatives, the stingray is outfitted with electrical sensors called ampullae of Lorenzini. Located. Unlock this story for free. WebbAmpullae of Lorenzini are a network of jelly-filled pores, which allow the shark to detect electrical fields when prey are distressed or injured and aids in their capture. Also, when fish and other organisms give off an electrical field when swimming, the whitetips use the ampullae of Lorenzini to pinpoint their location.

ampullae of Lorenzini Encyclopedia.com

Ampullae of Lorenzini (singular Ampulla) are electroreceptors, sense organs able to detect electric fields. They form a network of mucus-filled pores in the skin of cartilaginous fish (sharks, rays, and chimaeras) and of basal bony fishes such as reedfish, sturgeon, and lungfish. They are associated with and … Visa mer Ampullae were initially described by Marcello Malpighi and later given an exact description by the Italian physician and ichthyologist Stefano Lorenzini in 1679, though their function was unknown. Electrophysiological experiments … Visa mer Ampullae of Lorenzini are physically associated with and evolved from the mechanosensory lateral line organs of early vertebrates. … Visa mer The ampullae detect electric fields in the water, or more precisely the potential difference between the voltage at the skin pore and the voltage … Visa mer The mucus-like substance inside the tubes may perhaps transduce temperature changes into an electrical signal that the animal may use to … Visa mer Each ampulla is a bundle of sensory cells containing multiple nerve fibres in a sensory bulb (the endampulle) in a collagen sheath, … Visa mer Ampullae of Lorenzini also contribute to the ability to receive geomagnetic information. As magnetic and electrical fields are related, Visa mer • Knollenorgan – a non-homologous type of electroreceptor, found in mormyrid fishes Visa mer Webb10 okt. 2007 · Ampullae of Lorenzini [] are sense organs on the head of sharks [], rays [5, 12], and chimaeras [], containing a gel reported to have unique thermoelectric semiconductor properties [].(a) Visible as small pores around the oral surface of a skate (Raja erinacea) (arrow), the tubular organs, with an alveolus-shaped ending containing … Webbogy of sawfish combines an elongated, shark-like body with the pectoral disk of batoids and an elongated ros-trum that bears lateral teeth [Compagno, 1999a; Last and Stevens, 2009].
