WebFeb 13, 2024 · The electroreceptors (known as ampullae of Lorenzini) are jelly-filled tubes that open on the surface of sharks’ skin. Inside, each tube ends in a bulb known as the … WebNear the barbels are the ampullae of Lorenzini, which are specialized organs for detecting electrical fields. Two dorsal fins are present, with the second being slightly smaller than the first. They lack an anal fin. Five gill slits are present on each side of the head, while most sawsharks have gills on the bottom of the head.

These organs are found by the stingray’s mouth and sense the natural electrical charges that other animals emit. Many ray species also have jaw teeth which they use to crush mollusks such as mussels, clams, and oysters.
WebDec 2, 2024 · To detect electric fields, animals with electroreception have organs called “ampullae of Lorenzini,” named for the scientist who thought their bulbous structure resembled tiny flasks called ampules. External bioelectric fields cause negative electric charges to accumulate at the surfaces of special skin pores. WebThe ampullae of Lorenzini are special sensing organs, forming a network of jelly-filled canals found on elasmobranchs (sharks and rays) and Chimaera. Each ampulla consists of a jelly …
Ampullae of Lorenzini (singular Ampulla) are electroreceptors, sense organs able to detect electric fields.
