WebDec 19, 2016 · The ampullae of Lorenzini are small vesicles and pores that form part of an extensive subcutaneous sensory network system. These vesicles and pores are found around the head of the shark and are visible to the naked eye. They appear as dark spots in the photo of a porbeagle shark head below. The ampullae detect weak magnetic fields … WebAbout. Hammerhead sharks are one of the most recognizable sharks in the sea! No one has a head quite like theirs, which is where they got their name (no surprise). Hammerhead sharks have very wide-set eyes, which gives them a better field of vision than other sharks.

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 … See more 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 … See more Ampullae of Lorenzini are physically associated with and evolved from the mechanosensory lateral line organs of early vertebrates. Passive electroreception using ampullae is an See more The ampullae detect electric fields in the water, or more precisely the potential difference between the voltage at the skin pore and the voltage … See more The mucus-like substance inside the tubes may perhaps transduce temperature changes into an electrical signal that the animal may use to … See more Each ampulla is a bundle of sensory cells containing multiple nerve fibres in a sensory bulb (the endampulle) in a collagen sheath, … See more Ampullae of Lorenzini also contribute to the ability to receive geomagnetic information.
