How Do Ampullae of Lorenzini Work?

electroreceptors
Fish use passive electroreception to supplement or replace their other senses when detecting prey and predators. In sharks, sensing an electric dipole alone is sufficient to cause them to try to eat it.

called ampullae of Lorenzini. These receptors are concentrated on the heads of sharks and can detect the minute electrical potentials generated by the muscle contractions of prey.

How does the ampullae of Lorenzini help sharks?

The ampullae of Lorenzini (Figures 3.15 and 3.37) are modified parts of the lateral line system (see later) and primarily sensitive to electrical fields (they can help a shark sense prey by detecting the electrical fields generated by activities of the prey).

What is the function of ampulla of Lorenzini?

The ampullae of Lorenzini allow sharks to sense electric and magnetic fields. This capability has resulted in unique displays of behaviors in both sharks and rays. The ability to detect these fields is dependent on head morphology, which can also shape behavior as a result.
