electroreception

Ampullae of Lorenzini are a network of electroreceptors, sensory organs that detect electric fields in water, found in chondrichthyes (sharks, rays, and chimaeras).  The ampullae are a series of symmetrical pores, concentrated around the snout and nose, connected by gel-filled canals.  They can conduct electrical impulses so small, that chondrichthyes are likely to be more sensitive … [Read more…]
