Sharks electroreception organ is called
WebbELECTRORECEPTION (ampullae of Lorenzini) Sharks have a complex electro-sensory system. Enabled by receptors covering the head and snout area. These receptors sit in jelly-filled sensory organs called the ampullae of Lorenzini. These tiny pores are extremely sensitive and can detect even the faintest of electrical fields. WebbEye of a big eyed sixgill shark . Electroreception. Most fish possess electroreceptors, which allow them to detect and locate conspecifics, predators and prey; Many Elasmobranchs can sense electrical impulses of other animals but not generate their own special fields as they possess sensory organs called the Ampullae of Lorenzini;

WebbFeeding habits vary with foraging methods and dentition. Sharks with teeth adapted to shearing and sawing are aided in biting by body motions including a rotation of the body, twisting movement of the head and body, or rapid vibration of the head. In coming to position, the shark protrudes its jaws, erecting and locking the teeth in position. 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 evolved from the mechanosensory lateral line organs of early vertebrates. Most bony fi…
