1. From source #1 - Ichthyology at the Florida Museum of Natural History education webpage http://www.flmnh.ufl.edu/fish/education/questions/Biology.html: "Sharks have many keen senses that are mostly geared towards helping them locate prey. Depending on the species or the environment certain senses are more or less important to them for locating their targeted prey, which is most often fish. Sharks use the senses of smell (chemoreception), vision, hearing, the lateral line system, and electroreception (ampullae of Lorenzini) for capturing prey. The lateral line system, which all fishes possess, allows them to detect waves of pressure or mechanical disturbances in the water. The ampullae of Lorenzini are receptors that can detect weak electric fields. This sense is unique to sharks and their relatives. Sharks primarily use this sense to locate cryptic prey which can not be detected by their other senses, such as stingrays buried in sand. The stingray, like all living animals, emit weak electric fields produced by muscular contractions in the body. Sharks have the extra predatory advantage of being able to detect those fields at close range."

The lateral line system, which all fishes have, allows them to perceive pressure waves or physical disturbances in the water. The ampullae of Lorenzini are receptors that can perceive weak electric fields. This sense is only used in sharks and their relatives. [1]

The lateral line system, which all fishes possess, allows them to detect waves of pressure or mechanical disturbances in the water. The ampullae of Lorenzini are receptors that can detect weak electric fields. This sense is unique to sharks and their relatives. Student’s text: Sharks have many sensory organs which they use to catch their prey: eyes for sight, nostrils for smell, ears for hearing, lateral lines for perceiving pressure waves and other physical disturbances, and ampullae of Lorenzini for perceiving weak electrical fields. All fish have the lateral line system, but only sharks and their relatives have the amullae of Lorenzini. [1]
