Although they have ears, many fish may not hear very well. Most fish have sensitive receptors that form the lateral line system, which detects gentle currents and vibrations, and senses the motion of nearby fish and prey. [1] Sharks can sense frequencies in the range of 25 to 50 Hz through their lateral line. [2]
Ampullae of Lorenzini (sg.: 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 , [ 1 ] sturgeon , [ 2 ] and lungfish . [ 1 ]

Great white sharks have six senses. This great white shark was observed by 11 divers off the Breakers Reef in Palm Beach in July 2020. It was estimated to be about 20 feet in length.
The five senses that blue sharks share with other members of the Carcharhinidae family is vision, hearing, lateral line, chemoreception, and electroreception. These senses allow them to perceive and react to a variety of biotic and/or abiotic stimuli in their immediate environment and across a different range of spatial scales. [15]
In active electrolocation, fish generate a weak electric field and sense the different distortions of that field created by objects that conduct or resist electricity. Active electrolocation is practised by two groups of weakly electric fish , the Gymnotiformes (knifefishes) and the Mormyridae (elephantfishes), and by Gymnarchus niloticus , the ...
Bait 3D. Bait, a 2012 Australian-Singaporean film, perhaps sets up the most unique of premises in a movie involving people-hungry sharks.The movie follows a bunch of grocery store workers who are ...
Other senses which can also provide data about location or distant objects include hearing and echolocation, electroreception, magnetoception and chemoreception (smell and taste). For example, catfish have chemoreceptors across their entire bodies, which means they "taste" anything they touch and "smell" any chemicals in the water.
