Fish can sense sound through their lateral lines and their otoliths (ears). Some fishes, such as some species of carp and herring, hear through their swim bladders, which function rather like a hearing aid. [9] Because of their electrosensitivity, sharks avoid certain rare-earth elements, such as lanthanide, which have magnetic properties. Experiments are ongoing to test whether certain metals or strong magnets can induce sufficient avoidance that they may be used for reducing bycatch in certain fishing gears (Richards et al. 2018).

Hearing is an important sensory system for most species of fish. For example, in the family Batrachoididae, males use their swim bladders to make advertisement calls which females use to localize males. Hearing threshold and the ability to localize sound sources are reduced underwater, in which the speed of sound is faster than in air. Underwater hearing is by bone conduction, and localization of sound appears to depend on differences in amplitude detected by bone conduction. [7] As such, aquatic animals such as fish have a more specialized hearing apparatus that is effective underwater.

Most fish possess highly developed sense organs. Nearly all daylight fish have color vision that is at least as good as a human's (see vision in fish). Many fish also have chemoreceptors that are responsible for extraordinary senses of taste and smell. 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]Also like humans, the retina of the fish’s eye is made up of photosensitive rods and cones. The rods detect only the presence or absence of light, and the cones detect color (Douglas and Djamgoz 1990). Most bony fish can detect color (Marshall et al. 2017). Most sharks, however, have only rods, and therefore they distinguish contrast, not color. In most bony fish, rods for low-light vision are much more common than cones, which are better for bright-light vision. As a general rule, the deeper a fish lives the fewer cones it has.

But fish use sense for more than just finding food. Fish can rely on one or more sensory cues and different sensory mechanisms to gain information about their environment and guide their behavior. Senses are engaged whether the fish is moving toward a sound, away from a threat, or following a scent of food or pheromones. For example, young glass eels ( Anguilla spp.) return to estuaries and detect currents using their magnetic compass to memorize magnetic direction of tidal flows (Cresci et al. 2019). As you learn more about the sensory capabilities of fish, you will be better able to understand their behavior. 3.2 Characteristics of the Water Shape Sensory CapabilitiesKasumyan, A. O. 2019.
