Mullet, or grey mullet, are a family of ray-finned fish found in coastal temperate and tropical waters worldwide, and some species are found in freshwater. They are distinguished by their two separate dorsal fins, small triangular mouths, and the absence of a lateral line organ. While it is unclear whether mullet fish are sensitive to sound, fish, in general, do have a sense of hearing. They respond to sound and can detect vibrations in water. Some fish species have better hearing abilities due to anatomical differences.

What You'll Learn
Mullet fish are sensitive to sound and vibrations
Mullet fish, also known as "jumping mullet" or "grey mullet", are a type of ray-finned fish found in coastal temperate and tropical waters worldwide, as well as in some freshwater environments. They are a popular target for anglers due to their abundance in coastal areas and estuaries, strong and agile swimming abilities, and their reputation for putting up a good fight when caught on a fishing line.
Mullet fish are indeed sensitive to sound and vibrations. While sound doesn't travel well between air and water, sounds that occur underwater are loud and fast-travelling. Fish, including mullet, possess highly developed sense organs that enable them to detect sounds and vibrations. They have sensitive receptors that form the lateral line system, which helps them detect gentle currents and vibrations, as well as sense the motion of nearby fish and prey. This system is composed of cilia, or nerve hairs, that translate acoustically induced particle motion and pressure gradients into the sensory system of the fish.
The ability to sense vibrations in the water is particularly useful for mullet fish when hunting for prey. They can detect changes in water vibrations to locate and capture their prey. Additionally, mullet fish are known to be easily spooked, which can impact their behaviour and deter them from taking bait.
It is worth noting that the sensitivity to sound and vibrations may vary among different species of mullet fish, as they can have varying sizes and habitats. Smaller fish, for instance, may be more easily scared by loud noises, while larger fish may exhibit indifference or react by attacking.
While mullet fish are sensitive to sound and vibrations, the specific mechanisms and adaptations related to hearing and sound perception may differ from those of terrestrial vertebrates. Fish have sonic muscles that vibrate their swim bladders to produce sound. The frequency range of audible sounds varies across species, and fish may prioritize velocity sensing over amplitude sensing in their auditory adaptations.

They are easily spooked by loud noises
Mullet fish are easily spooked by loud noises, and anglers take advantage of this fact. Fishermen use light monofilament lines, thin wire hooks, and small foam floats to avoid making too much noise and scaring the fish. Mullet fish are strong and fast swimmers, and they often jump out of the water to escape danger. This behaviour is so common that they are sometimes called "jumping mullet".
While sound doesn't travel well between air and water, and loud talking or screaming is barely noticeable to fish underwater, sound that occurs underwater is loud and travels fast. Most fish have highly developed sense organs. They have sensitive receptors that form the lateral line system, which detects gentle currents and vibrations and senses the motion of nearby fish and prey.
Goldfish, for example, are very sensitive to vibrations in the water. Tapping on the side of a goldfish tank or making a loud noise nearby will cause strong vibrations and startle the fish. Similarly, smaller fish may be scared by a loud noise, while larger fish may seem indifferent to the same. Smaller fish may feel the pressure of loud sounds and react by escaping, while larger fish may react to a loud sound as a potential threat and attack.
Fish make sounds as well. They have sonic muscles, which are the fastest contracting muscles known in vertebrates. These muscles move and vibrate the swim bladder, an air chamber in the abdomen of a fish. These rapid internal movements produce sound. The colder the water temperature, the slower the sonic muscles contract, which can lower the pitch of the sound.
Fish also use their senses to detect changes in the water’s vibrations to find prey. While betta fish do not have super hearing, they can hear your voice. They are different from cats and dogs in that they cannot recognize their names.

Smaller mullet fish may escape when scared
Mullet fish, also known as "jumping mullet" or "grey mullet", are a family of ray-finned fish found in coastal areas and estuaries. They are agile swimmers, found in both saltwater and freshwater habitats. They are a popular target for anglers due to their abundance and the strong fight they put up when caught on a line. They are strong, fast, and tend to leap out of the water to escape predators.
Fish are known to have highly developed sense organs. They possess sensitive receptors that form the lateral line system, which detects gentle currents, vibrations, and the motion of nearby fish and prey. This system is composed of cilia, or nerve hairs, that translate acoustically induced particle motion and pressure gradients into the sensory system of the fish. These cilia are similar to those found in the cochlea of terrestrial vertebrates.
Additionally, fish have gas-filled swim bladders that mediate buoyancy and also serve as pressure gradient sensors. The practicality and nature of these adaptations depend on various factors, such as whether the fish are gregarious or solitary, predators or prey, and their habitat. While the specific mechanisms may vary between species, all fish are believed to respond to sound in some capacity.
In conclusion, smaller mullet fish may be more sensitive to sound and are likely to escape when scared by loud noises. They possess sensory organs and adaptations that allow them to detect and respond to sound pressure and vibrations in their environment. Anglers targeting mullet fish should be mindful of this sensitivity and maintain quiet to avoid spooking the fish.

Larger mullet fish may react to loud sounds as a potential threat
While sound does not travel well between air and water, underwater sound travels faster than it does in air. Therefore, loud talking or screaming will be barely noticeable to fish underwater, and they won't be scared or spooked. However, fish do have a highly developed sense of vibration detection, which they use to find prey and detect the motion of nearby fish.
Mullet fish, also known as "jumping mullet" or "grey mullet", are a popular target for anglers due to their abundance in coastal areas and estuaries. They are agile swimmers and can be found in saltwater and freshwater habitats. They are strong, fast, and known for putting up a good fight when caught on a line. They often jump out of the water in an attempt to escape.
Mullet fish belong to the Mugilidae family, which includes about 80 species distributed worldwide. In the US, two of the most common species are the striped mullet (*Mugil cephalus*) and white mullet (*Mugil curema*). Striped mullet are prevalent along the Atlantic Coast, from Massachusetts to Florida, and throughout the Gulf of Mexico.
Fish respond to sound through their acoustical adaptations, which vary depending on the species. These adaptations are influenced by factors such as habitat, behaviour, and whether they are predators or prey. While fish do not have ears, they can "feel" sound pressure, similar to how deaf people can feel the vibrations of loud music.

Mullet fish have highly developed sense organs
Fish are known to respond to sound, and mullet fish, in particular, are known to be easily spooked. While sound doesn't travel well between air and water, noises that occur underwater are loud and fast-travelling. This means that loud talking or screaming will not be noticeable to the fish underwater, but they can still hear your voice.
The lateral line system is made up of cilia (nerve hairs) that serve as mechanoreceptors, translating acoustically induced particle motion and pressure gradients into the sensory system of the fish. This system allows fish to sense sound and the proximity of other moving bodies, which is how they are able to swim in tightly synchronised schools. The practicality of these adaptations depends on the habitat of the fish, whether they are gregarious or solitary, predators or prey, nocturnal or diurnal, shallow or deep water, etc.
Fish also have other sound perception organs, including bladders, which are used to mediate buoyancy and can also serve as pressure gradient sensors. They also have sonic muscles, which are the fastest-contracting muscles known in vertebrates, designed to move and vibrate the swim bladder. These rapid internal movements produce sound. The colder the water temperature, the slower the sonic muscles contract, which lowers the pitch of the sound.

Frequently asked questions
Mullet fish do not have a lateral line organ, which is used by some fish to detect sound. However, they do have other highly developed sense organs and sensitive receptors that detect gentle currents and vibrations. Therefore, while mullet fish may not be as sensitive to sound as other fish, they can still sense vibrations in the water.
Fish can hear extremely low frequencies, often no more than 800-1000 Hz. They are able to discriminate between sounds of different amplitudes and frequencies and between different calls.
Smaller fish may be scared by loud noises and react by escaping. However, since sound doesn't travel well between air and water, loud talking or screaming will be barely noticeable to fish underwater.
