The variability in catfish sound signals differs due to a few factors: the mechanism by which the sound is produced, the function of the resulting sound, and physiological differences such as size, sex, and age. [61] To create a drumming sound, catfish use an indirect vibration mechanism using a swimbladder. In these fishes, sonic muscles ...
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. [8] Fish can sense sound through their lateral lines and their otoliths (ears).
Individuals within the group that produced sound avoided obstacles, whereas silent individuals crashed into obstacles frequently. Many fish have been associated with sound production for alarm, territorial, and courtship purposes, but sound probing of surroundings seems to be only be seen in hardhead catfish.
In many channel catfish, individuals favor one fin or another for stridulatory sound production (in the same way as humans are right-handed or left-handed). [26] The first ray of the channel catfish pectoral fin is a bilaterally symmetrical spinous structure that is minimally important for movement; however, it can be locked as a defensive ...
Synodontis make a sound that sounds like squeaking by rubbing their spines together. They do this when they have been frightened or when they become angry. [2] Synodontis may also squeak when they are taken out of the water. [1] These catfish are small- to medium-sized fish [4] with many species
Amphibians like frogs and toads can vocalise using vibrating tissues in airflow. For example, frogs use vocal sacs and an air-recycling system to make sound, while pipid frogs use laryngeal muscles to produce an implosion of air and create clicking noise. [7] Aquatic mammals such as seals and otters can produce sound using the larynx.
Weberian apparatus and air-bladder of a carp. The Weberian apparatus is an anatomical structure that connects the swim bladder to the auditory system in fishes belonging to the superorder Ostariophysi.
This increases the ability of sound detection. [7] The swim bladder can radiate the pressure of sound which help increase its sensitivity and expand its hearing. In some deep sea fishes like the Antimora, the swim bladder maybe also connected to the macula of saccule in order for the inner ear to receive a sensation from the sound pressure. [8]
