  • A fish about one centimeter in size can produce noise comparable to that of a jet engine when an airplane takes off.
  • The transparent fish of the species Danionella cerebrum have a sound-producing apparatus that can reach more than 140 decibels.

The fish probably use the sounds to communicate with other members of their species in cloudy waters, according to the Senckenberg Society for Natural Research reported. An international research team studied the fish native to Myanmar’s shallow and murky waters using a combination of high-speed video, micro-computed tomography, gene expression analysis and mathematical methods.

It was shown that the males of the Danionella species have a unique sound-producing apparatus that includes a drum cartilage, a special rib and a fatigue-resistant muscle.

Other animals are loud too

The 140 decibels generated are comparable to the volume that a person perceives a hundred meters away when an airplane takes off. Other animals can also be loud. The noise that the pistol crab produces with its scissors is up to 250 decibels loud.

The flightless kakapo’s mating calls reach 130 decibels, and elephants reach volumes of up to 125 decibels with their trunks. The male northern boatswain fish also attracts its females with an audible vibrato of around 100 hertz and 130 decibels. The study appeared in the journal PNAS.

This device accelerates the drumming cartilage with considerable force and “shoots it at the swim bladder to generate a fast, loud impulse,” explained Senckenberg researcher Ralf Britz. When strung together, these impulses produce calls.
