Recent scientific exploration has unearthed that a minuscule fish, among the tiniest on the planet, has the ability to produce sounds surpassing 140 decibels, analogous to the intensity of a jackhammer.
The Danionella cerebrum, a fish that boasts transparency and measures merely 12mm in length, possesses the tiniest brain recorded in any vertebrate to date.
The existence of the sound produced by this species was initially discerned by researchers in Berlin, Germany, as noises were detectable even when they ambulated near the aquariums housing the fish.
To investigate the phenomenon, the scientific team employed high-speed videography to scrutinize the fish within their tank.

Lead author of the study, Verity Cook, shared with New Scientist that “The fish are so loud that, even when just walking past their tanks, you can hear audible pulsing sounds.”
These sounds are believed to be generated by the act of the fish drawing one of its ribs towards its swim bladder to create a “drumming sound”.

This acoustic phenomenon appears to be exclusive to the male Danionella cerebrum. The objective behind their sound production is not completely understood, yet Cook surmises it could play a role in their communication or facilitate locating one another in environments where visibility is poor.
“The fact that it’s only males that make sound suggests that it’s to do with aggressive behaviour towards other males or mating behaviour with females,” she elaborated.
Insights from this study have been documented in the journal, Proceedings of the National Academy of Sciences.

FAQs About the Sound-Producing Danionella cerebrum
- How loud are the sounds produced by the Danionella cerebrum?
The sounds can reach over 140 decibels, which is on par with a pneumatic drill. - Can these sounds be heard outside the water?
Yes, researchers noted that the sounds are audible even when passing by the fish tanks. - What is the purpose of these loud sounds?
While the precise reason for these sounds is unknown, it is speculated to be related to communication, mating behavior, or territorial disputes amongst males. - Are both male and female Danionella cerebrum capable of making these sounds?
No, only male fish have been observed to produce these sounds.
Conclusion
The discovery of the Danionella cerebrum’s capability to emit such loud sounds is a surprising and illuminating addition to our understanding of aquatic life. While the reasons behind these vocalizations remain somewhat mysterious, the implications are significant in terms of communication and behavior among the tiniest of vertebrates. Continued research into such nuanced aspects of marine biology not only captivates our curiosity but also deepens our knowledge of the complexities within our planet’s ecosystems.
