The secret of the fish as loud as a plane taking off has been revealed. It has an ad hoc apparatus to communicate in murky waters.
Danionella cerebrum can produce sounds of over 140 decibels at a distance of 10-12 millimeters. This is comparable to the noise that a human can perceive 100 meters away from a plane take off. The apparatus is made up of a cartilage that vibrates like a drum, a specialized rib and a muscle resistant to fatigue.
