An international research team, along with Senckenberg scientist Dr. Ralf Britz & ECN PI Benjamin Judkewitz, have studied Danionella cerebrum, a small species of fish with a length of no more than 12 millimeters. Despite its diminutive size, the fish can produce sounds close to its body of over 140 decibels – comparable to a jet engine during take-off in 100 meter distance. In their study, published in the scientific journal “PNAS,” the researchers show that the tiny, translucent fish possess a special sound-generating apparatus.
