"Uncovering the Astonishing Noise-Making Abilities of a Newly Discovered Tiny Fish"

A new study reveals that the Danionella cerebrum, a tiny fish discovered three years ago, can produce sounds as loud as 140 decibels, comparable to the noise of an airplane during take-off. The fish possesses a unique sound-generating organ and uses a specialized apparatus to create rapid, loud pulses for communication in visually restrictive environments, challenging the notion that fish are generally quiet animals.

"Tiny Fish Shocks Scientists with Deafening Sound Comparable to Gunshot"

Scientists have discovered that the male Danionella cerebrum, one of the world’s smallest fish, can produce sounds as loud as a gunshot, exceeding 140 decibels, using a unique sound production system involving a drumming cartilage, specialised rib, and fatigue-resistant muscle. This mechanism, driven by a special muscle moving a rib into a piece of cartilage next to the swim bladder, allows the fish to generate rapid, loud pulses. The reason for the loud sounds is not yet established, but it is suggested that it could help the fish navigate murky waters or serve as an aggressive tactic used by males to warn off competition.
