A recent study revealed that a tiny fish, which was first discovered three years ago, produces loud sounds comparable to a pneumatic drill using a unique drumming method.
The Danionella cerebrum, known for its see-through body and exposed skull, is a type of fish that is commonly found in small streams throughout the Bago Yoma mountain range in Myanmar.
Because of its diminutive size, translucent appearance, and accessibility for examination at the microscopic level, the fish is increasingly recognized as a valuable model organism in the field of biomedical research.
Ever since the species was found in 2021, researchers have been puzzled by how this fish, which is smaller than 12mm and only slightly longer than a fingernail, is capable of producing sounds that reach over 140 decibels.
Scientists have recently discovered that it has a distinct mechanism for generating sound. This includes a particular type of cartilage, a one-of-a-kind rib, and muscle that is resistant to fatigue.
According to experts, these capabilities enable the fish to quickly produce intense vibrations in its cartilage and emit powerful, noisy bursts of sound.
A seldom-seen porpoise was sighted in the Thames River near Gravesend, UK.
The research discovered that the sound created by the fish is linked to the quick compression of its swim bladder and the motion of its fifth rib.
Scientists discovered that the D cerebrum contains distinct muscles that contract and exert force on the fifth rib.
According to scientists, the speed of muscle contraction is breaking records and surpassing the fastest known movement in the animal kingdom.
Upon further examination, researchers discovered that the fifth rib of the fish engages with a groove in the cartilage structure and creates tension by pulling it.
The cartilage breaks off suddenly, increasing its speed by 2,000 times the force of gravity, and collides with the swim bladder, creating a brief and intense sound pulse.
Researchers discovered that the fish has developed genetic modifications that prevent exhaustion in its sonic muscles, enabling it to emit a continuous stream of sonic pulses.
The results, released in PNAS on Monday, question the traditional belief that the rate of skeletal movement in vertebrate animals is determined by their muscle functions.
The findings also provide further understanding of the varying methods used by different animal species to adapt for movement and sound generation.
