Check out this craziness. According to recent Internet story, a half inch long fish can generate some amazingly loud racket.
Quoting here a few lines from the story:
"Danionella cerebrum, a species of fish discovered only about three years ago, are tiny translucent fish that live in shallow streams in Myanmar. They are no more than 12 millimeters long and have a "unique sound-generating" organ that can make noises of more than 140 decibels, an international research team said in a news release Tuesday.
"To make noise, the fish hits the drumming cartilage against its swim bladder, a gas-filled cavity or organ that is predominantly used to control buoyancy, the study says. The movement produces a rapid pulse in high and low frequencies.
"This apparatus accelerates the drumming cartilage with a force of over 2,000g and shoots it against the swim bladder to produce a rapid, loud pulse," Britz said. "These pulses are strung together to produce calls with either bilaterally alternating or unilateral muscle contractions.
“We assume that the competition between the males in this visually restrictive environment contributed to the development of the special mechanism for acoustic communication,” Britz said."
Wow! That is crazy. The incredible things that Science is discovering on a daily basis. Amazing.
