A miniscule, transparent fish makes drumming sounds as loud as a jackhammer, say researchers.
A tiny, transparent fish makes a sound as loud as a pneumatic drill, scientists in Berlin have discovered.
Scientists have known that other creatures, such as the aptly named pistol shrimp can create very loud noises as they hunt other species, up to around 200 decibels. "It turned out that they're coming from the fish themselves. And it's extraordinary, because they're so tiny and so loud." Much of this sound is reflected back into the water so when humans stand beside the fish tanks, they hear these pulses as a continuous buzzing sound.
The researchers argue that the drumming mechanism that the fish use is a very sophisticated instrument.Many species use their muscles to drum on this bladder to produce sounds but danionella goes several steps further.
