A tiny aquatic animal can produce voice up to 99.2 decibels and it is recorded as the loudest noise produced by the animal of of its body size ever.
A newly conducted study revealed that water boatman, an aquatic animal of a very small size is the loudest animal compared to its size producing a much audible sound than a normal one.
It does this by rubbing its penis with its abdomen in a special natural process known as stridulation. This process is a part of reproduction phase as this sound is produced to attract the mate. The size of this tiny boatman, named as Micronecta scholtzi, is merely 2mm.
If you scale the sound level they produce against their body size, Micronecta scholtzi are the loudest animals on Earth.
The researchers used specialized underwater microphones to record different pitches of voices and found out that the average of the sounds produced by this insect reaches up to 78.5 dB which is comparable to a nearly passing freight train.
The researches, at first could not believe that this mighty voice is coming from an animal so small. Dr. James Windmill from the University of Strathclyde, Glasgow said:
We were very surprised. We first thought that the sound was coming from larger aquatic species such as a Sigara species [of] lesser water boatmen. When we identified without any doubt the sound source, we spent a lot of time making absolutely sure that our recordings of the sounds were calibrated correctly.
According to a group member of this research team, the sound is so much that a passerby can hear it from the deep depths of the ocean.
The song is so loud that a person walking along the bank can actually hear these tiny creatures singing from the bottom of the river.
Researchers believe that male insect produce such a mighty sound in competition with other males to attract the female insect. 😀
