Crickets: Insect from the South African Jungle Might Prove Beneficial for Researchers
In the November 16 issue of the US journal "Science", an exclusive study about the sighting of a microscopic organ that acts as a "middle ear" for the crickets has been published.
There is no doubt to say that the South American bush crickets, which are also known as the katydids, are famous for their smallest ears among all the creatures on Earth, but then what makes them remarkable is the fact that their ears function in a remarkably similar way to that of human ears.
In simple words, this South American Jungle insect features a distinct physical structure of ear but it works the same way as that of human's.
This proves to be quite beneficial for the researchers as now they can research over new proceeds in hearing aids and medical imaging with the help of these tiny creatures.
Katydid's ears have an exclusively different evolutionary history. But then they too work in a three-part process. The eardrum is responsible for collecting the sound, middle ear converts it from air-born noise into liquid-born vibrations, and then finally there is a formation called the cochlea that examines the frequency.
Scientists were very much aware of the presence of cricket's eardrum-like apparatuses on their two forelegs, but then they were confused to learn that how these crickets are actually allowed to hear from these internally-connected tympana with the sensory receptors.
