After so many years, I finally found this tiny transparent fish called Sundasalanx microps!!!! It is about 2cm long. You can even see the air bubble inside its stomach!!! I never expected to find it so near to my home!
I just observed the stomach of Sundasalanx microps....it contains the air bubble! I saw a small bubble came out from it to the gill & then released out. It is so amazing to see everything through it's transparent body.
