World's smallest vertebrate is a member of the carp family of fish.© Kottelat, Cornol/Raffles MuseumPaedocypris progenetica is the smallest fish in the world at 7.9mm long!  The fish were found on one of Indonesia's islands. The fishes body looks like a larvae. Since its body is so small the head skeleton has been reduced in size. The fish has no bone protection for its brain. The  water is the color as dark tea and has the acidity of Ph3 which is around 100 times more acid as rain water!
