Hmmm...somehow wonky fake boobage seems at odds with mermaid-y-ness...? (same applies to the Tony Mauro I suppose.)
After careful examination - in the service of science - of Anzilovs complete works of 30 years of photographing nude girls under water, I've come to the conclusion that the female breast has approximately the same mass as the very salt water of the black sea. In other words it is not salt water inside the breast, but salt water surrounding the breast, which causes what we scientists know as the "wonky boobage-effect".
It is the same physical phenomenon, that allows the fascinating dialogue between breasts and jellyfish, as seen in the second picture.
