Mr. Fletch;
First, remember down here the " puffer fish" is known as the "blow fish".
I have noticed this condition with the ones from the west coast. This phenomenon greatly concerned me as I have undieing devotation to all living creatures. That is, save one I will not mention. Now,I have the correct answer. I came too this conclusion from many years of scuba diving and study. If you remember years ago Rock Hudson died. Not wanting to be put in the ground he wishes were to be cremated and the ashes spread to the wind and sea. All the fish in the sea went to the bottom except the blow fish. There are obvious reasons for this as my study has proclaimed.
The thesis for my doctorate was on this very subject. If you would like to dicuss my theorum any futher, please PM me as this forum is not to bore all others. Thanks for bringing this up.
God save the little fish'.
