After posting our comments on this outstanding film shown on PBS TV last Sunday evening, and adding that a video could be purchased we received numerous inquiries as to where?  After calling the TV station, the following information is passed along to those who are interested in securing a copy.
The show was Nature Series Show#1508 and can be purchased by calling 1-800-336-1917.
I believe this show impressed a lot of viewers who are not conchologists as the lady I was speaking to at TV station stated she watched it and wanted to talk all about it and she is not a collector. Others have said the same.
If you did not see it, look for it next time or get the video.
Hope this helps those who contacted us.
Best to all
