Ok , I'll take a shot at this one ,As for the textile cone  I think they
live until something like another textile cone that's bigger comes along and
eats it. We sort of learned alot about this from Don Barclays experiments
(Don, even though you didn't consider your theater of living conus serious
science I learned more about conus behaviur then any book writen on the
family , PERIOD!!)
As for gigas , I've seen some real granddads , maybe they are like mercinary
clams  (quahogs) they don't have a true, set cycle of life, they live until
they get eaten. will search the web and see if i can get a real answer.
