> Don,
 
I haven't a clue as to depth but I was intrigued by the "herd of Conus
quercinus."  Did you really mean a herd?  I know you will find Strombus
thersites traveling in a herd or colony but this is the first I have
heard of a Conus herd.  That would be like a herd of prehistoric
veloceraptors of the shell world!  Does anyone on Conch-L have
information on other species that may travel in groups?

and some of you would even call the first 3 feet mud)
