I saw the Derussa Clam post and didn't realize that there was a difference. If they are Whelks and not Nass', it would explain why they don't bury themselves in my sand-bed. I have four of them. I bought 1 Nass. Snail from a different LFS and it was about 3 times the size of the one in the pic and I only see it periodicly.
