Nassarius snail or whelk?

[Fiver]

I've read a lot of information and looked at a lot of pictures and honestly still cannot tell the difference between the two.

What's your vote on the creature in this picture (there are a few in my tank).

Thanks.

No voting required. It is a buccinid whelk, Gemophos tinctus.
