Confusing Caption edit

There appears to be no orifice at all on the left side of the shell in this image.Craig Pemberton (talk) 00:22, 21 July 2009 (UTC)Reply

Someone fixed this. Maybe it was me, I don't remember. Craig Pemberton (talk) 08:12, 29 July 2009 (UTC)Reply

Use edit

In the used bookstore today I saw in a book that this structure is used for reaching the surface of the sediment safely so the animal can breathe (like a straw). Is this correct? I didn't buy the book because it was old (70s) and very large and cost something like $14; too much for such an old book. I think the title was something creative like "Shells". Anyways if this is true it would be a great addition to the article. Craig Pemberton (talk) 08:12, 29 July 2009 (UTC)Reply
