grooves or tunneling?

[stormy88]

<span style="font-family: Century Gothic;"></span>I have a shell i found that has this weird tunneling as if something wormy was munching on the outside of it (i'm sorry, i'm having a hard time describing it!)  I have a picture of it, if anyone thinks they might have an idea, please respond and i can email the picture.  Thanks!

There are numerous marine organisms that tunnel in hard materials, including the shells of mollusks.  These include various worms and mollusks, and even a type of sponge.  If you post the picture I may be able to be more specific.  Or email it to me at <!-- e --><a href="mailtoaulCyp@cox.net">PaulCyp@cox.net</a><!-- e -->
