Indonesian flip off?

Checking out pics from a recent trip, I find that one subject may have followed Monty Python's suggestion and waved its personal parts at me...

Or is it an Indonesian Flip Off or perhaps an offer?

Since I am new to Indo diving and limited in Pacific diving, I do not have a book on this guy.

It may be common but not to me. So what is this?

thanks

Dave

Perhaps a cowry [see the mantle split?], but not one I've ever seen.

Did you "wave" back?

I believe it's a mole cowry.

I agree. Talparia talpa

Thanks for the ID for me.
