Opinions and questions please????

Well I happened to be looking in my invert book for something else when I came across a picture and thought "I recognise that". I've got to say the picture in my book has a better resemblance to your photo than any other pictures on the net but your "worm thing" looks like Caribbean worm snail (Petaloconchus spp.) The book I was reading is The PocketExpert Guide to Marine Invertebrates by Ronald L. Shimek. The link is to an article by the same man but different photos have been used. Worm Snail
