I think maybe I've worked out what it was that I found on the beach near Cape Canaveral some months back. It was an egg sac, but what kind of egg sac? It looked like telephone cable with a connecting cord to which eack sac was attached. Each little sac reminded me of the paper nautilus, but I knew that their egg sacs were quite different. I'd like to know exactly what the actual name of the whelk is? Each egg sac was a good 1/2 inch in diameter. The overall length of the spiral was approx. a foot long.Thanks for any input. Pat Diver.
