I remember one time some years ago, when I didn't know anything about shells, nor did I care, there was a large storm on Pensacola beach. After the storm I went out to see if anything interesting had washed up. For miles you could see these black "blobs" strewn over the beach. I touched one. It felt slimy, so I jumped back. After a while I had become brave enough to pick one up. So I picked it up. Curious, I squeezed it. A jet of purple dye soaked my shirt. It looked like someone had sprayed me with grape juice. I had to throw the shirt away. I now look back on it and realize that the blobs were Sea Hares. An excellent source of royal purple dye! Kindest Regards, James
