Hi everyone! This is another first for me. We had a high tide like no other last night because of storm and full moon. I find this on the beach. Really don’t know what it is. I think it is an enchroid. Most likely I’m wrong because I am no knowledgeable with this kind of stuff. It’s rough like sandpaper and about 1.5 inch in diameter. I don’t think my pictures are great but any opinions are much appreciated!
