@annied Thank you. I found it dried out on the tide line. Am not sure whether it is classed as sea weed or not. Hopefully someone will enlighten me. Or I could google it!
I knew this was yours as soon as I saw it. Lovely shot again. This might be mermaids purse which is an egg case of sharks etc... You didn't know I was so well informed - ok I have just googled it for you as I knew it was some purse.
