We used to call tiny pieces of seaweed Cornflakes. In the mornings you’ll only see a few because its been calm all night and all the cornflakes have settled into behind the banks. Once the tide comes in and the wink rears up it’s over.
The surf will get thick with dense orange/red flakes, amongst which there will be a few jellyfish bopping around. It feels like swimming through Minestrone soup.
It’s pretty gross.
