This is my favorite photo from my low tide walk in Lincoln Park today. These are Sculpin eggs. I didn't see a Sculpin, just lots and lots of tiny eggs on seaweed.
Here you get the 'big picture' of the low tide.

The sea lettuce in this picture was flecked with a dusting of shiny purple specks; my photo does not do it justice.
An anemone closed up tight waiting for the tide to come back and cover him.
