Scientists think the algae might form into balls to protect itself from hungry fish

I would guess that wave action forms them.

Hmmmppfff!

Now which is more logical -- the single-cell plants get together and have a meeting, and one of them says, "These fish are eating us alive! We've got to do something! Anyone have an idea?" And then one of the single-cell plants speaks up and says, "Maybe we could form ourselves into balls -- would that help?" And the other single cell plants say, "That's a great idea! Let's do it!!"

Or -- by your preposterous theory -- the ocean has "waves" which "shape things".

Like Lake Michigan ice balls, only warmer ...
