…a law, even, against the single panel.

I sit here, dumbfounded. Searching. Wanting to say something. I think to myself (much like Mark is now..) “This is like the cave all over again… There are different ways to be trapped, even on top of the water within a paddle-board’s distance from shore…”
Of course they are fish! What else is going to live in the water?! I guess the “suspense” is in asking the question, “What’s causing this phenomenon?” Predators (probably billfish of some sort) are working together to form a bait-ball and have a little dinner. The fish, forced to the surface, are easy pickings for the gulls, and they are grateful. Mark, the supposed naturalist, is transfixed. Next.
