“It’s like a big fish made out of fish,” my 10yo son Henry just noted, “Fishception!”

Kottke, who says “Scary Sea Monster Really Just Hundreds of Tiny Fish in a Trench Coat,” notes:

“Try rewatching the video, picking one fish and following it the entire time. Then pick another fish and watch the video again. The juvenile striped eel catfish seem to cycle through positions within the school as the entire swarm moves forward.”

Like riders in a peleton, each taking their turn braving danger at the front.
