Jimmy Liao, an assistant professor of biology at the University of Florida has made a spooky fish discovery, according to a video posted to YouTube. It involves wave action from stream eddies and a dead trout.

In the video, Liao explains that trout use swirling water eddies to conserve energy as they migrate. And models he’s developed in his lab show how trout utilize the wave action perfectly.

To knock the point home, Liao then shows how a dead trout’s body moves when placed in swirling water behind a large rock. The fish moves exactly like live trout do.

“So we tethered a dead trout in an artificial stream in my lab,” said Liao in the video. “And (we) swam it behind a boulder. What we found out is going to shock you.”
