"Captured during a daytime dive at Blairgowrie Pier in Port Phillip Bay, Australia, this shorthead seahorse was feeding near the surface and freely swimming from one floating piece of weed to the next. I’m not sure if the seahorse mistakenly grabbed hold of the pipefish with its tail, confusing it for a piece of weed, or if this was deliberate. The pipefish immediately struggled to break free from the seahorse’s grip. This interaction lasted only about 10 seconds, which was just enough time to set up the shot."
