Keller Laros was doing a night dive in a swarm of manta rays, which is awesome in itself, when a dolphin swam up and “asked for help” with a hook and trailing monofilament. Keller spent the next few minutes working to cut the line free and remove the hook. The dolphin continued to maneuver to facilitate the removal. This is cool to watch.
