Intriguingly, these wild fish appeared to recognize the specific diver who had previously carried food, choosing to follow only them while ignoring other divers. For years, scientific divers at a research station in the Mediterranean Sea had a problem: at some point in every field season, local fish would follow them and steal food intended as experimental rewards.
