A "hunting pair" comprising a large blue runner, swimming above and behind the stingray. The two eat different things and their hunting together helps both. The larger stingray profile startles small fish that make food for the runner, while the runner protects the stingray's back. St. Eustatius (Statia), Netherlands Antilles.
