The only place known where Dolphin will drive fish to shore, and then follow them right on the beach is the Lowcountry. The Dolphin pods are residents to the inlets here and are not ocean going. As such they have taught themselves new ways to hunt and pass it on to each new generation.
Above several Dolphin drove Mullet to the beach and went up and caught them on shore. You can see a fish by a Dolphin.
The other trick with these Dolphin pods are their followers, Brown Pelicans. Pelicans will push right in to steal the fish.
