The magical pictures show a pod of at least eight hundred dolphins diving into the water to catch fish.
The speed at which the mammals chased after the fish is shown by the stream of bubbles they left in their wake.
The incredible scenes astonished photographers Rainier and Silke Schimpf as the dolphins hunted their prey.
The duo live in Port Elizabeth, South Africa, and captured the common dolphins along the coastline between Mossel Bay and Port Alfred in March.
Pods of up to a thousand common dolphins are common from February to June as they hunt their fish.
Rainier said: “Each muscle and drop of Indian Ocean saltwater is visible on these streamline creatures, which swim at speeds of more than 25 knots per hour and travel fast distances of more then 150 km per day.
“They eat fish including mackerels, mass bunker and sardines - if they can out swim them they will herd it together and feed on their prey.
“A dolphin can feed up to 20kg of fish a day.
“They were not irritated nor harmed by the ship, they accepted us next to them and we watched closely how they gather fish up to the surface and eat them.”
