A 15-foot-long great white shark found washed up on a beach in South Africa had just eaten a dolphin — before it was itself ravaged by an even bigger predator, in a first recorded in the region.

15-foot shark found on South Africa beach finished eating 6.5-foot dolphin when it was attacked by bigger predator, study says.

Beachgoers witnessed the circle of life up close Sunday as a shark feasted on a dolphin off the coast of Torrey Pines State Beach.

A group of what appears to be juvenile sharks were caught on video at Torrey Pines State Beach feeding on a dolphin just off the coast.
