When Rainer Schimpf was diving off the coast of Port Elizabeth, South Africa, to watch the annual sardine run, he came across an unexpected visitor -- a 50-foot-long, 40-ton Bryde's whale.

The sardine run attracts a variety of predators, including sharks and birds, but Schimpf was not prepared for the whale who was attempting to go for a shoal of fish nearby. Schimpf was right in the line of attack, but luckily the giant swerved just at the last minute to avoid the diver.
