Diver narrowly avoids being swallowed by a 40-tonne whale

Right, we're never going swimming again.

This diver had a lucky break when he narrowly avoided getting swallowed by a whale.

Rainer Schimpf was filming the annual sardine run near Port Elizabeth in South Africa when the 49-foot-long Byrde’s whale swam up from the depths to feed on the fish.

The video shows just how close the whale came before swerving at the last minute to avoid him.

Schimpf was knocked back by the force of the huge creature as it breached, but was uninjured.

He captured some amazing pictures of the whale swimming up from beneath him before it disappeared back into the ocean.

Remind us never to come between a huge whale and their dinner.
