50-tonne whale surfaced under a kayak off South Africa coast

This is the heart-stopping moment a 50-tonne whale surfaced off the coast of South Africa, lifting a kayak carrying two people out of the water, when they were paddling with others near Cape Town off South Africa's south west coast. The giant Southern Right Whale swam down beneath them.

Moments later, it came to the surface and lifted the boat out of the water, holding it on its back while shocked tourists watched on.
