Video: Humpback Whale Sleeps Upright

Humpback whales need to sleep near to the surface in order to get air regularly. This diver came across the body of a whale sticking out near the surface of the ocean, so went underwater to see what was going on. He got this incredible footage of the whale suspended vertically in the water, before swimming away.
