Overview: Ray makes his way to the Isle of Mull in the Inner Hebrides looking for marine and coastal wildlife. He meets up with local whale watching skipper James Fairburns as they look for the signs of minke whale and he comes face to face with the world’s second largest fish after he snorkels with a huge basking shark. He finds it hard to stay on his feet as the boat takes him to the epicentre of the Corywreckan whirlpool.
