Wild Pacific – Grey Reef Sharks

Description: One ocean. 20,000 islands. 25% of the Earth’s water. The Pacific Ocean is unimaginably vast. You could fit the whole of the world’s landmasses into it with room left over for another Africa. It stretches from the heat of the tropics to the sub-Antarctic - coral gardens thrive in its warmest waters - and icebergs float in its coldest. The distance between its islands can be huge, literally hundreds, even thousands of miles. And yet, life made it there. This July, BBC Earth brings to Blu-ray and DVD a stunning, high definition voyage of discovery through this unique and fascinating oceanscape - Wild Pacific.
