Two years ago Blue Planet changed the way we see our oceans forever.

David Attenborough's narration and the striking images even changed laws - with plastic use now at the forefront of social consciousness.

Blue Planet live takes us across the globe allowing us to see some of the world's greatest creatures in their natural habitat - with the next episode airing later tonight.

One of those involved is Marlow's own celebrity naturalist Steve Backshall.

Steve Backshall, Naturalist:

"So I'm on the top deck of our dive boat, all around me I can see black seas and stormy skies. Below me in the water are lots of silhouettes of sharks.

"I'm in the Bahamas, and it's very much based around the sharks and rays, and how they are doing.

"The amount that are being taken out of our oceans every single year is phenomenal... possibly as much as 100 million."
