From precious coral and slimey sea cucumbers to luxury fish lips and beautiful seahorses, this month Naked Oceans explores the many ways we trade the oceans.

We sift through some of the highest price-tags in the sea and find out what impact this all has on ocean life. Helen pays a visit to an aquarium that breeds seahorses and finds out how to mail them around the world. And we ask, Is Blue Carbon the new green? Will converting marine life into carbon credits help fend off climate change? And in Critter of the Month we meet a very rare animal, with a very big appetite.
