Some people will have access to fish markets in tropical locations, others may only have their local shop. It doesn't have to be an exotic animal like a shark, marlin or swordfish, even the humble fish finger (fish stick) was once a wild animal.

So next time you go shopping, use your camera to show us which marine wildlife is for sale in your local area and post them on Twitter and Facebook using the hashtag #Wildlife4Sale.
At the end of the campaign Blue Planet Society will publish selected photographs to help expose the global trade in ocean wildlife and the threat it poses to the marine ecosystem.
