Underwater photography: marine wildlife off British shores

This year's winning photo is of a male corkwing wrasse building a nest, by Robert Bailey. The male wrasse scours the shallows looking for a suitable nook or cranny in the rocks, then spends several days carefully selecting pieces of seaweed with which to decorate and line it. This should attract a female to leave a clutch of eggs Photograph: Wildlife Trust/Robert Bailey
