Grinning: Bruce the smiling great white by Sam Cahir (runner up sharks)
These stunning pictures are some of the winners in one of the world’s biggest underwater photo competitions.
From grinning great whites to colourful nudibranchs and underwater strip poker players it runs the whole spectrum of water related photography.
And with 12,000 entries from 123 different countries submitted to the underwaterphotography.com website, some of the top prizes have gone to British snappers. The competition covers 16 categories from wrecks to sharks to close-up and freshwater shots.
Nick Blake won a gold medal in the freshwater category for a London cab underwater at Wraysbury Lake near Heathrow Airport.
He also got a runner up prize in the topside (above water but marine related) category for his roly-poly grey seal balancing precariously on a rock on St Tudwal’s Islands north Wales.

Fellow countryman Paul Colley also won gold in the wrecks (wide angle) category for his full-length picture of the newly-sunk USS Kittiwake in the Cayman Islands.
Other winners include a savage looking fang tooth moray eel, a humpback whale off Hawaii, a duckling in the water photographed from underneath and a weird looking siphonophore shot in the cold waters off Norway.
