A frog that appears to be giving double peace signs and jet-propelled marine salps were among creatures captured by photographers vying to win awards at a wildlife photography competition.

David Hamilton’s ‘sea salps’ - a marine animal which moves through the water by contracting its muscles - scooped an award in the Ocean Wonders category of Cornwall Wildlife Trust’s contest.

Photography captured by the six winners is now on display after a ceremony at Truro Cathedral.
