Dead Common Dolphin washed up on the Bigbury-on-Sea beach in Devon, United Kingdom. Next to the dolphin a sign says "Killed by Bass trawling, write to your MP today!" The Whale and Dolphin Conservation Society (WDCS) estimates that some 4000 dolphins and porpoises per year may die in pelagic trawl fishing nets in this region, which is 5% of the population.
