The shallow shelf-sea waters around the British Isles are home to a wide variety of marine megafauna, including 24 species of whales and dolphins, myriad seabirds, the world’s largest population of grey seals as well as the basking shark, the second largest fish in the world.
Although many of these species are protected by law, they remain vulnerable to a number of threats. Some are direct, as in the case of fisheries that cause entanglement in nets, and can be regulated against in extreme cases through restrictions on the sale of by-caught animals, for example. Others are more subtle however, and are related to the public desire to observe marine life in the wild, or are a by-product of the dramatic increase in the recreational use of coastal waters.
