Flapper skate (Dipturus intermedius), the world’s largest skate species measuring over two meters in length, live hidden on the rugged seabed around Scotland. Their life in the darkness, deep underwater, makes it extremely difficult to find out more about their whereabouts and movements. However, there is considerable interest in these animals. As predatory fish at the top of the marine food web, they play a very important role in marine habitats and the balance of marine ecosystems.
