Of which mollusc are the acorn and goose the two varieties found on British shorelines?
Goose barnacle Goose barnacle Goose barnacles (order Pedunculata), also called stalked barnacles or gooseneck barnacles, are filter-feeding crustaceans that live attached to hard surfaces of rocks and flotsam in the ocean intertidal zone. Some species of goose barnacles such as "Lepas anatifera" are pelagic and are most frequently found on tidewrack on oceanic coasts. Unlike most other types of barnacles, intertidal goose barnacles (e.g. "Pollicipes pollicipes" and "Pollicipes polymerus") depend on water motion rather than the movement of their cirri for feeding, and are therefore found only on exposed or moderately exposed coasts.

Bean goose geese "Anser fabalis fabalis" wintering in Europe are considered to migrate across three different flyways: Western, Central and Eastern; which has been confirmed by stable isotope analysis of their flight feathers. Bean goose The bean goose is a goose that breeds in northern Europe and Asia. It has two distinct varieties, one inhabiting taiga habitats and one inhabiting tundra. These are recognised as separate species by the American Ornithologists' Union and the IOC (taiga bean goose and tundra bean goose), but are considered a single species by other authorities, such as the British Ornithologists' Union. It is migratory and winters
