Studland to Portland

Site overview: This site lies off the south coast of Dorset and contains lots of different types of underwater reefs. For example, there is a series of limestone ledges (up to 15m across) which stick out of the shelly gravel at Worbarrow Bay. These are home to a rich sponge and sea fan community. Beautiful brittlestars have made their home on shale reefs extending from Kimmeridge; a unique reef feature, known as St Albans ledge, extends out over 10km offshore. Mussel beds flourish at Portland Reefs.
