Beachy Head West MCZ
This site is actually two spatially separate areas in the south-east of England. They run parallel to the East Sussex coastline extending from Brighton to the Beachy Head Cliffs near Eastbourne. This protects a total area of approximately 24 km2. Here, chalk reefs and gullies are home to a wide variety of animals, including the rare short-snouted seahorse. Seahorses have excellent eyesight and hunt for their food by sight. They feed on a variety of small crustaceans, such as shrimp, but do not have teeth so instead suck food up through their snouts.
Forests of kelp are found in the shallow areas here, whilst ridges and gully sides are covered with tightly packed blue mussels mixed with native oysters. Species such as lobsters, spider crabs and hermit crabs are also found here
MPA TypeMarine Conservation Zone
Marine Conservation Zones (MCZs) are designated under UK legislation (Marine and Coastal Access Act 2009) and have been established around England, Wales and Northern Ireland to contribute to the UK MPA network protect a range of nationally important marine wildlife, habitats, geology and geomorphology, and can be designated anywhere in English and Welsh territorial and UK offshore waters.

Moderate energy circalittoral rock
Deeper water rock, with some shelter from waves and currents.
A very rich and diverse muddy undersea habitat that supports high numbers of worms, cockles and other shellfish, urchins and sea cucumbers as well as sea pens, burrowing anemones and brittlestars.
Sandy seascapes that can seem a bit like deserts, but can be full of life. Flat fish and sand eels camouflaged on the surface of the sand,worms and bivalves (with their paired, hinged shells) all live in places like these.
Subtidal mixed sediments
Undersea beds of a mixture of stones, gravels, sands and muds. Because mixed seabeds are so varied, they may support a wide range of animals, both on and in the sediment.
High energy circalittoral rock
Rocky areas affected by strong waves or currents where the water depth means there is not enough sunlight so marine animal communities like sponges, sea firs and soft corals dominate and seaweeds are mostly absent.
The chalk we see on our coastline can continue below the tide and create a very rich habitat for marine life. Becasue chalk is soft it is vulnerable to damage.
Intertidal coarse sediment
Where small rocks, pebbles, and gravel, sometimes mixed with coarse sand are sometimes covered by the tide. While it may not look like much lives there - there are animals specially adapted to live in the moist spaces between the shingle and gravel.
Blue mussel beds (Mytilus edulis)
These small, blue mussels are a common sight on UK coasts and form large beds in some places. They are particularly important where they create a haven for other creatures like starfish, crabs and anemones in otherwise sandy or muddy areas.
Littoral chalk communities
Special communities of animals and seaweeds that live on chalk seashores. Chalk is a soft, pure limestone and is easily eroded by seawater. This results in a characteristic type of beach, with a wide shore, often extending for many hundreds of metres, ba
Native oyster beds (Ostrea edulis)
Native oysters are two shelled animals - one half is like a cup and attaches to the rock, the other is flat and forms a lid. In shallow water on fine, muddy sand, they can be found in huge numbers and form extensive beds, which become home to many other m

There has been Seasearch surveying at this site as for back as the 1990s by Robert Irving and partners at Sussex Seasearch. These early dives helped to identify Sussex Marine Sites of Scientific Interest.Learn more about Seasearch
