Loch Sween NCMPA
This is an important area for mud, and all the animals that live in mud! These include volcano worms, Norway lobsters, shrimps and burrowing gobies. Maerl beds also flourish here. A dense bed of hedgehog maerl runs down the central part of the Caol Scotnish. These create important habitats for other species such as feather stars, scallops, sponges, crabs and fish. Native oysters occur in patches throughout the Loch, which provide food for the otters that live here. Once common in Scotland and supporting a grand shellfish export industry, beds of native oysters now only exist in a few scattered locations. The population within Loch Sween is considered to be of national importance.

Burrowed mud is a surprisingly important marine habitat which supports a rich community of animals. There are the burrow-making animals that live within the mud itself, including fish, worms, brittlestars, crabs and shrimps. Secondly, there are those a
Sublittoral mud and mixed sediment communities
Mud and other sediments below the low water mark which can support a rich variety of life including shellfish, anemones and worms.
Maerl beds include several species of red seaweed, with hard, chalky skeletons. Maerl is rock hard and grows, unattached to the seabed, in little nodules or branched shapes on the seabed. Each bit is quite small, but they can accumulate in large areas tha
Loch Sween contains serpulid reefs, a priority fragile biogenic reef habitat, and maerl beds, another priority habitat. It is the target for focused monitoring survey dives to ascertain the extent and status of these habitats.Learn more about Seasearch
