Examples of moderate energy littoral habitats:

As wave exposure decreases, the threat of becoming dislodged reduces and the organisms that were confined to the crevices can extend across the shore. Seaweed fronds are less likely to become ripped, so forms are no longer stunted. A patch work of barnacles and seaweeds appear with gastropods grazing on juvenile larvae of both; helping to maintain a balance in the competition for space. Mussels sometimes come to dominate and form beds amongst the barnacles. Organisms that are less robust also begin to appear but are once again often confined to the more sheltered crevices.

Below are images of the two habitat complexes within moderate energy littoral rock habitats:

Large  Mussels (Mytilus edulis) can sometimes form beds on moderately exposed shores. Habitat Classification: LR.MLR.MusF (Mussels and fucoids on moderately exposed shores)
