On the fauna of Corallina officinalis L. in western Norway

Three localities south of Bergen, one sheltered, one semi-exposed, and one very exposed, were chosen. Samples of Corallina were obtained at various times of the year from the intertidal and sub tidal zones at the two more exposed localities. At the sheltered locality samples were taken from just below the intertidal zone only.Some 70 species and several higher groups were recorded and in most cases counted. The size of the animals found living on the plants is considered in relation to the form of growth of Corallina and the faunal composition in relation to the degree of exposure
