The species is redescribed and its North East Atlantic distribution delimited Tethya norvegica is compared, on the basis of morphometric and electrophoretic features, with T. aurantium and F.citrina . Morphological, morphometric and electrophoretic data suggest that I norvegica is a distinct biological species.
