Remarks. Hydroids of Sertularella tenella Alder, 1856 somewhat resemble those of S. rugosa (Linnaeus, 1758) in being relatively small and in having annulated hydrothecae. Cornelius (1995b: 82) listed six characters useful in distinguishing S. tenella from its congener: (1) the aperture is perpendicular to the hydrothecal axis rather than being outward-inclined, (2) hydrothecae are widely separated vertically rather than being bunched together, (3) a notch is absent just below the rim on the abcauline wall of the hydrotheca, (4) hydrothecae are adnate for about ¼ rather than ¼–½ of their length, (5) the number of hydrothecal annulations is 5–6 rather than 3–4, and (6) its typical substrate is usually other hydroids rather than flustrid bryozoans. Records indicate that S. tenella is common along the coast of western Sweden from the mid-Kattegat northwards (see Checklist). By contrast, it is reportedly infrequent in Danish waters (Kramp 1935b) and in the Oslofjord (Christiansen 1972).
