Sertularella rugosa (Linnaeus, 1758) Fig. 37 Sertularia rugosa Linnaeus, 1758: 809. Sertularella rugosa.— Segerstedt, 1889: 17, 26.— Lönnberg, 1903: 60.— Jäderholm, 1909: 101, pl. 11, fig. 14.— Gislén, 1930: 346.— Rees & Rowe, 1969: 18.— Jägerskiöld, 1971: 64.— Cornelius, 1979: 290. Type locality. UK: England, Brighton (Cornelius 1979: 290). Museum material. Kosterhavet, 58°53.093’N, 11°05.668’E, 20–30 m, 09.ix.2010, biological dredge, R / V Nereus, one colony, up to 6 mm high, on Flustra sp., without gonophores, ROMIZ B3910. Remarks. Unlike many species of hydroids, the synonymy of Sertularella rugosa (Linnaeus, 1758) is uncomplicated (see Cornelius 1979). Some authors (e.g., Cornelius 1979, 1995b; Schuchert 2001a) have suggested that Sertularella tenella (Alder, 1856) may be identical with S. rugosa (Linnaeus, 1758), but the two seem quite distinct morphologically. Rees & Rowe (1969) noted that S. rugosa is common on colonies of the bryozoan Flustra in western Sweden, and it was found on that substrate in the Kosterhavet during this study. Kramp (1935b) reported it to be common in shallow waters (0–35 m) along the Danish coast on substrates such as algae, other hydroids, the bryozoan Flustra foliacea, and the sponge Halichondria panicea. Christiansen (1972) found it on the same species of sponge in the Oslofjord. The association of this hydroid with Flustra foliacea was described in Stebbing (1971). Reports of this boreal species from the tropical eastern Pacific and from Peru by Fraser (1938, 1948) seem questionable. Reported distribution. West coast of Sweden.—Kosterfjord to southern Kattegat (Jägerskiöld 1971). Elsewhere.—In the northern hemisphere from the Barents and White seas to western France (Linko 1912; Naumov 1960; Cornelius 1995b) in the eastern Atlantic, from Greenland and Labrador to Long Island Sound (Schuchert 2001a; Calder 2004) in the western Atlantic, from Alaska to California (Fraser 1948) in the eastern Pacific, and from the Bering Sea to Japan (Yamada 1959; Naumov 1960) in the ...
