Description
Summary:Obelia dichotoma (Linnaeus, 1758) Sertularia dichotoma Linnaeus, 1758: 812. Laomedea (Obelia) dichotoma – Vervoort 1959: 315– 316. Obelia dichotoma – Millard 1975: 229–230, fig. 75a–b. — Ramil & Vervoort 1992: 243–244, fig. 68c. — Cornelius 1995: 296–300, fig. 69. Material examined SOUTH ATLANTIC OCEAN • 2 colonies, up to 19 mm high, without gonothecae; Vema Seamount, stn Dive 4; 91–95 m depth; 1 Feb. 2015; SEAFO-2015 leg.; SEAFO-2015-40020, SEAFO-2015-40131. Distribution Obelia dichotoma is a well-known species with a nearly cosmopolitan distribution (Cornelius 1995); it is absent from Arctic and Antarctic waters (Peña Cantero & García Carrascosa 2002). In the Southeast Atlantic, it was reported from Angola (Vervoort 1959, as Laomedea (Obelia) dichotoma) and South Africa (Millard 1975). Its bathymetric distribution ranges from the intertidal (Cornelius 1995) to 540 m (Vervoort 2006).
