Bimeria vestita Wright, 1859 Bimeria vestita: Vervoort, 1992: 14–15; Calder, 1988: 21–23, figs 17–18; Marques et al., 2000: 322–324, figs. 1–3; Ramil & Vervoort, 2006: 196–197, fig. 5 no. 2; Schuchert, 2007: 247–250, fig. 20; Schuchert, 2012: 216–217, fig. 205. Material examined. MAURIT-1011, stn MUDR20: 16º08´11”N, 16º56´08”W, 405 m, 7-XII-2010: one colony, attached to Plumularia filicula, no gonophores. MSM 16/3, stn GeoB 14908–1, ROV, 17°40.213’– 17°40.191’N, 16°40.829’– 16°40.289’W, 463–574 m, 16- XI-2010: eight colonies without gonophores, two colonies attached to Lophelia pertusa, three colonies attached to Sertularella gayi, one colony attached to Acesta excavata (Fabricius, 1779), one colony attached to cirripedia. Biology. Bimeria vestita usually grows on other hydroids and on pebbles, algae, sponges, bryozoans, tubes of sabellids and gastropod shells (Genzano & Zamponi 1999; Schuchert 2012). Colonies with gonophores were found in the early summer in the Northeast Atlantic (Schuchert 2012), from October to February in the Mediterranean (Boero & Fresi 1986), August to September in the Northwest Atlantic (Calder 1988) and spring to autumn in the Southwest Atlantic (Genzano & Zamponi 1999). The colonies studied by us were found growing on L. pertusa, A. excavata, cirripeds and the hydroids P. filicula and S. gayi. Distribution. This species has a circumglobal distribution without any records in the Arctic and Antarctic Oceans (Vervoort 2006). In West Africa, it was collected from Morocco (Patriti 1970), West Sahara (Leloup 1937), Canary Islands (Vervoort 2006), Mauritania (Gil & Ramil 2017a), Senegal (Picard 1951), Cape Verde Archipelago (Vervoort 2006) and Ghana (Buchanan 1957). Its bathymetric distribution ranges from 0 (Schuchert 2012) to 405 m (Gil & Ramil 2017a). Our material was collected from depths of 405 to 574 m, representing the deepest record for this species. Remarks. The colonies showed a firm perisarc covering the stem and branches of the colonies that extends as a ...
