Abstract

Living specimens of the amphi-Atlantic asteroid Hacelia superba have been collected in different areas of Gazul mud volcano in the Gulf of Cadiz, south-western Iberian Peninsula, at depths of 380–487 m. This starfish displayed low abundances (~1 ind. 2000 m−2) in beam trawl catches on the mud vulcano and adjacent soft bottoms. The absence of previous records in this area could be due to a low sampling effort on bathyal hard bottoms of the Gulf of Cadiz, especially those of dormant mud volcanoes, as well as a possible misidentification as Hacelia attenuata that also occurs in the area but is restricted to infralittoral and circalitoral bottoms.
