Distribution and Ecology . The species has only been recorded previously from the type locality (Northwest of France ) and the Gulf of Cadiz. The type material was found at 1035–1080 m depths ( Băcescu 1981 ), but no additional ecological information was provided. In the GoC Apseudes setiferus has a wide bathymetric distribution, between 350 and 2200 m depth (see also Błażewicz-Paszkowycz et al . 2011 ). It was found on coral mounds of the PDE and mud volcanoes of the El Arraiche field (Kidd, Meknès , Lazarillo de Tormes and Gemini) Carbonate Province (Ginsburg, Yuma) and Deep Field (Carlos Ribeiro). Substrates include mud with coral and molluscs debris and in mud breccia with hydrogen sulphide (H2S). It was generally found in low densities with a maximum of 12 individuals.m - 2 in quantitative samples, and at a maximum of 5–10 cm depth into the sediment.
