Type locality: off Crozet Island (46 ° 16 ’ S, 48 ° 27 ’ E). See: Théel (1886 a: 66 – 67 pl. 4, fig. 6, pl. 16, fig. 6); Heding (1942: 33 – 35, figs. 34 – 36); Massin & Hendrickx (2011: 418). Occurrence: cosmopolitan, known from all oceans except in the Arctic (Hansen 1975); in the Atlantic from the Davis Strait (Heding 1942) eastwards from south of Iceland (Deichmann 1930) and the Rockall Trough (Gage et al. 1985) to the Azores (Marenzeller 1892). Depth: 869 – 4,810 m (Gage et al. 1985); AZO: 2,870 m (Marenzeller 1892). Habitat: soft substrates (muddy sand to ooze; Théel 1886 a, Marenzeller 1892). Remarks: the presence of this species in Azores is based on a single dredge by Hirondelle (sta 248: 41 ° 40 ’ 41 ” N, 26 ° 44 ’ 9 ” W) (Marenzeller 1892, 1893). Though this abyssal holothurian was never re-collected again in the archipelago, more recently A. abyssorum was repeatedly retrieved from the Mid-Atlantic Ridge just north of the Azorean waters (Gebruk 2008; Rogacheva et al. 2013).
