Occurrence: Northeast Atlantic, from the Charlie-Gibbs Fracture Zone in the Mid-Atlantic Ridge and off SW Ireland (c. 53°N, 20°W) to the Bay of Biscay and the Azores (A.M. Clark & Downey 1992), possibly in the Canaries and Madeira as well (Perrier 1894, Koehler 1909); the subspecies P. agassizi agassizi Verrill, 1880 is known from south of Newfoundland to the Caribbean and the Gulf of Mexico, as well as the Cape Verde Archipelago, Ascension Island and South Africa (A.M. Clark & Downey 1992). Depth: 969– 4,252 m (Dilman 2008); AZO: 1,165 –2,178 m (Koehler 1909). Habitat: soft substrates, ooze to muddy sand and rock (Perrier 1894, Koehler 1909). Remarks: through the historical literature, several Plutonaster species were described from the Azores, including two species by Sladen (1889) based on specimens collected by H.M.S. Challenger in the Azores: P. notatus (sta 73: 38°30’N, 31°14’W, 1,829 m) and P. abbreviatus (sta 78: 37°24’N, 25°13’W, 1,829 m). Perrier (1891, 1896a) described P. granulosus based on the material collected by Hirondelle in the same area. The ... |
