Figures & data

Figure 1.  Deep-sea cephalopods from the northern Atlantic: (A) Teuthowenia megalops (Prosch, 1847), (B) Benthoctopus johnsoniana Allcock et al., 2006, (C) Histioteuthis corona (Voss & Voss, 1962), (D) Mastigoteuthis agassizii Verrill, 1881, (E) Stauroteuthis syrtensis Verrill, 1879, (F) Promachoteuthis sloani Young et al., 2006, (G) Helicocranchia pfefferi Massy, 1907, and (H) Opisthoteuthis grimaldii (Joubin, 1903); the photographed specimens were obtained during three expeditions to the northern Mid-Atlantic Ridge, the RV James Cook cruise, 2007 (www.oceanlab.abdn.ac.uk/ecomar/) (A, G), the RV Bigelow cruise, 2007 (http://www.vims.edu/blogs/mareco/) (B, F, H), and the RV G.O. Sars cruise, 2004 (www.mar-eco.no/) (C), and during the R.V. Seward Johnson and Johnson Sealink submersible cruise, 2004, in the Gulf of Maine (www.at-sea.org/missions/maineevent5/preview.html; Jacoby et al. 2009) (D, E); for distribution and abundance information on these eight and 48 other cephalopod species see Vecchione et al.
