FIGURE 9. Osedax jabba n. sp., previously Osedax 'spiral', sp.1 SBJ-2006. A. Anterior end of whale fall 'Ruby' at 2898 meters in September 2004. Baleen is prominent on surface of sediment in foreground with tubes (white arrows) of large chaetopterid annelid Phyllochaetopterus gigas (see Nishi & Rouse 2014). Little bone obvious on sediment surface. Background has a cluster of more than 10 Osedax jabba n. sp. (black arrow) with their tubes coming directly out of the sediment. B. Cluster of more the 10 (black arrows) Osedax jabba n. sp. at 2898 meters in November 2004. No obvious bone on the sediment surface. C. Two specimens of Osedax jabba n. sp. at 2898 meters in November 2005. Two prominent red blood vessels are visible through the tube of each specimen and these indicate the trunk is occupying whole of tube and is coiled anteriorly. Trunk does not appear to emerge from tube. D. Lateral view of an Osedax jabba n. sp. specimen emerging from sediment surface, though adjacent to a piece of bone, at 2898 meters in January 2006. Blood vessels are visible, indicating trunk is filling tube.
