English: FIGURE 11. Osedax jabba n. sp., previously Osedax ‘spiral’; sp.1 SBJ-2006. A. Image of live paratype (SIO-BIC A7837) female, still in tube, collected at 2898 meters in November 2009. Much of trunk is still relatively expanded, but anterior end is contracted (arrow points to tip of trunk) and trunk has pulled back along the tube. Mass of fine roots is attached to several small pieces of bone. B. Ventral view of same specimen (SIO-BIC A7837) with sediment-covered part of the tube peeled away to show the transparent trunk (arrow points to tip of trunk). Large ganglion is visible in ventrolateral region of the trunk. C. Close up of dorsal mid-trunk of paratype (SIO-BIC A7837) female, showing oviduct filled with oocytes and an adjacent blood vessel. D. Another close-up of oviduct, more posteriorly near base of trunk, showing some dwarf males in vicinity of oviduct. Oocytes ellipsoidal, 150 μm by 120 μm. E. Living holotype (SIO-BIC A7832) collected October 2007 at 2898 meters with tube dissected open to show main trunk, which has largely ‘deflated’. Oviduct can be seen running along the trunk. Tube also contains lower trunk and ovisac region. Arrow points to position of where 10 dwarf males were found in lumen of tube against body of the female. F. Close-up of large ganglion in trunk of paratype (SIO-BIC A7837) female, seen in Figure 11B.
