English: FIGURE 14. Osedax lehmani n. sp., previously Osedax ‘yellow collar’. A. Several adult females on rib bone of a gray whale calf (Eschrichtius robustus) that was deployed at 385 meters in Monterey Canyon. Rib was recovered to study the Osedax in an aquarium setting. Note distinctive yellow ring around most of the anterior end of trunk. The massive circulatory system in trunk and palps is evident from red color of worms. B. Micrograph of live paratype 4 (SIO-BIC A7808), a female, in dorsal view dissected from gray whale deployed at 385 meters. The ‘root’ mass is a single lobe extending away to the right of ovisac. Palps are retracted and partly curled, with pinnules all oriented dorsally. Note mid-dorsal gap in yellow pigment ring, through which oviduct runs and extends into crown. Note demarcation of the lower and upper trunk (arrow). Oviduct emerges onto surface of dorsal trunk at this point. Oviduct is full of oocytes and highly contracted nature of the trunk is evident in zigzag shape of the oviduct on trunk. C. Live holotype (SIO-BIC A7804), a female, in ventral view. Holotype is partially dissected from the gray whale deployed at 385 meters. Root mass (also containing ovarian tissue) has been dissected out of bone on right side and more extends into the bone, away from ovisac. Palps are retracted and curled. Note midventral gap in yellow pigment ring. D. Live adult female in lateral view on same rib bone as in A. There is a gap in yellow pigment ring where oviduct traverses the trunk to become part of the crown. E. Scanning electron micrograph of a female dissected from whale bone deployed at 385 meters. Pinnules of all palps are oriented dorsally. |
