FIGURE 2. Osedax sigridae n in An inordinate fondness for Osedax (Siboglinidae: Annelida): Fourteen new species of bone worms from California

FIGURE 2. Osedax sigridae n. sp., previously Osedax 'green palp'. A. View of cut surface of a cow femur deployed at 1820 meters in Monterey Canyon. Uncut surface of the bone has been heavily colonized by Osedax sigridae n. sp. Note greenishyellow color of the palps. B. Osedax sigridae n. sp. specimens in A. penetrated through outer surface of the cow bone and then expanded into the area beneath. This allowed for the whole outer layer of outer bone, and the Osedax, to be peeled away. Posterior ends (ovisacs) of multiple individuals are shown here. No major root structures extend from the ovisacs. C. Paratype of Osedax sigridae n. sp. (SIO-BIC A7810) with some bone surrounding the trunk. Oviduct is visible and pinnules of all four palps are oriented dorsally. D. Dorso-lateral view of holotype of Osedax sigridae n. sp. (SIO-BIC A7809) dissected from bone. Oviduct is not visible as it lies among the palps, which have pinnules oriented dorsally. Note greenish hue of palps. Green tissue surrounding part of the ovisac.
