FIGURE 6. Osedax knutei n in An inordinate fondness for Osedax (Siboglinidae: Annelida): Fourteen new species of bone worms from California

FIGURE 6. Osedax knutei n. sp., previously Osedax 'nude-palp-E'. A. Preserved female holotype (SIO-BIC A7812) with bone dissected away, but leaving body in place. Roots have ramified laterally parallel to bone surface. Trunk is short and palps, though contracted, are much longer. B. Dwarf male allotype (SIO-BIC A7813) found in tube of holotype. Prominent prototroch and sperm mass anteriorly. Posterior segmented region is slightly swollen with hooked chaetae clearly visible. C. Posterior region of allotype (SIO-BIC A7813), showing paired hooks on one side of segments 2 and 3. D. Live image of paratype (SIO- BIC A7816) partially dissected from bone. Palps are contracted, but still longer than the trunk. Ovisac is visible with root and blood vessel extending further into the bone. E. Live female Osedax knutei n. sp. in turkey bone and spawning oocytes into water. Trunk and lower palp region retracted into bone. Palps and oviduct extend out of the tube and compressed oocytes are visible in oviduct and freshly deposited in water. Specimen was destroyed for sequencing = GB MG262305.
