FIGURE 17. Osedax randyi n. sp., previously Osedax 'white collar'. A. Micrograph of live holotype (SIO-BIC A7845), female in lateral view, removed from its tube and showing crown, trunk and part of ovisac. Note midventral gap in white pigment ring. B. Dorsal view of live specimen (paratype SIO-BIC A7847) showing white pigmented ring anteriorly with a dorsal gap where oviduct runs through it. Note pinnules of all palps oriented dorsally and oviduct lying between dorsalmost pair of palps. C. Differential interference micrograph of a solitary male dissected from tube of paratype (SIO-BIC A7847). Some hooks are visible in expanded posterior region. A large mass of mature sperm is visible in mid-body and extending into head, though there are a few obvious spermatids. D. Transverse section (7 µm) of paratype (SIO-BIC A7847), through crown showing pinnules of all palps oriented dorsally and oviduct lying between dorsalmost pair of palps. E. Transverse section (7 µm) through the trunk of paratype (SIO-BIC A7847) showing extensive musculature and glands. Prominent dorsal and ventral blood vessels are also visible.
