Diagnosis Updated genus diagnosis from Rouse et. al. 2018: Diagnosis. Siboglinids with females having a contractile trunk, bulbous ovisac, and branching ‘roots’. A crown of palps usually present, with or without pinnules. Trunk lies within transparent tube emergent from bone surface. Mostly males are dwarfs resembling larvae, exceptionally having a crown, contractile trunk, bulbous testis sac, and branching ‘roots’, as in O. priapus. Crown in females, when present, comprised of cylindrical oviduct plus four palps. Osedax priapus, the only species known to produce adult bone-eating males, has crown with only two palps. No mouth or obvious gut. Cylindrical trunk comprised mostly of longitudinal muscles and glands, with large dorsal and ventral blood vessels present. Oviduct or sperm duct runs dorsally along trunk surface into posterior ovisac, or testis sac. Ovisac or testis sac enclosed by epidermis and trophosome with bacteriocytes, which also extends outwards as vascularized ‘roots’. No chaetae or segmentation apparent in females or bone-eating males. In most species, paedomorphic dwarf males cluster around oviduct in gelatinous tube surrounding trunk of female. The dwarf males possess anterior prototroch and posterior hooked chaetae arranged on two segments. Hooks, lacking rostrum, comprise capitium with curved teeth over subrostral process. Internally, males contain spermatids and sperm anteriorly. [details]Etymology Authors: "From Latin os, bone, and edax, devouring" Gender masculine [details]
