One of the more unusual adaptations found at these "whale-fall" communities is in polychaete worms of the genus Osedax (Annelida, Siboglinidae), which use root tissues containing bacterial symbionts to derive nutrition through the excavation of the bones (Rouse et al, 2004).

In the marine polychaete family Siboglinidae, a unique symbiont-housing organ termed the trophosome has evolved.

In the small polychaete family Siboglinidae Caullerery, 1914 (McHugh, 1997; Rouse and Fauchald, 1997; Rouse et al., 2004), consisting of Vestimentifera, Sclerolinum, Osedax, and Frenulata, all representatives--with the exception of Osedax dwarf males (Rouse et al., 2004)--apparently have a symbiont-housing organ, called a trophosome, originating from different germ lines.

The best known of these symbioses is the giant vent tubeworm Riftia pachyptila Jones, 1981 (hereafter referred to as Riftia), a monospecific genus within the family Siboglinidae (Rouse, 2001).

Despite this obligate association, there is no evidence for vertical transmission of symbionts from parents to offspring in Siboglinidae. For those hosts examined to date (mainly vestimentiferans), no bacteria have been found in the gonadal tissues, sperm, eggs, or early-stage larvae (Cavanaugh et al., 1981; Cary et al., 1989, 1993), and phylogenies of the host and the symbiont are not congruent (Feldman et al., 1997; Di Meo et al., 2000; Nelson and Fisher, 2000).
