When addressing the question of homology of the trophosome in Siboglinidae, an evaluation and comparison of body regions among all members of this taxon is inevitable.
In that case, the trophosome would not serve as a morphological character unifying the family Siboglinidae, nor would the nonfunctional, occluded gut (Rouse, 2001) be a synapomorphic character of this taxon.
The phylogenetic position of Siboglinidae (Annelida) inferred from 18S rRNA, 28S rRNA and morphological data.
Actual distribution of bacteriocytes in the trophosome of a beard worm (Oligobrachia mashikoi, Siboglinidae, Annelida): clarification using whole mount in situ hybridization.
The spermatozoa of Siboglinidae share a similar ground plan: they are filiform cells formed, in sequence, by a helical acrosome, an elongated coiled nucleus surrounded by a variable number of helical mitochondria, and by a long and simple flagellum (Rouse, 1999).
