- Recent analyses (Holland & Ghiselin 2008) have unequivocally demonstrated that this species does not possess - as indicated in the 3D models presented here - a siphon tube. Instead, this species is characterized by a so-called siphonal groove, i.e. a groove within the stomach rather than a separate tube. The structure indicated here as a siphon is in fact a haemal structure adjoining the stomach, the so-called inner marginal sinus.
