Cover Story: Siboglinidae worms are known to host chemosynthetic endosymbionts in a dedicated trophosome organ. However, little is known about their tube as a potential niche for other microorganisms. In this study, siboglinids sampled from four mud volcanoes in the Gulf of Cádiz (El Cid MV, Bonjardim MV, Al Gacel MV, and Anastasya MV) revealed that the tube was colonized by a thick microbial biofilm. This external biofilm of the tubes was mostly composed of cell-aggregations of methanotrophic bacteria, but other morphotypes such as filamentous, prosthecate, spirillum-like and rod-shaped bacteria were also observed. Yet, these microorganisms seem to influence in the structure and composition of the tube. Thus, siboglinids’ tubes remarkably increase the microbial biomass related to the worms and provide an additional microbial niche in deep-sea ecosystems.View this paper.
