A chemosynthetic weed: the tubeworm Sclerolinum contortum is a bipolar, cosmopolitan species
Background Sclerolinum (Annelida: Siboglinidae) is a genus of small, wiry deep-sea tubeworms that depend on an endosymbiosis with chemosynthetic bacteria for their nutrition, notable for their ability to colonise a multitude of reducing environments. Since the early 2000s, a Sclerolinum population h...
