In reducing sediments; found buried 20-30 cm deep in pale-coloured coarse sediment at the base of an isolated large siboglinid tube in a seep area at the edge of a hydrothermal vent. Known from vents only. Gills very likely harbouring chemosynthetic symbiosis. Lecitrotrophic development, most probably no, or extremely short, free swimming larval phase. Larval shell (no separate protoconch I & II) 1.35 mm long and 0.68 mm high.
