The tubes are attached within rock crevices, and project vertically, near sources of diffuse venting, but probably there is no temperature anomaly in the surrounding water; internal bacteria present probably sulphide oxidizers.

Physical Description

Morphology

Tubes smooth surfaced, straight, hick walled, rigid, tapering to sinuous posterior region 10 to <5 mm diameter. The white obturaculum (15-42 mm long) has a funnelshaped top, with thin anterior rim and smooth inner surface, on a slender stalk elliptical in section. Branchial filaments are parallel to the obturaculum forming lamellae of two types: pale outer sheath lamellae (8-16 pairs) made of adherent filaments without pinnules and red inner lamellae composed of pinnulate filaments.
