Overview

Brief Summary

Remarks: Likely two different species of Spiochaetopterus are present at Mid-Atlantic Ridge vent fields. The poor conservation state of the collections does not allow a specific identification; however, the shape of the specialized chaetae is unique.

Physical Description

Morphology

Body long, slender, soft; tubes ringed, horny. Prostomium small, and enfolded by the truncate buccal segment which bears long grooved palps but no tentacular cirri. Fourth chaetiger with a fan of lanceolate chaetae, a large and long spine with a truncated top, slightly cordate and a small aristate spine. Middle region (very damaged) with numerous segments (>15), with two rami, all similar with a bilobed Y-shaped inner part and a small unilobed foliaceous outer part. The neuropodia are unilobed on B1 and bilobed on following segments. The notopodia of the posterior region are erected, slightly inflated posteriorly.
