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.

All chaetopterids have highly modified body regions that enable them to strain water through mucous bags. All chaetopterids secrete the tube from glands located on the ventral side of the anterior body region.

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.
