New records of the deep-sea Nogrobs grimaldii (Serpulidae: Annelida).
Contents
Abstract
The poorly-known serpulid Nogrobs grimaldii was originally described based on specimens collected from off Azores at depths of 1846–1900 m. Its adults are characterized by thick pinnulated opercular peduncle and unusual free (unattached) quadrangular tube coiled into a flat spiral. Here we review and re-identify published material and report new records of this enigmatic deep-water serpulid.
