This dataset is a scanned copy of ANARE Research Notes 3, which describe the Pelagic Polychaetes of the Southern Ocean. It lists all the known species and with illustrated diagrams provides a guide to their taxonomic identification.
Taken from the abstract:
The pelagic polychaetes of the Southern Ocean include Vanadis antarctica (McIntosh), V. longissima (Levinsen), Rhynchonerella bongraini (Gravier), R. petersii (Langerhans), Tomopteris carpenteri (Quatrefages), T. cavallii (Rosa), T. ligulata (Rosa), T. planktonis (Apstein), T. septentrionalis (Steenstrup), Typhloscolex mulleri (Busch), Sagitella kowalevskii (Wagner), Travisiopsis coniceps (Chamberlin), Tr. lobifera (Levinsen), Tr. levinseni (Southern), Tr. lanceolata (Southern), Phalacrophorus pictus (Greeff), Pelagobia longicirrata (Greef) and Maupasia caeca (Viguier).
The diagnostic characters, geographical and bathymetric distribution and synonymy of each of these polychaetes are given together with illustrations and distribution maps. A key is given for the identification of these polychaetes and species found in waters adjacent to the Southern Ocean.
Polychaetes can be divided into two groups; sedentary forms, and errant of free-moving forms including some strictly pelagic species. Although the great majority of adult polychaetes are benthonic, the larvae of most polychaetes are planktonic and the sexual stages of certain families such as the Sylidae and Nereidae are found at night in tow-netting over shallow water.
