Harmothoe aspera has been recorded in surveys off the Strait of Georgia, the Skagerrak, and the Barents, Mediterranean and Japanese sea. The recorded depth ranged from circa 48 m to circa 1500 m. This is the first report of H. aspera in the Dutch Exclusive Economic Zone (EEZ), and the first report in a depth range between 15 and 20 m.
Polynoidae (scale worms) is a highly diverse family of polychaetes including more than 700 species (Martin and Britayev 1998). Members of this family are easily recognizable by their dorsal elytra. Polynoidae are mainly considered to be free-living carnivorous-polyphagous (Fauchald and Jumars 1979). Their life strategies and known diets are highly diverse, with more than 20% being symbiotic species. Polynoidae feed on and interact with all kinds of prey including small crustaceans, echinoderms, sponges, gastropods, hydroids and other polychaetes (Fauchald and Jumars 1979).

The first record of H. aspera was made by Hansen (1879) during the Norwegian North-Atlantic Expedition at station 48 (Lat, 64° 36′ N. Long 10° 22′ W) near the coast of Iceland. The recorded depth was 547 m. The habitat in which H. aspera was found was characterized as dark grey porous clay which contained granite, a few quartz pebbles and a few calcareous shells. The bottom temperature was recorded at −0,3 degrees Celsius (Schmelk, 1882). This article is the first report of H. aspera in the Dutch Exclusive Economic Zone (EEZ) and the first report for H. aspera in a depth range between 15 and 20 m.
Order: Phyllodocida Dales, 1962.
Family: Polynoidae Kinberg, 1856.
Genus: Harmothoe Kinberg, 1856.
Species: Harmothoe aspera (Hansen, 1879).
The two specimens of H. aspera have the following specifications. Both were incomplete and damaged at their posterior end, had no sexual products and had most of their elytra missing. Specimen one measured 3.5 mm long with 19 segments. Segment 18–19 were damaged and only 3 elytra remained (reference collection Rijkswaterstaat). Specimen two measured 2.6 mm long with 15 segments. The left half of segment 14 was missing with 1 elytron left (reference collection Rijkswaterstaat).
The presence of large pyramid shaped macrotubercles, as described by Barnich and Fiege (2000), is a clear key characteristic. Nonetheless, H. aspera can be confused with three other species: Harmothoe globifera, Harmothoe bellani and Harmothoe lagiscoides serrata. H. globifera differs by having much longer marginal papillae on the outer lateral margin of their elytra and the macro- and microtubercles are rounded, globose and covered with small nodular papillae. H. bellani differs by having thorn-shaped microtubercles and no macrotubercles. H. lagiscoides serratai differs by having slender and thorn-shaped macrotubercles (Barnich and Fiege 2000).
The L15-A platform has a steel jacket foundation which is standing in waters 22 m deep with a sandy bottom that is locally covered with rock dump to prevent scouring of the seabed. The two H. aspera specimens were found in fouling communities growing on steel in vertical orientation. The community at the sampled depths was dominated by Metridium senile and Tubulariidae covered with Jassa herdmani turf. In total, 60 benthic species where present in the 8 samples obtained at these depths, with representatives from Annelida (15 spp), Arthropoda (20 spp), Bryozoa (5 spp), Cnidaria (3 spp), Echinodermata (3 spp), Mollusca (10 spp) and Porifera (4 spp). H. aspera was observed close to the seabed, but was not present in samples taken from the rocks at the bottom of the platform.
The presence of H. aspera of the coast of Vlieland represents its first ever record in the Dutch EEZ. Since its first discovery in 1879 information on H. aspera has been scarce with only a few records since the 1970’s.
The original description from Hansen (1879) contains habitat information on bottom materials, depth and temperature. Besides this account no further descriptions can be found within other records that give information about the habitat of H. aspera. There are also no recorded descriptions about its lifecycle or reproduction. There are only species records containing a year and sometimes a depth is listed. Harmothoe aspera is found in different seas all over the world. In 1876–1878 it has been recorded during the Norwegian North-Atlantic Expedition (Hansen 1879), in 1973 it was recorded in the Strait of Georgia on a 52 year old telephone cable (Levings and McDaniel 1974), in the 1990’s it was found for the first time in the Western Mediterranean (Barnich and Fiege 2000) and around 2006–2008 it was recorded in the Barents Sea (Anisimova et al. 2010). It appears that H. aspera is mostly observed at a depth range between 200 and 300 m, although it has also been observed at shallower depths of 48 m in the waters of Sweden. It must be noted that our depth record (15–20 m) is the shallowest depth record for H. aspera to date.
H. aspera remains a species of which very little is known. The observation of H. aspera on artificial hard substrate in the North Sea emphasizes the importance of investigations of benthic communities on these structures. This finding increases the diversity of Polynoidae found on artificial hard substrates.
The work reported in this publication was funded through the Wageningen UR TripleP@Sea Innovation program (J.C., KB-14-007) and by the Dutch Department of Economic Affairs (J.C., KB-24-16), the Nederlandse Aardolie Maatschappij BV, Wintershall Holding GmbH and Energiebeheer Nederland B.V. and the INSITE North Sea fund via the RECON project.
ENGIE Exploration & Production Nederland B.V. allowed and facilitated us to sample their installations and we are especially grateful to Ed Schmidt, Nathalie Kaarls, Ulf Sjöqvist, Maico Vrijenhoeff, Ben Waardenburg and Kees van Braak for their help arranging this cooperation.
Further help was provided by Ruth Barnich who confirmed the identification.
