Taxonomy
- Kingdom: Animalia
- Phylum: Annelida
- Class: Polychaeta
- Order: Phyllodocida
- Family: Polynoidae
- Genus: Eunoe Grube, 1850
- Species: Eunoe anderssoni (Pettibone, 1949)
Authority
The species Eunoe anderssoni is recorded in the World Register of Marine Species (WoRMS) as a valid taxon, with the original description attributed to Pettibone in 1949.
Description
Members of the genus Eunoe are commonly referred to as scale worms because of the presence of dorsal elytra (scale‑like plates). While a detailed species‑specific description for E. anderssoni is not widely published, it can be inferred that the organism possesses the general morphological traits of its genus: an elongated, dorsoventrally flattened body composed of multiple thoracic and abdominal segments, a pair of antennae on the prostomium, and a series of paired elytra covering the dorsum. Typical Eunoe species have 15 pairs of elytra and range from 30 to 70 body segments.
Distribution and Habitat
Eunoe anderssoni has been reported from marine environments of the Southern Ocean, particularly in Antarctic and sub‑Antarctic waters. Specimens have been collected from soft‑sediment habitats at depths ranging from the shallow subtidal zone to several hundred meters, consistent with the benthic lifestyle of many polynoid polychaetes.
Ecology
Like other scale worms, E. anderssoni is predatory or scavenging, feeding on small invertebrates and organic detritus on or within the substrate. The species is presumed to be a component of the benthic community, contributing to the trophic dynamics of Antarctic marine ecosystems.
