|Habitat:||Intertidal. Rocky shore. Bays and sheltered beaches. Infaunal. Epifaunal. Depth range: 0-2 (m). Salinity regime: Harbour-like variation. Microhabitat: Muddy crevices. Tube: None, but galleries (burrow track) in sediment.|
|Occurrence:|| Common. Density: 400 (m2).
Distribution in NZ: New Zealand wide.
|Feeding guild:||Surface omnivore.|
|Diagnosis:||Genus Marphysa in Family Eunicidae.
Marphysawith branchiae beginning from chaetiger 25 or further back, with 1 to 4 filaments. Body section flattened dorso-ventrally after the first few segments. Pale subacicular hooks in post body have distinctly bidentate tips with small hood. Supra-acicular chaetae are capillaries with some delicate inconspicuous comb-tipped chaetae present. Subacicular chaetae are compound capillaries and falcigers. Colour: Grey body with red branchiae. Maximum size: 400 mm total length, 7 mm body width.
|Notable aspect:||Presence of compound capillaries.|
|Comparisons:||Other shore Marphysa such as M. capensis may appear quite similar and examination of chaetal types will be needed to distinguish them.|
|Taxonomy:||The purported four valid New Zealand Marphysa species need to be reviewed again.|
|Distribution:||Endemic. Also reported for South Africa|
|Biology:||Little is known. Note that Morton & Miller 1968 may be including more than one species in their comments using this name.|
