Description
Neopolynoe paradoxa has up to 60 segments with 15 pairs of elytra that bear marginal fringe of papillae. Lateral antennae are positioned ventrally on the prostomium, directly beneath the median antenna ceratophore and almost obscured in dorsal view. The notochaetae are distinctly thicker than the neurochaetae and only possess simple tips.Jirkov, I.A. (2001). [Polychaeta of the Arctic Ocean] (In Russian) Polikhety severnogo Ledovitogo Okeana.
