Eunoe (animal)

Eunoe is a genus of marine annelids in the family Polynoidae (scale worms). The genus includes 48 species which are found world-wide, mostly from depths of 50 m or more.

Description
Body dorsoventrally flattened, short, with up to 50 segments; dorsum more or less covered by elytra or short posterior region uncovered. Fifteen pairs of elytra on segments 2, 4, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 26, 29, and 32. Prostomium with or without distinct cephalic peaks and three antennae; lateral antennae inserted ventrally to median antenna. Anterior pair of eyes dorsolateral at widest part of prostomium, posterior pair dorsal near hind margin. Parapodia with elongate acicular lobes with both acicula penetrating epidermis; neuropodia with a supra-acicular process. Notochaetae stout with distinct rows of spines and blunt tip. Neurochaetae more numerous and more slender, with distinct rows of spines distally and exclusively unidentate tips.

The genus was described in 1865, with a modern redescription in Barnich & Fiege (2010). Eunoe is one of a number of related genera with 15 pairs of elytra.
