Eunice is a genus in the polychaete family Eunicidae. Individuals grow to a length of between 0.5 and 300 cm (0.20 and 118.11 in). [1] . Their bodies have multiple segments. They have two eyes and five tentacles. They have well-developed sense organs and relatively large brains.

Eunicidae is a family of marine polychaetes (bristle worms). The family comprises marine annelids distributed in diverse benthic habitats across Oceania, Europe, South America, North America, Asia and Africa. [1] .

Eunice is the largest and most poorly defined genus in Eunicidae. It has traditionally been subdivided in taxonomically informal groups based on the colour and dentition of subacicular hooks, and branchial distribution.

The genus includes around 250 valid species (Read and Fauchald 2021). However, this number is likely to be an over-estimate because some species of the revalidated genera Leodice and Nicidion are still formally classified within Eunice (Zanol et al. 2021).

The genus Eunice has been widely reported in all kinds of marine environment. A total of 286 names have been applied to taxa originally described in, or subsequently referred to, the genus.

…examples of genera: Palola (palolo), Eunice, Stauronereis, Lumbineris, Onuphis. Order Orbiniida Sedentary; head pointed or rounded without appendages; proboscis eversible and unarmed; body divided into distinct thorax and abdomen; gills arise dorsally from thoracic region;

This paper explores the phylogenetic relationships within the genus Eunice, a diverse group of polychaete worms in the family Eunicidae. The analysis reveals challenges in the taxonomy of Eunice due to poor ontogenetic understanding and significant intraspecific variation, leading to historical naming issues within the genus.

Eunice pennata is a species of polychaete worm within the family Eunicidae. The species has a cosmopolitan distribution, mainly being found in subtropical to polar regions of oceans at depths of 813 to 1064 meters. [1][2] Areas the species has the most observations include waters around Scandinavia, New England, southern Argentina and Chile ...
