Neopolynoe acanellae is a scale worm known from the North Atlantic Ocean at depths about 400 to 2000 m. [2] [3]
Neopolynoe acanellae has up to 72 segments with 15 pairs of elytra that bear marginal fringe of papillae but no color patterning. Lateral antennae are positioned ventrally on the prostomium, directly beneath the median antenna ceratophore and almost obscured in dorsal view. The notochaetae are about as thick as neurochaetae and only possess simple tips. [2] [4]
Neopolynoe acanellae has a commensal relationship with host corals of the genus Anthomastus and Acanella, as well as with sponges. [5]
Polynoidae is a family of marine Polychaete worms known as "scale worms" due to the scale-like elytra on the dorsal surface. Almost 900 species are currently recognised belonging to 9 subfamilies and 167 genera. They are active hunters, but generally dwell in protected environments such as under stones. The group is widely distributed from shallow intertidal waters to hadal trenches. They are the most diverse group of polychaetes in terms of genus number and second most diverse in terms of species number which is almost 8% of all segmented worm species.
Harmothoe is a genus of marine Polychaete worms belonging to the family Polynoidae. Species of Harmothoe are found world-wide to depths of at least 5,000 m but are more common in shallower water.
Adyte hyalina is a species of marine annelids in the family Polynoidae and the only accepted species in the genus Adyte. Adyte hyalina occurs in the North-east Atlantic Ocean and Mediterranean Sea, at depths down to about 150 metres.
