Leucia violacea is a species of polychaete worm, commonly known as a "scale worm", in the family Polynoidae. This species occurs in the northeastern Atlantic Ocean.

Description

The body has 42 segments which are concealed by sixteen pairs of elytra in two rows. The length of this worm is about 42 mm (1.7 in) and the width 9 mm (0.4 in). The prostomium has two lobes with a pair of acute anterior projections, a median antenna and a pair of lateral antennae inserted ventrally (beneath prostomium and median antenna), a pair of smooth palps and two pairs of eyes. The body is red to brown above and white beneath, and the scales are pink to violet. [2] It can be distinguished from Leucia nivea , the only other member of the genus, by the microtubercles on the scales being all conical while the macrotubercles are scattered and indistinct. Notochaetae distinctly thicker than neurochaetae. Unidentate and bidentate neurochaetae are present. [2]

Taxonomy

This species was first described by the Norwegian zoologist Vilhelm Storm in 1879 as Laenilla violacea but was later transferred to the genus Harmothoe . During a revision of this genus in 2009, H. violacea was reassigned to Leucia violacea on the basis that members of Harmothoe have fifteen pairs of scales while members of Leucia have sixteen. [2]

Distribution and habitat

This species occurs in the northeastern Atlantic Ocean, its range extending from Norway to the Bay of Biscay at depths between 30 and 1,262 m (100 and 4,100 ft). It is found on hard substrates, often associated with cold water corals such as Lophelia pertusa and Madrepora oculata . [2]

Parapodium

In invertebrates, the term parapodium refers to lateral outgrowths or protrusions from the body. Parapodia are predominantly found in annelids, where they are paired, un-jointed lateral outgrowths that bear the chaetae. In several groups of sea snails and sea slugs, 'parapodium' refers to lateral fleshy protrusions.

Polynoidae Family of annelids

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.
