Notomastus latericeus est une espèce de vers annélides polychètes vivant dans les fonds marins sableux et les vasières. Il atteint 30 cm de long.
Description
Son corps tubiforme, rouge à jaunâtre, est divisé en 100 à 150 segments.
La région antérieure est pourpre à rouge foncé, l'autre partie étant jaunâtre ou plus claire.
De fines soies (poils) de nature chitineuse sont visibles sur son épiderme.
Des paires de pores génitales s'ouvrent sur la face dorsale antérieure de nombreux segments de la région postérieure.
La partie antérieure de son corps (pygidium) se termine en éléments membraneux.
Dans les eaux moins oxygénées, il respire grâce à des branchies plus ou moins formées, simples et formées d'extensions de sa muqueuse.
Habitat
Il vit sur et dans les fonds plutôt sableux des zones peu profondes à moyennement profondes du plateau continental.
Il est parfois également observé dans les algues marines.

Biology

Pelagic larvae have been found in December, February and April, whereas settling has been observed in August-October. The settling larvae prefer mud and sand above clean shell gravel and are not very tolerant to low salinities. N. latericeus is tubicolous as a juvenile, but free-living when adult. Adult specimens build partially spiralled burrows that maintain integrity for some time after construction, but lack a distinct wall structure. Capitellids are mentioned to be non-selective deposit feeders, although N. latericeus may prove to be more selective as suggested by its gut contents. The species is recorded living as a commensal with the entoproct Loxosoma singulare (Hartmann-Schröder, 1971; Wolff, 1973; Fauchald & Jumars, 1979).

This species is quite common at the Oyster Ground. N. latericeus also occurs at a few locations in the south-western part of the Southern Bight, near the coast and in the marine part of the Delta area.

Notomastus latericeus has a relatively low frequency of occurrence, but is found across the entire Belgian part of the North Sea. The species is almost completely (1976-1986 period) or even completely absent (1994-2001 period) in the eastern coastal zone only. In the 1976-1986 period densities remained below 100 ind./m2 whereas densities up to approximately 600 ind./m2 were recorded in the 1994-2001 period.

Habitat
provided by World Register of Marine Species
Notomastus latericeus has no clear preference for a specific median grain size: the habitat preference appears to be mainly determined by the mud content. Sediments with a mud content of 0 to 50% are suitable for N. latericeus, but the species displays a preference for sediments with a mud content of 10-30% (relative occurrence: > 50%).

Morphology
provided by World Register of Marine Species
Like most members of the Capitellidae this is a species with a simple, smooth body, lacking any appendages other than short chaetae. The head is short, triangular and smooth. The species has an eversible sac-like pharynx. The body is relatively long, up to 150 mm, and made up of 150 segments, which are of two types and divided over two body regions. The anterior region is relatively thick, cylindrical and purple or dark red. The tail region is more slender and bright red or yellowish (Hartmann-Schröder, 1971; Hayward & Ryland, 1990).
