Gattyana cirrhosa (Pallas 1766)

Gattyana cirrhosa ( anglais )

fourni par wikipedia EN

Gattyana cirrhosa is a scale worm known from widespread locations in the North Atlantic, Arctic, and northwestern Pacific oceans, from the intertidal zone to depths of at least 1,200 m (3,900 ft).[2][3]

Description

Gattyana cirrhosa is a short-bodied worm with 38 segments and 15 pairs of elytra, which bear a marginal fringe of papillae and are a rich brassy-orange colour. The lateral antennae are positioned ventrally on the prostomium, directly beneath the median antenna. Notochaetae are about as thick as or thinner than the neurochaetae.[2][4]

Biology and ecology

Gattyana cirrhosa has a commensal relationship with chaetopterid, terebellid, and pectinariid polychaete worms, living within the tubes they construct. However, it is also a free-living taxon.

Gekroesde zeerups ( néerlandais ; flamand )

fourni par wikipedia NL

De gekroesde zeerups (Gattyana cirrhosa) is een borstelworm uit de familie Polynoidae. Het lichaam van de worm bestaat uit een kop, een cilindrisch, gesegmenteerd lichaam en een staartstukje. De kop bestaat uit een prostomium (gedeelte voor de mondopening) en een peristomium (gedeelte rond de mond) en draagt gepaarde aanhangsels (palpen, antennen en cirri).

Gattyana cirrhosa werd in 1766 voor het eerst wetenschappelijk beschreven door Pallas.

Gattyana cirrhosa (лат.) — вид морских многощетинковых червей семейства Polynoidae из отряда Phyllodocida[2].

Описание

Встречаются на глубинах от литоральных илистых грунтов до 1000 м в водах Северного Ледовитого океана, северной части Тихого океана и северной Атлантики, включая проливы Скагеррак и Каттегат и Северное море. Длина тела до 50 мм, включает до 38 сегментов[3]. На простомиуме три пары антенн (Polynoinae) и глаза на омматофорах. Перистомальные усики с циррофорами. Простомиум разделён медиальным желобком на две части. Параподии двуветвистые. Все щетинки (сеты) простые [2][4][5]. Часто обнаруживается в пустых трубках других полихет например, Amphitrite, Chaetopterus, Thelepus или вместе с мшанками Melobesia и Amphihelia. Один их самых обычных для северных морей вид полихет семейства Polynoidae[6].

Biology ( anglais )

fourni par World Register of Marine Species
Breeding probably takes place in spring (March-June) and the larvae develop in the water column. The species spawns several times during its life. It can reach an age of at least 4-5 years. In the subtidal parts of the area, G. cirrhosa is almost exclusively found in the tubes of the polychaete Chaetopterus variopedatus. Other studies have recorded the species from (empty) tubes of other polychaetes such as Lagis koreni and Amphitrite johnstoni, and in Arenicola burrows. G. cirrosa, like all polynoids, is considered a predatory carnivore. Small crustaceans, echinoderms, polychaetes, gastropods, sponges and hydroids have been mentioned as prey items. (Hartmann-Schröder, 1971; Wolff, 1973; Curtis, 1977; Fauchald & Jumars, 1979; Hayward & Ryland, 1990).

This species is very abundant at the Oyster Ground, where it forms a substantial part of the infaunal biomass. G. cirrhosa also occurs in the Delta area (Grevelingenmeer, Ooster- and Westerschelde). The species is (almost) absent from the Southern Bight and the Wadden Sea.

Morphology ( anglais )

fourni par World Register of Marine Species
This species has a flattened body that is oval in outline. lt is composed of up to 38 segrnents and reaches 40 mm in length. The dorsal surface is covered with fifteen pairs of soft scales (elytra). These elytra are covered with minute spines and have a fringe of papillae along the outer edge. The head bears four eyes, one median and two lateral antennae. The elytra have a distinct dark spot in the centre (Hartmann-Schröder, 1971; Hayward & Ryland, 1990).
