Weichwarzige Sternschnecke ( Alman )

fornì da wikipedia DE

Die Weichwarzige Sternschnecke (Acanthodoris pilosa) ist eine Art aus der Unterordnung der Nacktkiemer, die zu den Schnecken und somit zum Stamm der Weichtiere gehört. Die Sternschnecke wird wie viele andere Nacktkiemer auch im Volksmund als „Unterwasser-Nacktschnecke“ bezeichnet.

Heimat

Diese Schnecke ist im Mittelmeer und im Atlantik, sowie auch in dessen Seitenmeeren Ärmelkanal, Nordsee und der westlichen Ostsee beheimatet. Dort findet man sie auf Hartböden, Molluskenschalen und Algen. Man sichtet sie von der Gezeitenzone an abwärts.

Aussehen

Die weiße, graue oder auch dunkelbraune Weichwarzige Sternschnecke hat wie viele andere Nacktkiemerschnecken auch einen plumpen und ovalen Körper mit zwei einziehbaren, lamellierten Kopffühlern, den Rhinophoren. Diese Fühler sind von flachen, spitz gezähnten Kragen umrahmt. Der Rücken ist bedeckt mit einer Vielzahl an spitzen Fortsätzen (Papillen), der After wird von einem Kiemenkranz umstanden. Das Tier erreicht eine Länge von fünf Zentimetern.

Lebensweise

Die Schnecke ist ein extremer Nahrungsspezialist – ihr Speiseplan besteht nur aus Moostieren aus den Gattungen Flustrellidra und Alcyondium. Andere Nahrung wird nicht angenommen.

Acanthodoris pilosa ( Anglèis )

fornì da wikipedia EN

Acanthodoris pilosa, the hairy spiny doris,[3] is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Onchidorididae. It is found in shallow water in the northeastern Atlantic Ocean, its range extending from Norway to France, and also both on the eastern coast of Canada and the United States, and the Pacific coast from the Aleutian Islands to Morro Bay, California.[4]

Description

Acanthadoris pilosa grows to a length of about 3 cm (1.2 in), or occasionally as much as 7 cm (2.8 in).[5] It gives the impression of being fluffy because the body is covered with long, fleshy pointed papillae. At the head end are two rhinophores, much larger than the papillae, which house the sensory organs; these typically are bent towards the rear of the animal. At the posterior end there is a distinctive ring of up to nine gills. This sea slug has a uniform colour which may be anything from whitish to pale purplish-brown to darker brown or charcoal grey. Juveniles are often speckled.[5]

Distribution

This species was first described from Norway. It has been reported from the North Atlantic Ocean on both the American and European coasts, and from the Pacific Northwest.[6][4] Specimens from Cobscook Bay, Washington County, Maine and Murles Point, County Donegal, Ireland have been sequenced for the 16S ribosomal RNA, Histone H3 and CO1 genes.[7][8] It is common all round the British Isles in the shallow subtidal zone, at depths down to about 80 m (262 ft).[5]

Reports of this species from Japan[9] must be considered doubtful in the light of recent molecular phylogeny results which show that at least some of the animals from the North Pacific are Acanthodoris atrogriseata.[7]

Ecology

This nudibranch is found on rocks and other hard substrates and feeds on encrusting bryozoans.[4]

Acanthodoris pilosa (лат.) — вид брюхоногих моллюсков из семейства Onchidorididae отряда голожаберных (Nudibranchia)[1].

Описание

Длина тела составляет 5 см. Тело овальной формы белого, серого или тёмно-коричневого цвета, на голове два втягивающихся, слоистых щупальца. Эти щупальца окружают невысокие, заострённые воротнички. Спина покрыта множеством остроконечных выростов, вокруг анального отверстия расположен венец из вторичных жабр.

Питание

Моллюск питается только мшанками родов Flustrellidra и Alcyondium.

Распространение

Вид обитает в Средиземном море и в Атлантике, а также в Ла-Манше, Северном море и западной части Балтийского моря. Он живёт на скалистом грунте, раковинах моллюсков и водорослях. Их можно встретить также ниже зоны приливов и отливов.
