Zierliche Asselspinne ( German )

provided by wikipedia DE

Die Zierliche Asselspinne (Nymphon rubrum) ist eine Art aus der Klasse der Asselspinnen.

Merkmale

Die Tiere haben eine Körperlänge von maximal 10 Millimetern, die Beine sind zusätzlich bis zu 25 Millimeter lang. Die Pedipalpen und Cheliceren sind deutlich ausgebildet. Der Eiträger (Oviger) ist sehr dünn, aber bei beiden Geschlechtern ausgebildet.[1]

Vorkommen und Lebensweise

Die Zierliche Asselspinne tritt an fast allen Meeresküsten Europas auf und besiedelt Polypenstöcke, Moostierkolonien oder Algen in Küstennähe. Die Art ernährt sich vor allem von Polypenstöcken, an denen sie mit ihren Cheliceren einzelne Polypen packen und aussaugen.[1]

Nymphon brevirostre

provided by wikipedia EN

Nymphon brevirostre is a species of sea spider first described by George Hodge in 1863.[1] The species highly resembles other members of the genus Nymphon (e.g. N. rubrum), and species identification from morphological traits alone is therefore a complex task.[2]

Morphology

Early life stage morphology

White, translucent or reddish, occasionally with violet bands. Slender body (2.5-3.0 mm) and legs that are three and a half times as long. The proboscis is relatively short. The abdomen is thick, and the thoracic segments are broader than long. The palps have five joints. The propodus is longer than the tarsus, which is covered with numerous short spines and three longer ones near the heel.[2]

Later life stage morphology

Morphological characteristics very similar to earlier life stages. Reddish or white. Smooth and slender body (4-5mm) and legs four times this. The cephalon is broad, and the abdomen is relatively short. Male specimens carry the eggs on specially designed appendages (2).

Habitat

The species inhabits the littoral and sublittoral zone to a depth of 60m and occurs amongst hydroids. Its distribution ranges from the Arctic to at least south of Great Britain, and is widely distributed in both The North Sea and The Baltic Sea (2, 3). In The Baltic Sea, this species has been found around Elsinor in Denmark in depths of ~37m amongst dense populations of the hydroids Abietinaria abietina, Alcyonium digitatum and various other hydroids.[3]

Diet

Feeds on e.g. coelenterate species (2,3). The species is able to detect the chemical cues of different hydroids such as Dynamena pumila, Laomeda loveni, Tubularia larynx and Alcyonium digitatum (5).

Nymphon brevirostre ( French )

provided by wikipedia FR

Nymphon brevisrostre est une espèce de pycnogonide de la famille des Nymphonidés.

Description

Il est très proche du Nymphon grêle, bien que légèrement plus petit. Il s'en différencie par une trompe un peu plus courte, et surtout par le dernier article des palpes du céphalon (pédipalpe) qui est bien plus long que l'article précédent.

Répartition et habitat

On retrouve Nymphon brevirostre dans les eaux froides européennes entre la Norvège arctique et les côtes bretonnes. Il est très présent sur les côtes britanniques.
