The Smooth Artemis ( Dosinia lupinus ), also called Helle Artemis , is a type of mussel from the order of the Venerida .
features
The rounded, elliptical case , which has the same flaps, measures around 3.8 cm in diameter. The vertical axis is slightly larger than the horizontal axis. It's relatively flat, i.e. H. the two valves are moderately arched outwards (inflated). It is slightly unequal, the vertebrae sit a little in front of the center line (based on the length of the case). The vertebrae are bent forward (prosogyr). The lunula is clearly separated with a radial back, but quite short. The lock has three cardinal teeth in both flaps. In the left valve there is also a small lateral tooth in front of the first cardinal tooth. The deeply sunken ligament extends over about half the length of the posterior dorsal margin. The inner edge of the case is smooth. The surface line shows a deep and narrow bay. The siphons are quite long and grown together.
The shell is strong. The surface shows only fine concentric ribs and streaking growth. The color of the outside varies from pale yellow to off-white. Occasionally beige radial rays emanate from the vertebrae. The periostracum is a thin pale yellow coating.
Similar species
The Artemis Shell ( Dosinia exoleta ) is slightly more rounded in outline and also slightly larger than the Smooth Artemis. The surface of the smooth Artemis case is glossy, whereas the surface of the Artemis shell is rather matte. The outside is more ribbed and the ligament is slightly shorter.
Geographical distribution, habitat and way of life
The smooth Artemis occurs in the eastern Atlantic from Norway to West Africa, including the North Sea and the Mediterranean.
It lives buried in sandy-silty, coarse-sanded to gravelly shell-fracture substrates from the tidal range to about 270 meters water depth.
Taxonomy
The taxon was first described by Carl von Linné in 1758 as Venus lupinus . It is now generally accepted as belonging to the genus Dosinia Scopoli, 1777.
