Tebble name: n/a
Smith & Heppell name: n/a

To size: To 10 mm. Shell Structure: Fragile, semi-transparent. Equivalve: Equivalve. Equilateral: Equilateral. Tumidity: Both valves weakly convex. Outline: Disc subcircular, slightly longer than high. Anterior ears slightly longer than posterior ears and more demarcated from disc. Byssal notch small, ctenolium absent.

Sculpture: Both valves smooth except for weak and sparse anastomosing raised radial lines over umbonal area of LV. Colour: White, semitransparent.

Distribution & Ecology

Continental Margin Zone (200 - 500m)
Bathyal (500 - 2000m)

Key Features & Similar Species

Very similar to S. similis but that species has no microsculpture on either valve and is frequently patterned. S. greenlandicus has much stronger sculpture, reaches a greater size and is restricted to arctic and subarctic waters.
