Species Account

Karnekampia sulcata (Müller, 1776)

Pectinoidea : Pectinidae

Tebble name: Chlamys (Chlamys) sulcata (Müller)
Smith & Heppell name: Chlamys sulcata (Müller, 1776)

Notes on Nomenclature

Here previously as Pseudomussium sulcatum.

To size: To 30 mm. Shell Structure: Thin but robust. Equivalve: LV a little more convex than RV. Equilateral: Equilateral. Outline: Subcircular, (umbonal angle about 90°), anterior ears much longer than posterior. Contour: RV with a deep byssal notch, ctenolium well developed.

Sculpture: LV with c.15 primary ribs, these dividing in larger shells towards margins; secondary and tertiary ribs and riblets added with growth to reach about 45 in the largest shells; spacing roughly equal. All ribs with dense, erect scales. Antimarginal microsculpture betwen ribs strong. RV with similar number of ribs but more derived from splitting of primaries rather than addition of secondaries and thus appear clustered. All ribs with scales or nodules. Antimarginal sculpture weak. Posterior ears with 4-5 radial riblets. Colour: Usually uniform, yellow, orange, red. Additional Characters: In some the riblets on the LV coalesce and are raised to form large hollow ribs.

Distribution & Ecology

Ranges from Iceland and northern Norway to the Mediterranean and northwestern Africa. Around the British Isles mostly found at the shelf edge and frequently associated with deep water coral reefs.

Depth Range
Continental Shelf (to 200m)
Continental Margin Zone (200 - 500m)
Bathyal (500 - 2000m)
