Tebble name: n/a
Smith & Heppell name: Decipula tenella (Lovén, 1846)

To size: To 6 mm. Shell Structure: Thin. Equivalve: Equivalve. Equilateral: Inequilateral, beaks behind the midline about 2/3 of length from anterior. Tumidity: Moderately convex. Outline: Sub-elliptical expanded anterior ventrally; anterior dorsal margin long curving to curved posterior ventral margin, ventral weakly curving to more narrowly rounded posterior.

Sculpture: Almost smooth with fine concentric lines and stronger growth stops, faint radial striations usually present. Margin: Inner margin smooth. Ligament: Mostly internal set on a shallow resilifer behind the beaks; angle between resilifer and margin at least 90 degrees. Hinge: LV with a very small laminar tooth in front of the beak; RV with a corresponding socket. Pallial Musculature: Pallial line entire. Periostracum: Periostracum thin, shiny. Colour: Shell white often with a ferruginous deposit over the umbos.

Distribution & Ecology

Associated with the burrowing urchin Brissopsis. Currently known from only a few records from the west coast of Scotland, from the northern North Sea and most recently from west of the Scilly Isles.
Van Aartsen (1997) states the distribution of this species as Atlantic, Lusitanian and Boreal. Probably widely confused with
M. ferruginosa and therefore under recorded as the urchin has a wider range.

Depth Range
Continental Shelf (to 200m)
