Chlamys rubida
species of mollusc
Chlamys rubida is a species of bivalve mollusc in the family Pectinidae found on the west coast of North America from the Gulf of Alaska to San Diego, California.
Description
The pink scallop has two convex valves joined by a hinge joint and grows to a diameter of about 6 centimetres (2.4 in). Each valve has an umbo or knoblike protuberance from which 20 to 30 shallow ridges radiate to the margin at the other side of the shell. The left valve is usually uppermost as it lies on the seabed and is some shade of red intermixed with white streaks. The annual growth rings can be seen and there is concentric sculpturing parallel to the margin, often in a different shade of pink. The lower valve is either a paler shade of pink or dull white. There is a large auricle or flap on one side of the umbo. When the animal is feeding, it holds the valves apart and the mantle becomes visible, fringed with short tentacles and with a ring of tiny eyes near the margin of each valve.
The pink scallop can be distinguished from its close relative the spiny scallop (Chlamys hastata) by the valves being rather more rounded and by the lack of spines on the ribs which gives it a smooth texture. The glossy white interior of the shell does not have the purplish markings that are sometimes present in the spiny scallop.
The public source identifies “Chlamys rubida” as species of mollusc. This brief keeps that definition visible, then builds a research path around Chlamys, rubida and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Chlamys rubida”, the useful work is to connect “species of mollusc” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q3016144. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
