A bivalve with a brittle, scallop-shaped shell up to 5 cm in length. Both valves are similar in size and shape but are slightly asymmetrical. The animal lives with its left valve facing upwards. The left (upper) valve is brick-red or purplish brown, with white or cream spots and blotches. The right valve is dirty white or pale brick-red near the umbones (depending on size) and down the ribs, and is slightly more convex than the left valve. Each valve has 3-10 (most commonly 5-8) evenly spaced, broad, rounded ribs that increase rapidly in width from the umbone to the margin.
Recorded sparsely around the British Isles but most common off the west coast of Scotland and north of the North Sea.
Pseudamussium peslutrae is recorded from southern Iceland, the Faroes and northern Norway and then south to the Mediterranean and north-west Africa.
Pseudamussium peslutrae is free living, inhabiting muddy mixed sediments offshore to about 300 m in depth.
Pseudamussium peslutrae is variable in shape, colour and structure (sculpture). Juveniles closely resemble Pseudamussium sulcatum but Pseudamussium sulcatum is more coarsely sculptured.
