Three-dimensional surface scans of the left and right valves of a representative scallop, with the landmarks and semilandmarks shown. Five landmarks are numbered and represented by large dots and the semilandmarks are shown as small dots. Landmark 1: ventro-posterior auricle, 2: dorsoposterior auricle, 3: umbo, 4: dorsoanterior auricle, 5: ventroanterior auricle. In life, the left valve (‘upper’) is usually oriented upwards, with the right valve (‘lower’) against the substrate, hence the visible colour differences shown here
