Ridges forming the concentric sculpture on the shells of laboratory-grown specimens of Pecten diegensis Dall show daily periodicity. Missing growth lines account for all scatter in the data, so that the maximum, not the average, line count is most representative. The variation in spacing between growth lines can be correlated among specimens.
