From: The spatial pattern of bioluminescent flashes in the polychaete Eusyllis blomstrandi (Annelida)
A flash series emitted by a posterior fragment of Eusyllis blomstrandi following a series of mechanical shocks to the support (identical material as in Figs. 4, 5). The flash series was rhythmic but asynchronous to the shocks. The flashes labelled by a, b, and c are seen as close-ups in Fig. 5. Coordinates and symbols as in Fig. 5.
