Abstract: The jumbo squid, Dosidicus gigas, exhibits chromatophore-effected flashing behavior at frequencies of about 3 Hz. In order to characterize this behavior quantitatively and to make it possible to speculate as to its function, videos of D. gigas in its natural environment were taken and analyzed. There is great variability in the consistency of flashing rates among individuals: some stay relatively stable while others fluctuate widely in short spans of time. Videos of two squid encountering one another suggested that squid adjust to their conspecifics' flashing patterns in complex ways. A greater corpus of data will be necessary before specific hypotheses about the function of D. gigas' flashing behavior can be formulated.
