The diurnal and nocturnal valve gaping behavior of the pearl oyster Pteria penguin was characterized through video analysis aided by open-source software. Juvenile pearl oysters were video-recorded for 48 hours under laboratory conditions, using commonly used surveillance hardware. The direct measuring of the distance changes between the two valve edges effectively revealed the pearl oysters’ tendency to open their valves wider at night-time, than during day-time. Moreover, the differences observed were also attained at the individual level. The description for the first time of this behavior has broader implications for the research in pearl oyster aquaculture. Moreover, it introduces a non-invasive tool for comprehensive assessment of adult oyster behavior.
