The number of lionfish that moved between reefs and seagrass in Eleuthera, Bahamas from July to August in 2012

<p>This was an observational field study on natural patch reefs with varying lionfish densities to determine if lionfish behavior and movements change at different local lionfish and prey fish densities. &nbsp;Each reef was visited at three times of day: dawn, midday, and dusk, and two focal lionfish were observed during each visit at each reef.
