Predatory attempts per fish on blue crab prey (± 1 SE) by lionfish and juvenile red, lane, and gray snappers during control and interaction experiments.

Data in the top panel are from interaction trials between lionfish (lion) and snapper species (gray, lane, or red snapper), and data in the bottom panel are from lionfish and snapper monoculture control trials of three and four individuals of a given snapper species and one or four individuals for lionfish (lion). Capitalized letters above bars denote significant groupings (ppost-hoc pairwise comparisons. No standard error was observed for lane snapper in lane snapper-lionfish interaction trials or for lionfish in red snapper-lionfish interaction trials.
