Are juvenile coral-trouts (Plectropomus) mimics of poisonous pufferfishes (Canthigaster) on coral reefs?

Abstract

The juveniles of three species of coral-trout (Plectropomus) resemble two species of poisonous pufferfish (Canthigaster), one of the latter having two distinct colour morphs. Qualitative data are assembled on the diet, feeding mode, palatability, relative abundance, habitat and geographical range of each species. All observations are consistent with the hypothesis that juvenile coral-trouts are generalized mimics of pufferfishes. Speciation within Plectropomus is discussed with respect to its mimetic relationships with Canthigaster.
