Abstract

When frightened by a predator, the plesiopid fish, Calloplesiops altivelis, adopts a posture and appearance that mimics the head of a noxious moray eel, Gymnothorax meleagris. Tests indicate that the mimicry is Batesian and not Müllerian. Unlike the strategy of other reef-fish prey species, which hide when threatened, the Calloplesiops's strategy is one of intimidation.
