对热带珊瑚礁鱼类模仿行为的研究通常很少或根本没有考虑到对无关的、看起来相似的物种之间的行为关联的其他解释，这些解释有利于假定的模仿者。我提出并评估了这样一种替代解释。通过模仿，模仿者与其模型相似，进化成这样是为了响应模仿目标的选择，并从这种相似中获得进化的好处。在另一种情况下，即社会陷阱假说，模型与“模仿者”的巧合相似性无意中吸引了后者，通过学习的好处加强了这种社会陷阱，导致“模仿者”经常与模型联系。我检查三个众所周知的情况下，假设的攻击性模仿珊瑚礁鱼类之间的关系，从这些假设的九个预测，并评估哪个假设提供了一个更好的解释。一个案例涉及精确而复杂的形态和行为相似性，与模仿非常一致，一个是不确定的，一个更符合基于巧合的社会陷阱，不精确的相似性。热带珊瑚礁鱼类之间的假设种间拟态的情况下，已经深入研究，许多这样的协会可能涉及社会陷阱所产生的广义的，巧合的相似性。拟态在这些鱼类中可能比一般认为的要少得多。
Studies of mimicry among tropical reef-fishes usually give little or no consideration to alternative explanations for behavioral associations between unrelated, look-alike species that benefit the supposed mimic. I propose and assess such an alternative explanation. With mimicry the mimic resembles its model, evolved to do so in response to selection by the mimicry target, and gains evolved benefits from that resemblance. In the alternative, the social-trap hypothesis, a coincidental resemblance of the model to the “mimic” inadvertently attracts the latter to it, and reinforcement of this social trapping by learned benefits leads to the “mimic” regularly associating with the model. I examine three well known cases of supposed aggressive mimicry among reef-fishes in relation to nine predictions from these hypotheses, and assess which hypothesis offers a better explanation for each. One case, involving precise and complex morphological and behavioral resemblance, is strongly consistent with mimicry, one is inconclusive, and one is more consistent with a social-trap based on coincidental, imprecise resemblance. Few cases of supposed interspecific mimicry among tropical reef fishes have been examined in depth, and many such associations may involve social traps arising from generalized, coincidental resemblance. Mimicry may be much less common among these fishes than is generally thought.
