Mimicry appears to be a widespread and common phenomenon in coral reef fishes with approximately 60 reported cases. Although many are largely anecdotal accounts based on colour resemblance recent quantitative comparisons and experimental manipulations have confirmed that many do represent mimic-model relationships. The distribution of mimics and models among reef fish families appears largely serendipitous. Mimics are most common in the families Blenniidae Serranidae and Apogonidae and models in the families Pomacentridae Blenniidae and Labridae. Mimics and model species usually represent less than 10 of species within families although imperfect forms of mimicry are likely to have been underestimated. Mimicry appears to be particularly important during juvenile stages with 28 of mimic species losing their mimic colouration when they outgrow their models. All cases of mimicry support predictions that mimics are rare relative to their models. Furthermore the abundance of mimics in different areas may increase in proportion to model abundance. The spatial distribution of mimics appears to be limited by that of their model species although some change models in different habitats or in different parts of their range. Many mimics live in close association with their models and both foraging advantages and predator avoidance .
