20个不同的面部特征的珊瑚礁鱼类进行了形态测量分析，以评估线索，可以为捕食者识别。本研究包括35个不同科的105个不同种类。潜在判别值的主要特征是头宽、头形、嘴的大小和形状、眼睛的形状、眼睛的直径和眼睛之间的距离。颜色和图案没有潜在的区分价值。判别函数分析表明，两个线索，眼睛之间的距离和嘴的大小，是足够的良好的捕食者识别。捕食性鱼类的食鱼线索的伪装进行了讨论。模拟食鱼线索的一些猎物鱼类作为一种反捕食者的策略，建议为两种类型的假眼斑模拟正面的食鱼。
A morphometric analysis of 20 different facial features of reef fishes was carried out in order to assess cues which could serve for predator recognition. 105 different species of 35 different families were included in this study. The main features of potential discriminatory value were head width, head shape, the size of the mouth and its shape, the shape of the eyes, their diameter, and the distance between the eyes. Color and pattern were of no potential discriminatory value. Discriminant function analysis showed that two cues, the distance between the eyes and the size of the mouth, were sufficient for good predator recognition. The camouflage of piscivorous cues by predatory fish is discussed. The mimicry of piscivorous cues by some prey fishes as an anti-predator strategy is suggested for two types of false eye spots simulating the frontal aspect of a piscivore.
