珊瑚礁鱼是世界上色彩最丰富的动物之一。考虑到珊瑚礁上生活方式和栖息地的多样性，在许多情况下，颜色很可能是隐藏和交流之间的妥协。然而，人类对这种颜色的观察是有偏见的，因为我们的灵长类视觉系统。大多数动物的视觉系统与人类的“调谐”不同；针对可见光谱的不同部分进行了优化。为了理解珊瑚鱼的颜色，我们需要重建五颜六色的图案和背景，因为它们是通过鱼的眼睛看到的。在这里，研究人员测试了与珊瑚礁相关的触发鱼（Rhinecanthus aculeatus）的行为，以确定其颜色视觉的极限。这是第一次在珊瑚礁物种中展示行为颜色歧视阈值，是我们理解这个充满活力的色彩栖息地的交流和物种形成的关键一步。鱼被训练来区分奖励颜色刺激和一系列非奖励颜色刺激，并且发现区分阈值与基于受体噪声限制视觉模型和眼睛解剖结构的预测相吻合。因此，珊瑚鱼和各种动物的辨色能力现在可以用这里描述的参数来预测。
Coral reef fishes are among the most colourful animals in the world. Given the diversity of lifestyles and habitats on the reef, it is probable that in many instances coloration is a compromise between crypsis and communication. However, human observation of this coloration is biased by our primate visual system. Most animals have visual systems that are ‘tuned’ differently to humans; optimized for different parts of the visible spectrum. To understand reef fish colours, we need to reconstruct the appearance of colourful patterns and backgrounds as they are seen through the eyes of fish. Here, the coral reef associated triggerfish, Rhinecanthus aculeatus, was tested behaviourally to determine the limits of its colour vision. This is the first demonstration of behavioural colour discrimination thresholds in a coral reef species and is a critical step in our understanding of communication and speciation in this vibrant colourful habitat. Fish were trained to discriminate between a reward colour stimulus and series of non-reward colour stimuli and the discrimination thresholds were found to correspond well with predictions based on the receptor noise limited visual model and anatomy of the eye. Colour discrimination abilities of both reef fish and a variety of animals can therefore now be predicted using the parameters described here.
