Although the role of colour in mate choice is well known, few tests of colour vision have been based on mating behaviour. Females of the fiddler crab Uca mjoebergi have recently been shown to use claw coloration to recognize conspecific males. In this study I demonstrate that the females use colour vision for this task; preferentially approaching yellow claws over grey claws regardless of their intensity while failing to discriminate between yellow claws differing in intensity. This is one of only a handful of studies confirming the involvement of colour vision in mate choice and the first conclusive evidence in fiddler crabs.
虽然颜色在配偶选择中的作用已广为人知，但基于交配行为进行的色觉测试却很少。最近有研究表明，招潮蟹Uca mjoebergi的雌性会利用螯的颜色来识别同种雄性。在本研究中，我证明了雌性在这项任务中使用色觉；它们会优先接近黄色螯而非灰色螯，无论其亮度如何，同时无法区分亮度不同的黄色螯。这是仅有的少数几项证实色觉参与配偶选择的研究之一，也是招潮蟹的首个确凿证据。
