生物学家发现,有一种夜间出来活动的飞蛾,能在漆黑的夜晚看见彩色的花朵。它们正是利用这种视觉上的本领,专门在夜晚寻找黄色的、充满花蜜的花朵以获取食物。这是首次发现有夜视功能的动物,而这一发现表明,其他物种也有利用色视觉寻找目标的夜视功能。生物学家认为,飞蛾在夜间是通过寻找较暗叶子下发亮的花瓣,来寻找黄色花朵的。叶子和花瓣在亮度上的这种差别可以解释为:为什么黑白照片
Biologists have discovered that moths that come out at night can see colored flowers on dark nights. They are using this visual skill to search for yellow, nectar-bearing flowers at night to obtain food. This is the first time that animals with night vision have been discovered. This finding suggests that other species also have night vision capabilities that use color vision to find the target. Biologists believe that moths look for yellow flowers at night by looking for bright petals under darker leaves. This difference in brightness between leaves and petals can be explained by: Why black and white photos
