Like coloration of the integument, eye color can be a significant but understudied component of communication and reproductive behavior. Eye color can change with sexual maturation and become sexually dimorphic, but in a few birds and fish, eye color can also change rapidly in response to the environment. There are few cases of the latter, and we report here several instances of such change in eye color in the Eastern box turtle (Terrapene carolina carolina), the first non‐avian tetrapod in which this capability has been reported. In male turtles, the iris changed from a pale yellow color (often characteristic of juveniles) to a bright red color (characteristic of mature males) in a period of <5 s. The nature of the color change is similar to that observed in some birds and suggests a common mechanism and/or adaptive role, which could be further explored in Eastern box turtles.

非禽类四足动物眼色快速变化的首次报道

像外皮的着色一样，眼睛的颜色可能是交流和生殖行为的重要但未被充分研究的组成部分。眼睛的颜色会随着性成熟而发生变化，并变成两性异形，但是在少数鸟类和鱼类中，眼睛的颜色也会随着环境的变化而迅速变化。后者的情况很少，我们在此报告东部箱龟（Terrapene carolina carolina），这是第一个报告有这种能力的非禽类四足动物。在雄龟中，虹膜在不到5 s的时间内从浅黄色（通常是幼鱼的特征）变为明亮的红色（成年雄性的特征）。颜色变化的性质类似于在某些鸟类中观察到的颜色，并暗示了一种共同的机制和/或适应性作用，可以在东方箱龟中进一步探索。
