What color are the eyes of male eastern box turtles?

Male eastern box turtles typically have distinctive red eyes, which is a key characteristic that helps in identifying their sex. The bright red eyes are indicative of adult males and serve both biological and behavioral functions, signaling to potential mates and rivals. This vivid coloration is a result of the presence of pigments and can vary in intensity among individuals, but the general red hue is a consistent trait among males of the species.

In contrast, females usually have brown or yellowish-brown eyes. This difference in eye color is one of the clear morphological distinctions used in sex identification of eastern box turtles. Understanding these traits not only helps in recognizing the species but also contributes to broader studies of turtle biology and behavior in their habitats.
