What specific physical feature characterizes the carapace of the Wood Turtle (*G. insculpta*) distinguishing it morphologically?
Answer
It is heavily sculptured with ridges or raised scutes
The Wood Turtle possesses a distinctive and rugged external morphology primarily defined by its carapace structure. This shell is heavily sculptured, a feature often described as having distinct ridges or raised scutes. This substantial sculpting represents an evolutionary investment in defense, which aids the turtle in surviving numerous encounters with predators over its long lifespan, thereby supporting the fitness benefits conferred by its K-selected life strategy.
