What evidence commonly points to mollusks being a significant food source for wild Wood Turtles?

Answer

Snail shell fragments stuck to the beak

Observations in the natural habitat of the Wood Turtle provide direct evidence of their dietary preferences. A common indicator that mollusks, such as snails, form a significant portion of their intake involves examining the turtle itself. Specifically, the presence of fragments of snail shells adhering to the Wood Turtle’s beak serves as a clear physical sign that the turtle has recently consumed these shelled creatures, highlighting mollusks as a meaningful part of their animal protein intake.
