Appearance

Wood turtles have dark bodies with bright yellow or orange on their neck and the inside of their legs. The top of their heads is dark brown or black. Their shell is usually brown or black, but it can have spots or stripes of yellow. Their shell is made of circular growth rings that form small pyramid-like shapes. The bottom of the shell is yellow and has black markings around its edges. Males are slightly larger than females.

Feeding

Wood turtles are omnivores. Juvenile turtles tend to eat a higher protein diet than adults. They eat a variety of plants, insects and aquatic invertebrates.

Predators

Raccoons, skunks, opossums, otters, coyotes, foxes, ravens, crows and herons will eat wood turtle eggs or attack them as adults.

Reproduction and Life Cycle

Wood turtles reach sexual maturity when they are approximately 12 to 20 years old. Wood turtles mate in the fall and early spring. Females nest in late spring near streams. Females will lay a maximum of one clutch of eggs per year with each clutch containing seven to 11 eggs. The eggs hatch in late summer. The turtles will find an overwintering location by mid- to late October.
