- Females have a flat plastron and typically dull yellow or brown eyes, while males have a concave plastron and usually bright red or orange eyes.
- A Box turtle’s plastron is hinged, so that it can be brought up in the front and back to meet the carapace and completely seal the turtle inside.
- Females can carry their eggs inside them for up to 4 years if environmental conditions are not favorable, and wait to lay the eggs until a better time.
