Baby Box Turtle
Interestingly, baby box turtles like this one does not have a hinged plastron (bottom shell) yet. When it gets older, its plastron will become hinged allowing it to close its shell. It will need to be approximately a quarter grown before developing this ability.
Notice the white area near the center of the plastron. This is called the yolk sac scar and is where the yoke is attached to the hatchling turtle.
