Indonesian Box Turtles are moderately sized animals, rarely exceeding eight inches as mature adults. Adult Indonesian Box Turtles have a domed carapace (top of the shell), while younger specimens usually have a flattened carapace. There are three subspecies of Indonesian Box Turtles. Of these, Cuora amboinensis kamarona has the most highly domed shell, while the carapaces of Cuora amboinensis amboinensis and Cuora amboinensis cuoro are flatter and longer. The shell of the Indonesian Box Turtle ranges from dark olive to black in color and rarely has visible markings. The main distinguishing features of this species of turtle are the three yellow stripes on either side of its head.
