Fig. 2. Characteristics of the carapace of a CT-scanned smooth turnkfish (17.0 cm
total length, 12.3 cm carapace length) plotted as a function of percentage of
carapace length. Dimensions (carapace width, carapace height, and eye ridge
width) are depicted on the left y-axis, while mean ventro-lateral
keel angle and dorsal keel angle are depicted on the right
y-axis.
