Graphs comparing carapace dimensions of instars of Strobilopterus. Circles represent specimens of Strobilopterus proteus, while triangles represent Strobilopterus richardsoni and squares represent Strobilopterus princetonii. A: Carapace length vs. carapace width. The regression line is length = 0.5825(width) + 1.4404 and is statistically significant (r2 = 0.99034, 8 degrees of freedom, p = 2.39×10-9) indicating that the relationship between carapace length and carapace width is not random and therefore likely due to ontogeny. B: Carapace length:width ratio vs. carapace length. Instar groupings are shown, with the potential subdivision of the δ specimens shown with dashed lines. C: Carapace length:width ratio vs. carapace width. Instar groupings are shown, with the potential subdivision of the δ specimens shown with dashed lines.
