Linear analyses of fins in <i>P</i>. <i>orbicularis</i>.

<p>Allometric relationships of dorsal and anal fins of <i>P</i>. <i>orbicularis</i> represented by single linear regression: A) Dorsal fin height regressed against SL; B) Anal fin height regressed against SL; C) Relative height of dorsal fin regressed against SL; D) Relative height of anal fin regressed against SL; E) Distance between the edges of dorsal and anal fins regressed against SL. Vertical dotted lines indicate transition between mimetic—non-mimetic (ca. 14 cm).
