Body color and texture components and patterns of the Larger Pacific Striped Octopus.
A) Spot-and-striped display with flared body posture, showing longitudinal head stripes and (1) dark horizontal mantle bars; B) Bilateral display with dark body pattern on the left of the individual’s midline (viewer’s right) (2), and spot-and-stripe body pattern on the right of the individual’s midline (viewer’s left); C) Spot-and-stripe display highlighting (3) region with individual variation in body color components; D) Dorsal arm crown and arms in spot-and-striped body color pattern showing (4) white sucker rims and (5) pale longitudinal stripes on head, with raised pale border; E) Lateral view showing smooth skin and (6) large white spots on web, arm crown and arms; F) White spots on the raised bumps of granular skin texture, on dorso-lateral edges of arms (7); G) Dorsal arm crown and arms in dark color pattern showing (8) dark stripes with pale raised border; H) Dorso-lateral view in pale color pattern showing (9) raised pale border between horizontal mantle bars on dorsal mantle and (10) small mantle papillae; I) Eyes and funnel showing (11) granular skin texture, (12) dark eye bar, and (13) supra-(left) and sub-(right) ocular papillae.
