Dusky surface coloration darker on dorsal and dorsolateral regions of body, with dark chromatophores dense on scales above lateral line, less concentrated on lateral line and almost absent on scales below lateral line. Reticulate pattern on almost all body due to higher concentration of dark chromatophores on scale margins, with anterior margin sometimes separated from middle region of scales by dark line of chromatophores. Reticulate pattern more conspicuous on middle region of body due to contrasting regions of scales; pattern not evident in ventral region of body, disappearing around fourth or fifth scale row below lateral line. Deep-lying, dark chromatophores forming faint, dusky midlateral stripe on body. Stripe more evident posterior of vertical through adipose-fin terminus, forming a longitudinally elongated caudal peduncle blotch that extends into base of middle caudal-fin rays. Middorsal region of body darker with dark stripe extending from tip of supraoccipital to dorsal margin of procurrent caudal-fin rays. Dorsal, anal, and caudal fins somewhat dusky with margins outlined by small, dark chromatophores. Dark pigmentation developed proximally on caudal-fin lobes, dorsal and anal fins. Pectoral and pelvic fins with rays outlined by small, dark chromatophores. Adipose fin speckled with small dark chromatophores.

derives from Ancient Greek ὨΡΊων (Ōríōn) which means “heaven’s light”, or Arion, which means “warrior”. In ancient Greek mythology, Orion was a giant hunter who, after being killed by Scorpion sent by Earth mother Gaia, either Zeus or Artemis placed in the night sky as the constellation Orion. The Orion Constellation contains the Great Orion Nebula, one of the brightest nebulae in the visible sky, and the Orion’s Belt asterism formed by three bright blue supergiants: the triple star system Alnitak, the major star Alnilam, and the multiple star system Mintaka.
