Moderately slender body; head and jaw size moderate; eyes large and nearly round; snout blunt; gut to midbody with slight sigmoid curvature; pigment sparse but diagnostic (see Ceratoscopelus townsendi; Br2 photophores form at about 5.0 mm; Br1, Op1, and PO5 form during transformation; larvae somewhat similar to those of C. townsendi but are stouter, have a larger, more round eye, have embedded pigment in the otic region (lacking in C. townsendi larvae <10.5 mm), and lack early developing photophores present in C. townsendi larvae. Pigmentation: Preflexion: 3-9 (usually 4-6) in median ventral series extending posteriad from above preanal arch of gut; 1 above gas bladder by 4.0 mm; 1 embedded in otic region in larvae as small as 4.4 mm. Flexion: by 5.0 mm, postanal series coalesces to 1, occasionally 2, in caudal peduncle region in larvae as small as 5.3 mm. Postflexion: all larvae >7.0 mm have series above spinal column, 1-9 (usually 2-3), 1 or 2 in dorsal midline posterior to cerebellum at about 8.0 mm. Sequence of fin development: caudal, dorsal and anal and pectorals, pelvics.
