Morphology | Morphometrics
Vertebrae: 100 - 103. This species is distinguished by having the following characters: body color grey, blackish reticular pattern; higher body depth; fewer vertebrae (100-103); teeth on jaw 3 rows, denser dentition, longer teeth; anus close to mid-body point; head length 6.4-7.3 in TL; trunk length 2.7-2.8 in TL; depth at gill opening 12.0-15.5 in TL; eye diameter 21.4-23.3 in HL; snout length 4.9-6.2 in HL (Ref. 79875).
Collected from rocky shores by longline and rotenone (Ref. 79875).
