Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 16 - 17; Dorsal soft rays (total): 9 - 10; Anal spines: 7 - 8; Anal soft rays: 7 - 8; Vertebrae: 26 - 28. This species is similar to A. scitulus, but differs in having a lower dorsal 16 (vs.17) and anal 7 (vs. 8-9) fin spine counts; it has a higher dorsal ray count 10 (vs. 9); a shorter head; a larger interorbital distance; and lacks the diagnostic blotches on head and body which is usually present in A. scitulus (Ref. 74689).
