Morphology | Morphometrics
(total): 16 - 17;
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).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00598 - 0.04201), b=2.99 (2.76 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
