Morphology | Morphometrics
This species is distinguished from its congeners except A. exulatus and A. schultzi by the position of the fourth supraorbital pore, anteromedial to the posterior nostril and separated from it by an interval of normal, pigmented skin; fewer vertebrae 98-108 (vs. 110-117 in A. exulatus and 105-113 in A. schultzi); longer snout-anus distance 45.1-50.6% TL (vs. 40.3-45.1% in A. exulatus and 41.5-45.1% in A. schultzi); with discrete, sharply defined pale spots (vs. larger, more diffuse pale areas oriented vertically in A. exulatus and uniform brown of A. schultzi) (Ref. 85321).
Most specimens were collected in relatively shallow water on coral reefs and rocky areas along the shore and are not recorded deeper than 10 m. Cryptic and rarely, if ever seen except when collected with ichthyocides (Ref. 85321).
