Épines dorsales (Total) : 12 - 1; Rayons mous dorsaux (Total) : 10; Épines anales: 3; Rayons mous anaux: 8; Vertèbres: 24. This species is distinguished from all its congeners by the following set of characters: body deep, becoming compressed and slender with growth; D XII,10; the first 2 dorsal-fin spines are rudimentary (2 dorsal-fin spines on 1st dorsal pterygiophore), 3DFS longest (1.0-1.3, mean 1.2, in 3DFS/4DFS), third spine not reaching beyond first soft dorsal-fin ray origin, and less than head length; orbit diameter is subequal to suborbital depth. Colouration: body uniform pink with belly silvery and chin white, all fins pink. This species is often being confused with A. filamentosus and juveniles of A. spinifer; but it differs by having red spinous dorsal-fin rays (vs. yellow orange in true A. filamentosus from South Africa and Mozambique); also the third spinous dorsal-fin spine is longest (vs. third and fourth spines very elongate in A. filamentous and longest in A. spinifer) (Ref. 124569).
Usually caught on reefs, and feeds on benthic organisms and according to D. Golani (HUJF), this species is collected in deeper waters at 100-400 m (Ref. 124569).
