簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 28 - 31; 臀鰭軟條: 25 - 28; 脊椎骨: 47 - 48. This species is distinguished from A. nudiceps by the presence of two dark vertical bands
of pigment on the body; a larger body depth at the origin of the anal fins; and a shorter snout and jaw length.The smallest adult specimen examined was 12.73 mm SL, although the sex was not determined. It is unknown when the characteristic dark vertical bands develop in this species, although it has been reported that these do not appear on larvae up to 2.07 cm SL (Ref. 131869).
Cross section: compressed.
Adults were captured at 600-705 m while larvae were captured at 215-964 m; habitats at these depths in coastal regions of Antarctica are likely composed of similar fine sediments (Ref. 131869).
