簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 7; 背的軟條 (總數): 8-9; 臀棘 1; 臀鰭軟條: 8. This species is distinguished by the following characters: scales on cheeks and opercle; scales in predorsal midline 8-9; unbranched pectoral fin rays 16; branched 5th pelvic fin ray, 45-50% length of 4th ray; total gill rakers 20-22; broad interorbital (46-63% pupil width) with narrow crease-like postorbital trench ending at posterior-most papilla in row p; small nasal apparatus placed on the anterior one-third of snout with posterior nares forming posterodorsa margin of nasal sac; papillae in row p 7 (with a single papilla below row n); when alive or freshly collected, the dorsal surface of eye is dark blue; when preserved, with fairly evenly distributed melanophores over dorsal surface of snout (Ref. 118315).
Differs from Trimma meityae by having 16 pectoral fin rays (vs. 17-18), a branched 5th pelvic fin ray (vs. unbranched), with 7 papillae in row 'p' (vs. 8 papillae); and in live specimens, the blue colour over the top of the eyes is much darker in this species than in T. meityae (Ref. 118315).
Observed in mixed rubble and sand habitat, on a deep reef slope (at 60-70 m depth) and exposed to significant current and cold-water upwelling (Ref. 118315).

回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
