簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 9; 背的軟條 (總數) : 11; 臀棘: 3; 臀鰭軟條: 12; 脊椎骨: 25. This species is distinguished from its congeners by the following characters: body elongate with greatest body depth 22.6-25.3% SL; D IX,11; A III,12; pectoral-fin rays 13; tubed lateral-line scales 28. Colouration: interspinous membrane between anterior two to three spines of dorsal fin has a black spot; males with head yellow and extensively reticulate; abdominal region behind pelvic and pectoral fins is orange to orange-pink with yellow crosshatch markings; posterior part of body purple black; females are distinctly bicolored, orange-brown dorsally, white ventrally (Ref. 123182).
P. atavai 的初期階段非常近似稚魚 Thalassoma amblycephalum; 最後階段在身體上的頭部與淡紅的水平與垂直的線上前面地以暗紫羅蘭色的 squiggly 線是橘黃色的, 在後部地變成突然藍黑色。 (參考文獻 1602) 尾鰭不是很短.(長度 1.3 到 1.5 倍頭長) 第一背鰭鰭條長的。 吻 2.7 到 2.9 倍頭長 (參考文獻 9823).

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 26.3, mean 26.1 °C (based on 12 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00470 - 0.02030), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
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. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 95.7 [56.8, 165.3] mg/100g; Iron = 0.759 [0.442, 1.405] mg/100g; Protein = 18.5 [15.6, 20.7] %; Omega3 = 0.163 [0.103, 0.261] g/100g; Selenium = 23 [13, 42] μg/100g; VitaminA = 151 [47, 567] μg/100g; Zinc = 1.77 [1.20, 2.76] mg/100g (wet weight);
