臀鰭軟條: 6 - 7. Eye small, decreasing in relative size with growth; occipital processus widely separated from first interneural bone; juveniles as well as adults bluish on the back and sides, with a darkened area in front of the dorsal fin (more noticeable in juveniles); undersides of head and abdomen pale, and edges of upper and lower caudal fin lobes whitish (Ref. 42510).
眼小的, 隨著成長在相關的大小中漸減; 後頭骨活動第一個背側間的硬骨分得很開; 稚魚以及成魚藍色的在背部與側邊上, 在背鰭之前具有一個顏色較深區域;(更易見的在稚魚中) 頭部與腹部的下面灰白的, 與上、下尾鰭葉的邊緣微白色的.(參考文獻 42510)

50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00384 - 0.01800), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
