Etymology: Gymnocranius: Greek, gymnos = naked + Greek, kranion = skull (Ref. 45335).

生态学
海洋 礁区鱼类; 非迁移的; 深度上下限 15 - 80 m (Ref. 2295). 熱帶; 35°N - 9°S
Indo-West Pacific: southern Japan to the Indo-Malaysian region, probably eastward to India. Has often been confused w/ the young of Gymnocranius grandoculis, hence its distributional limits are somewhat obscure. Records of Gymnocranius griseus from the Western Indian Ocean probably pertain to Gymnocranius grandoculis.
印度-西太平洋: 日本南部到印度-馬來群島區域,可能向東至印度。 已經時常是困惑的 w/ 藍線裸頂鯛〔Gymnocranius grandoculis〕 的幼魚, 它的分佈限制由此而來是略微模糊。 白鱲〔Gymnocranius griseus〕 從西印度洋的記錄可能屬於 藍線裸頂鯛〔Gymnocranius grandoculis〕 。

眼直径是相当大的, 它的直径大约等于或略大超过眶前骨与眼间骨宽度。 整体的色彩是银色的, 侧边上经常有一个 5 到的扩散生动图案 8条狭窄的深色横带, 包括一个经过眼与越过颊部。 鳍主要是清澈的到淡黄色的; 有时在背鳍、尾鳍与臀鳍上有扩散的杂斑或斑点。 时常有横过胸鳍的基底的一条狭窄的褐色横带。 一些成鱼在吻部与颊上持有一些分散的蓝色斑点或杂乱的斑纹。 (参考文献 2295) 相当卵形的身体与尖的尾叶是明显的。 (参考文献 37816)
In sheltered coastal bays and sand and mud slopes in depths over 20 m (Ref. 48635); also in coastal trawling grounds. Juveniles sometimes in shallow estuaries on algae reefs (Ref. 48635). Sometimes forms schools. Feeds on bottom-living invertebrates. Sexually mature upon reaching 15-17 cm SL. Sometimes caught with handlines and marketed dried (Ref. 9775) or fresh. In Hong Kong live fish markets (Ref. 27253).
在掩蔽的近岸海湾与沙子与泥斜坡深度超过 20 公尺中;(参考文献 48635) 也在海岸的拖网渔场中。 稚鱼有时在水浅的河口中在藻礁上.(参考文献 48635) 有时形成鱼群。 吃底栖无脊椎动物。 性成熟当达到 15-17 公分 SL。 有时用手执的钓丝捕获了而且在市场上销售乾燥的 (参考文献 9775) 或新鲜的。 在香港活鱼贩售。 (参考文献 27253)
