provided by The Fish Database of Taiwan
吻非常長且狹窄。體盤寬度約尾長的1.6倍(成熟雄魚)、1.7倍(成熟雌魚)。兩眼眶距離寬且扁平,兩眼眶寬及吻長的比例在成魚時變異較大,其範圍在4.3-5.3倍。眼睛小,兩眼眶距離為眼直徑的1.0-1.8倍(成魚階段)。當成熟時,背部的刺超過體盤中間、體盤邊緣吻的尖端(雌)、眼框內全部的部位(雄)及頭部腹面也有微小的刺分布;眼眶邊緣的刺不規則排列,一般只有一根,但偶爾會有2-4根。體盤背部的中間會有一列刺一直延伸到尾部,數量約為20-40根,而雌魚數目大於雄魚。兩背鰭之間也有刺,其中完全成熟雌魚之特徵為一列大刺分布在尾部,有時在尾部邊緣也會生長尖刺。體盤腹部除了頭不以外其餘皆為平滑。背部顏色成不均勻的棕色或接近灰棕色。(陳柔蓉、林沛立2012/11編寫)
