简单描述
检索表 | 型态特徵 | 形态测量图
Head and jaws very much compressed; body tapering posteriorly. Body depth at the middle about 1/13 of the entire length; the head about 1/7, measured to the branchial orifice. Jaws very narrow, sharp-pointed and equal. Gape deeply cleft. Teeth compressed at the sides, very sharp, slightly hooked and pointing backwards. Two tubular orifices above the eyes and two at the extremity of the snout. Distance of eyes from the end of the snout about twice the eye diameter. Branchial orifice and eyes of same size. Dorsal fin thick and fleshy. Color is fine dark purplish brown, with yellow circular spots; the spots mostly small. (Ref. 3157).
头部与颚非常扁长形; 身体后部尖端细的。 在中央的体高大约整个长度的 1/13; 头部大约 1/7, 从鳃孔测量了。 颚非常狭窄的，顶端尖的与相等的。 口裂很深。 齿扁长形的在侧边，非常锐利地，略微钩状的与朝向后面。 在眼上面的二个管状的孔口与二在吻部的末端。 眼睛到吻部末端的距离大约两倍于眼睛直径。 鳃孔与眼大小相同。 背鳍厚而肉质的。 色彩是纯深紫褐色的, 有黄色的圆形斑点; 斑点大部份小。 (参考文献 3157).
Often seen in shallow water. Remains under cover in rocky crevices during the day. Feeds mainly at night on crustaceans and fishes (Ref. 6852). Constantly opens and closes it mouth, an action required for respiration, not a threat (Ref. 5227).
在浅水区中的时常出现。 在岩石的裂隙中停留在表面下面在白天期间。 主要在晚上捕食甲壳动物和鱼类。 (参考文献 6852) 它的嘴巴不断地张开与合闭, 一个行动对于呼吸是必需的, 不是一个威胁.(参考文献 5227)
