合齿鱼科辐鳍鱼纲仙女鱼目合齿鱼亚目的其中一

分布

鱼类分布在全球各大海域中。

深度

水深约10至80米。

特征

鱼种,体椭圆形或延长,略侧扁,头与躯干具被圆鳞。口极宽,背鳍短,有脂鳍,齿尖利,在上下颔、腭骨及舌面多成毛刷状,极少犬齿,较大的齿通能压伏。尾鳍分叉,无发光器,脊椎数多。

分类

本科其下分5个属,如下:

龙头鱼亚科(Harpadontinae)

龙头鱼(镰齿鱼)属Harpadon

蛇鲻属Saurida

狗母鱼亚科(Synodontidae)

狗母鱼属Synodus

大头狗母鱼属Trachinocephalus

生态

鱼类,栖息在沙泥地,甚或埋藏在沙中仅露出头部。只有少部分出现在珊瑚礁,其余多生活在较深水域,运动缓慢,以宽大而锐利的牙齿来追捕小鱼,只要被牠咬到的猎物很少有在逃脱的机会,亦捕食被海流冲过来的浮游生物

经际利用

体型小无重大经济价值,主因是本科鱼类肉松散无味,小且多刺。故一般多用于制造鱼松鱼浆
