锯针蚁属 (Odontomachus ) 又称大齿猛蚁属，隶属蚁科针蚁亚科，栖息于热带和亚热带，为肉食性。
锯针蚁属具有触发式大颚 (trap-jaw)，大颚能以极快的速度关上，以捕捉猎物或是透过反作用力弹飞自己躲避敌人。
总览
锯针蚁属英文俗名trap-jaw ants ，锯针蚁属有一对发达的大颚，打开的角度可达180度。大颚可以透过内部的结构固定在打开的姿势，大颚的内部生有一对用来感知的板机毛 (trigger-hair)，当猎物触碰到板机毛 (trigger-hair) 时大颚便会快速关上，大颚强而有力，且运动速度极快，锯针蚁属的英文俗名便是由此而来，大颚命中猎物时会杀死或使猎物残废。如果大颚没有命中目标，锯针蚁属可以重复地固定大颚、击发大颚，除此之外，锯针蚁属也可以像其他蚂蚁一样正常开阖大颚。锯针蚁属也会利用大颚来击飞敌人，或是弹飞自己以躲避敌人[1][2]。
锯针蚁属的幼虫外形特殊[3]，其身体上生有长长的肉脊，且其背部生有黏着垫，可以用来黏在蚁巢的墙壁上[4]。幼虫为肉食性，幼虫会蜕皮三次[4]，幼虫会利用其他介质结茧[5]。
大颚运动的速度
锯针蚁属大颚运动的速度是动物界中第二快的[1]，第一快的是德古拉蚁 (Mystrium camillae )[6]。有研究指出 Odontomachus bauri 大颚运动的速度介于时速 126 ~ 230 公里。大颚关上的时间平均为 130 微秒。加速度可达 1 000 000 m/s²。
拟态
Enoplomischus 属的跳蛛会拟态成锯针蚁属[7]。
分布
锯针蚁属分布于中南美洲、亚洲、澳洲与非洲[8]。有研究指出在美国“Odontomachus haematodus 1956年在阿拉巴马州被记录到，但近期研究者指出该物种已沿着墨西哥湾散播，最远至佛罗里达州的彭萨科拉[9]。”Magdalena Sorger则指出，“在过去，Odontomachus ruginodis 的分布范围被认为局限在奥兰多地区，而近期有一笔 O. ruginodis 的纪录出现在奥兰多北边超过100英里处，位于佛罗里达州的盖恩斯维尔[10]。”而 Odontomachus relictus 则只在佛罗里达中部发现，栖息于长有灌木丛的沙脊地形中[11]。

One species called Odontomachus haematodus was unofficially recorded in Alabama back in 1956. But now researchers have officially confirmed that the species has spread across the Gulf Coast, at least as far east as Pensacola, Florida.

As recently as a few years ago, another species called Odontomachus ruginodis was thought to be confined to the Orlando region, and points south. But now Sorger has confirmed a record of ruginodis more than a hundred miles north of Orlando, in Gainesville, Florida.

Not all of the trap-jaw species are on the move, however. Sorger also studies Odontomachus relictus, a species that is found only in endangered scrub habitat on central Florida’s ancient sand ridges.
