鋸針蟻屬 (Odontomachus ) 又稱大齒猛蟻屬，隸屬蟻科針蟻亞科，棲息於熱帶和亞熱帶，為肉食性。
鋸針蟻屬具有觸發式大顎 (trap-jaw)，大顎能以極快的速度關上，以捕捉獵物或是透過反作用力彈飛自己躲避敵人。
總覽
鋸針蟻屬英文俗名trap-jaw ants ，鋸針蟻屬有一對發達的大顎，打開的角度可達180度。大顎可以透過內部的結構固定在打開的姿勢，大顎的內部生有一對用來感知的板機毛 (trigger-hair)，當獵物觸碰到板機毛 (trigger-hair) 時大顎便會快速關上，大顎強而有力，且運動速度極快，鋸針蟻屬的英文俗名便是由此而來，大顎命中獵物時會殺死或使獵物殘廢。如果大顎沒有命中目標，鋸針蟻屬可以重複地固定大顎、擊發大顎，除此之外，鋸針蟻屬也可以像其他螞蟻一樣正常開闔大顎。鋸針蟻屬也會利用大顎來擊飛敵人，或是彈飛自己以躲避敵人[1][2]。
鋸針蟻屬的幼蟲外形特殊[3]，其身體上生有長長的肉脊，且其背部生有黏著墊，可以用來黏在蟻巢的牆壁上[4]。幼蟲為肉食性，幼蟲會蛻皮三次[4]，幼蟲會利用其他介質結繭[5]。
大顎運動的速度
鋸針蟻屬大顎運動的速度是動物界中第二快的[1]，第一快的是德古拉蟻 (Mystrium camillae )[6]。有研究指出 Odontomachus bauri 大顎運動的速度介於時速 126 ~ 230 公里。大顎關上的時間平均為 130 微秒。加速度可達 1 000 000 m/s²。
擬態
Enoplomischus 屬的跳蛛會擬態成鋸針蟻屬[7]。
分布
鋸針蟻屬分布於中南美洲、亞洲、澳洲與非洲[8]。有研究指出在美國「Odontomachus haematodus 1956年在阿拉巴馬州被記錄到，但近期研究者指出該物種已沿著墨西哥灣散播，最遠至佛羅里達州的彭薩科拉[9]。」Magdalena Sorger則指出，「在過去，Odontomachus ruginodis 的分布範圍被認為侷限在奧蘭多地區，而近期有一筆 O. ruginodis 的紀錄出現在奧蘭多北邊超過100英里處，位於佛羅里達州的蓋恩斯維爾[10]。」而 Odontomachus relictus 則只在佛羅里達中部發現，棲息於長有灌木叢的沙脊地形中[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.
