死亡旋渦 (蟻)

死亡旋渦sei2 mong4 syun4 wo1（death spiral，又有叫 ant mill）係行軍蟻有陣時會展現嘅一種行為^[1]^[2]。

概論[編輯]

行軍蟻工蟻嘅視力好差，近乎完全睇唔到嘢咁滯。每當佢哋要成群去（例如）搵嘢食嗰陣，會用觸鬚感覺同伴留低嘅費洛蒙痕跡，決定要向邊個方向行。有陣時可能會出咗錯，啲費洛蒙畀環境入面嘅嘢打亂咗，搞到其中有隊蟻同大隊走散。呢隊蟻搵唔到同伴留低嘅費洛蒙痕跡行返大隊，一隻同大隊走失咗嘅蟻唯一做到嘅，就係一味跟住自己前面嗰個同伴前進，但事實係佢前面嗰啲同伴又係一味淨係盲目跟住自己前面嘅同伴行，如是者呢隊走失咗嘅蟻就有可能會係噉原地打圈行，由上面睇佢哋望落就好似形成咗個旋渦（睇附圖幅 gif）噉嘅樣。

呢種現象叫「死亡旋渦」嘅原因係，進入咗呢種狀態嘅蟻好大機會搵唔到路返大隊，於是班蟻就會一路係噉打圈，直到佢哋冚唪唥都攰死為止^[3]。
