隸屬山蟻亞科的螞蟻，尾部具有可分泌酸性液體的器官。876Please respect copyright.ＰＥＮＡＮＡutC38YJaK4

甲酸(Formic Acid)是酸性液體的主要物質，普遍認作為抵禦外敵之用。876Please respect copyright.ＰＥＮＡＮＡvU4i2jL7LH

（圖2）研究(Ref1)發現，餵食山蟻亞科螞蟻含有10%蜜糖成份的水(pH5)後，其消化器官的pH值會有所降低;pH越低，泛指酸性越重。876Please respect copyright.ＰＥＮＡＮＡ6E2lDsZVCc

（圖手3）若果拑制螞蟻的舉動，進食蜜糖水後，其消化器官的pH值並不會有所下降。876Please respect copyright.ＰＥＮＡＮＡxLpDCdnqwm

後來發現，消化器官之所以進食後出現pH下降，是因為牠們進食後會咀嚼尾部的酸性分泌液所致。876Please respect copyright.ＰＥＮＡＮＡjIQwRKNCet

當牠們的行動被有所限制後，再也沒能「自食其酸」，因此消化器官的pH值並不會有所下降。876Please respect copyright.ＰＥＮＡＮＡ6Hpgd1Nf1k

（圖4）自食其酸的其中一道作用，就是能夠幫忙消除外來食物對自己有害的細菌。876Please respect copyright.ＰＥＮＡＮＡUeWp4rXG3g

研究故意注入特定的細菌到食物之中，再餵給螞蟻，亦能夠量度出該細菌並沒能夠在酸性分泌液中生存。876Please respect copyright.ＰＥＮＡＮＡFwjFBtYIIJ
876Please respect copyright.ＰＥＮＡＮＡshiUvQM0o3
而我們人類本身的胃部本身就懂得製作胃酸，並不需要「自食其酸」來抵禦外來細菌。876Please respect copyright.ＰＥＮＡＮＡtSL89bUgoe

除非高價買入GME股份，才會自食其酸。876Please respect copyright.ＰＥＮＡＮＡLPHrSH7Kzi
