隸屬山蟻亞科的螞蟻，尾部具有可分泌酸性液體的器官。807Please respect copyright.ＰＥＮＡＮＡ7JTyj7PvOZ

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。807Please respect copyright.ＰＥＮＡＮＡi9rEnqFOyL

（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。807Please respect copyright.ＰＥＮＡＮＡy4d03WSp26

（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。807Please respect copyright.ＰＥＮＡＮＡA5SweEgL0Y

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。807Please respect copyright.ＰＥＮＡＮＡcNyC4mMX3h
807Please respect copyright.ＰＥＮＡＮＡOUpZVYTbzo
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。807Please respect copyright.ＰＥＮＡＮＡwQ4lOXVGhS

（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。807Please respect copyright.ＰＥＮＡＮＡM3GlkHIT0T

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。807Please respect copyright.ＰＥＮＡＮＡsfPqQNTjwI
807Please respect copyright.ＰＥＮＡＮＡD4RI94v0W1
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。807Please respect copyright.ＰＥＮＡＮＡrVnPPKVVuu

除非高價買入GME股份，才會自食其酸。807Please respect copyright.ＰＥＮＡＮＡ75rkefj6Vx
