I found an issue in Nahj al-Balagha's sermon 185 (or some editions 184), which is one of the most popular and eloquent and beautiful sermons in Nahj al-Balagha, in which it says that ants have ears in their heads, but this is scientifically false, but the Imam might have used the word "ear" simply to refer to the antennae. But why would he describe them as "ears" though? Why not simply "two columns" etc.?
Maybe the Imam was just being poetic and graphic, or maybe there is some scientific truth in this that is yet to be discovered?
