What is the wisdom behind specifically mentioning some animals and plants in the chapters of the Holy Qur'an?

The chapters (surahs) mentioned were not exclusively about animals; rather, they were named after them due to the specific mention of these animals within them, distinguishing them from other chapters. The chapters were named to facilitate review and study, and their names are based on their descriptions, or by attributing them to something they specialized in mentioning, or to what was most extensively mentioned within them, or to words that appear in the chapter. As for the mention of dates, figs, olives, and similar things in the Qur'an, it is to draw attention to Allah's blessings and manifestations of His power, and due to their great importance and benefits. There is no redundancy or useless speech in the divine texts.
