Aristotle work on classification of animals is intereting and underdeveloped. Perhaps by just focusing on a section of his work like:
Book IV Animals without blood (non-vertebrates) - cephalopods, crustaceans, etc. In ch. 8, the sense organs of all animals.
Book V Reproduction, spontaneous and sexual of non-vertebrates
Book VI Reproduction of birds, fish and quadrupeds.

This way one would not have to write a book report on the whole thing and could focus on why he classified these animals in a certain way and how others would later be influenced by his system of catagorization. Also can be a point to show how Aristotle had a deep and continued understanding of the natural world and arguably a desire to make order and catalog creation/life.
