I learned a new, and important, word from this book: Umwelt, or, the world as it is experienced by a particular organism. This book does a deep dive into different umwelten (it even has a fun plural!) of a myriad of creatures and how their unique senses affect their experience, evolution, and species success. I think information like this is so helpful for us to take in to reduce our own egocentricies of our humanity and appreciate the world in which we live on another level. I especially loved the chapter on vision and colors. Would definitely recommend!
