I recommend this book a lot, but 'Cats’ Paws and Catapults: Mechanical Worlds of Nature and People' (https://www.goodreads.com/book/show/223609.Cats_Paws_and_Catapults https://www.goodreads.com/book/show/223609.Cats_Paws_and_Cat...) is a great look at how biology inspires human design. One idea that is important (IIRC from this book) is that many examples are really inspiration, and not direct copying of design. Biology works very differently to human machines, with very different constraints, so when engineers and designers try to stick too closely to the biological original, it may not work out very well!
