3 stars. While I was very excited about this book, I got off to a rough start with it. I found a typo on the second page (and several more throughout the book) and the author used the word "landlocked" 3 times in as many pages. I knew then that this book, as several others have noted, could have used some more careful editing (personally, I think it could have easily been trimmed by 50 pages or more). Also, as a few other reviewers have noted, the memoir parts of this book weren't very engaging. By the end of the book, I was a little tired of hearing about her family, her college experiences, and her ill-fated romance with the ichthyologist surfer. I was just here for the jellyfish. I also feel like this book led me to believe that we were going to learn a little more about climate change and jellyfish and while that was covered some, it was not covered to the extent that I thought it was going to be. We do, however, learn about the science of jellyfish, so the book delivers there. I do wish there had been a clear diagram of a common jellyfish in the book to guide the reader because for much of the discussion, you need to have a basic understanding of the parts of a jellyfish. I think a reference diagram would have been a great help for this book to help orient the reader as we delve into jellyfish capabilities throughout the text. I did enjoy this book overall, despite my notes above, and wanted to share some of the best jellyfish facts I learned from the book:
- Jellyfish is protein packed, with one serving (she doesn't explain what a serving is, but oh well) containing just 25 calories and a whopping 6 grams of protein. There is no fat. We also learn that when prepared properly, it is crunchy and the taste resembles "green bell pepper". Yum?
- Jellyfish are the most efficient swimmers in the world! The chapter that focuses on this, "Robojelly", highlights some particularly interesting research on the mechanics of jellyfish swimming and robotic jellyfish.
- From the chapter "Life's Limits": They are finding that some species of jellyfish might be ageless because they can revert to a previous life stage and regrow into a healthy adult and then continue to repeat this cycle over and over again.
- The description of a box jelly sting from the champion endurance swimmer Diana Nyad, was horrific; she said it felt like her "entire body was dipped in hot oil." (pg. 252). I did like the subsequent discussion of the swimsuits and other technologies that are being created to help prevent jellyfish stings as humans and jellyfish increasingly come into contact with one another.
- From the chapter "Sting Block": "The acceleration of the stinging cell is 5 million g. It's thought to be the fastest motion in the animal kingdom". 'G' in the preceding quote stands for g-force. In case you were curious, this is really, really fast.
I also didn't know a lot about jellyfish before I read this book but now have a greater appreciation for a creature that looks so simple from the outside, but is a lot more complex than I would have imagined!
