Juli Berwald book, "Spineless"
The story of jellyfish is a slippery one. Jellyfish have been swimming in our oceans for over half a billion years—longer than any other animal. Made of roughly 95% water, jellyfish are both virtuosos of disguise, nearly imperceptible against their watery background, and the bearers of a luminescence that revolutionized biotechnology. In the rhythmic movements of their tentacles that carry the threat of a thousand of toxic stings, jellyfish haunt the space between our own heartbeat and mortal danger. Jellyfish are a muse both angelic and demonic.

Years ago, I left oceanography to raise a family in landlocked Austin, Texas, but jellyfish took me back to the sea. Blending personal memoir with crystal-clear distillations of science, Spineless: The Science of Jellyfish and the Art of Growing a Backbone tells the story of how I learned to navigate and ultimately embrace my ambition, curiosity, and passion for the natural world. I discover that jellyfish science is more than a quest for answers. It’s a call to realize our collective responsibility for the planet we all share.
