Spineless Book Talk


Get your hands in a bucket of earth worms. Explore the world of spineless creatures and test your knowledge with Invertebrate Trivia!


Join the Science Mill and author Juli Berwald for a discussion of her new book, Spineless: The Science of Jellyfish and the Art of Growing a Backbone. 

Berwald, a former ocean scientist, went in pursuit of the slippery story of jellyfish, rediscovering her passion for marine science and the sea’s imperiled ecosystems.

Jellyfish are an enigma. They have no centralized brain, but they see and feel and react to their environment in complex ways. They look simple, yet their propulsion systems are so advanced that engineers are just learning how to mimic them. They produce some of the deadliest toxins on the planet and still remain undeniably alluring. Long ignored by science, they may be a key to ecosystem stability.

Juli Berwald’s journey into the world of jellyfish is a personal one. More than a decade ago, she left the sea and her scientific career behind to raise a family in landlocked Austin, Texas. Increasingly dire headlines drew her back to jellies, as unprecedented jellyfish blooms toppled ecosystems and collapsed the world’s most productive fisheries. What was unclear was whether these incidents were symptoms of a changing planet or part of a natural cycle.

Berwald’s desire to understand jellyfish takes her on a scientific odyssey. She travels the globe to meet the scientists who devote their careers to jellies; hitches rides on Japanese fishing boats to see giant jellyfish in the wild; raises jellyfish in her dining room; and throughout it all marvels at the complexity of these fascinating and ominous biological wonders. Gracefully blending personal memoir with crystal-clear distillations of science, Spineless reveals that jellyfish are a bellwether for the damage we’re inflicting on the climate and the oceans and a call to realize our collective responsibility for the planet we share.

A 30-minute discussion of the book will be followed by a Q&A moderated by Dr. Robert Elde, the Science Mill's Science Director and Vice Chair of the Board, and former Dean of the University of Minnesota’s College of Biological Sciences.

This discussion will take place in the Science Mill's theater. Copies of the book will be for sale and author signing after the discussion.

Bring the kids from 11am-2pm and discover the spineless marvels of the insect world: arachnids, centipedes and earthworms! Get your hands in a bucket of earth worms or play Invertebrate Trivia!
