A former ocean scientist goes in pursuit of the slippery story of jellyfish, rediscovering her passion for marine science and the sea's imperiled ecosystems.

Jellyfish have been swimming in our oceans for well over half a billion years, longer than any other animal that lives on the planet. They make a venom so toxic it can kill a human in three minutes. Their sting--microscopic spears that pierce with five million times the acceleration of gravity--is the fastest known motion in the animal kingdom. Made of roughly 95 percent water, some jellies are barely perceptible virtuosos of disguise, while others glow with a luminescence that has revolutionized biotechnology. Yet until recently, jellyfish were largely ignored by science, and they remain among the most poorly understood of ocean dwellers.

More than a decade ago, Juli Berwald left a career in ocean science to raise a family in landlocked Austin, Texas, but jellyfish drew her back to the sea. Recent, massive blooms of billions of jellyfish have clogged power plants, decimated fisheries, and caused millions of dollars of damage. Driven by questions about how overfishing, coastal development, and climate change were contributing to a jellyfish population explosion, Juli embarked on a scientific odyssey. She traveled the globe to meet the biologists who devote their careers to jellies, hitched rides on Japanese fishing boats to see giant jellyfish in the wild, raised jellyfish in her dining room, and throughout it all marveled at the complexity of these alluring and ominous biological wonders.

Gracefully blending personal memoir with crystal-clear distillations of science, Spineless is the story of how Juli learned to navigate and ultimately embrace her ambition, her curiosity, and her passion for the natural world. She discovers that jellyfish science is more than just a quest for answers. It's a call to realize our collective responsibility for the planet we share.

Great Chew Toy
We have a Boerboel, and she destroys all toys. And I do really mean ALL toys. But Benebones hold up great! They're truly impossible to actually break. They will eventually get flaky the more they chew on them, and once they get super flaky, you'll need to replace them. But I'd say with our super chewer, who chews on them multiple times a day, we only have to replace Benebone products about once a month. These are a must have if you have a super chewer.

Well worth the money!
Spent hundreds of dollars trying to find something that would last and something my 2 Pitties would not destroy in and hour and also something they would continue to use. Search is over..

Benebone... Best dog toy!!!!!
This is my dog's fave toy hands down. The Benebone brand is the only brand of bone I buy. My dog weighs 85 pounds and can really chew on a toy and these bones hold up well. They are the best in my opinion. They have several different flavors. He likes the bacon and PB. I love how Amazon has the "buy again" option. It just makes it so easy to repurchase your items. I usually buy the "Y" shape b/c it's easy for him to hold between his paws. BUT.... Sometimes I will buy the 4 pack if I need a good deal.

No more dental cleanings!!!
I have a 68lb Pitt mix who has consistently chewed on her bone since it was delivered over 4 years ago and she has just barely chewed the nubs down. This bone is indestructible and will keep your dog’s teeth clean. Daisy is 9 years old and does not have any tartar build up and has never had a dental cleaning. She just had her check up and vet said her teeth and gums look great!! Highly recommend this for your dog!
