Whoa! I thought their spins were just tissue. Thanks for educating me!
Most puffer fish are toxic. I found this interesting tidbit while reading about them (on Wikipedia, of course):"Dolphins have been filmed expertly handling pufferfish amongst themselves in an apparent attempt to get intoxicated or enter a trance-like state."From the citation: (https://www.smithsonianmag.com/smart-news/dolphins-seem-to-use-toxic-pufferfish-to-get-high-180948219/)"The dolphins were filmed gently playing with the puffer, passing it between each other for 20 to 30 minutes at a time, unlike the fish they had caught as prey which were swiftly torn apart.Zoologist and series producer Rob Pilley said that it was the first time dolphins had been filmed behaving this way.At one point the dolphins are seen floating just underneath the water's surface, apparently mesmerised by their own reflections."

Pufferfish skeletons are a common site on Japanese beaches. They’re usually fairly solitary but they come together for mass spawning in early summer where large groups of males compete to fertilise eggs in shallow pebble beds. As the tide goes out, some fish get stranded, leaving nearby beaches scattered with their bony shells.
