If you ever thought that jellyfish was beautiful (rather than disgusting and likely to sting you), you will love Spineless: The Science of Jellyfish and the Art of Growing a Backbone. Did you know that jellyfish can clog desalination plants? That fishermen in Georgia send their jellyfish catch to China? That many jellyfish have a two-stage lifecycle, and some can actually return to an earlier stage? That box jellies have six eyes, each with specialized characteristics? They are amazing, and still poorly known creatures. I could have done with fewer details on the author’s personal life, but they were written endearingly.
