Jellyfish are generally not the most loved creature in the ocean. Beachgoers fear them for their painful sting, nuclear reactor operators hate them for clogging their pipes and fisherman loathe them for decimating fisheries. But, Berwald argues there’s also a lot to like about these invertebrates. Not to mention, she believes their recent activity could tell us more about our changing oceans and global warming. Berwald enlightens us on the world of jellyfish, explains her interesting journey to write this book (which included travels around the world and making/eating jellyfish) and what the future may hold.
