The Secrets of the ­Jellies: Amazing Jellyfish and Their Surprising ­Talents

K-Gr 3–Inspired by the Monterey Bay Aquarium and its amazing exhibit, this book offers a captivating exploration of ­jellyfish, presenting these creatures as stars of the ocean. The text details the amazing ­jellyfish and their surprising talents through a mix of lyrical verse and robust back matter. Readers learn that jellies are invertebrates with gelatinous bodies composed of about 95 percent water, and, perhaps surprisingly, they possess no bones or brains. The content covers the vast diversity of true jellies that come in a dazzling mix of shapes and sizes, from the tiny thimble jellyfish to the lion’s mane jellyfish. Complex concepts like their unique anatomy, life cycles, and methods of self-propulsion using contracting subumbrella muscles are explained. Additionally, the book covers fascinating facts, such as how many species are bioluminescent and radiate a blue-green glow in the darkest depths of the ocean to lure prey or startle predators. Hermansson’s illustrations, rendered digitally and beautifully complement the vibrant subject matter, showcasing the creatures in various colors and hues. The artwork includes informative diagrams that help explain complex biology, such as how jellies live and move despite lacking a brain. Her hand lettering also contributes to the design. The combination of engaging, poetic text and well-supported scientific details makes this an educational yet visually appealing title.
