About the Holiday
This month’s observance pays tribute to the role of zoos and aquariums and the work they do for education, conservation, and research to protect the world’s animals. Through interactive and hands-on programs, zoos and aquariums provide visitors with up-close experiences in which they can learn about the environments and science of each amazing creature. These institutions are also reaching out with personal and online visits to schools by zoologists and other experts, increasing the interest in biology and animal science to students. To celebrate, plan a visit to your local zoo or aquarium—or make it a “must see” of any vacation!
Thanks to Chronicle Books and Barbara Fisch of Blue Slip Media for sending me a copy of this beautiful book for review!
The Secrets of the Jellies: Amazing Jellyfish and Their Surprising Talents
Written by Karen Jameson | Illustrated by Marie Hermansson
It’s impossible not to be fascinated by jellyfish. We’re captivated by their beauty and grace and can’t help but admire their defensive subterfuge—as long as we’re not on the receiving end! In her lyrical nonfiction picture book, Karen Jameson reveals intriguing facts about these dazzling underwater creatures that can be found in every ocean zone, from the shallows to the deepest recesses. She celebrates “see-through jellies, bright ones, too—colors in each shade and hue! / And in the darkness, down below, they radiate a blue-green glow!”
Jellies bioluminescence is only part of their charm, however. We marvel as we watch jellyfish seemingly glide effortlessly through the water, wondering, “how do they do that?” Jameson has the answer, not only to how they propel themselves, but also to how “jellies live without a brain,” how they reproduce, how they satisfy their hunger, and even how other sea creatures befriend jellies for their own survival.
You might think that by just bobbing along, jellyfish would be easy prey, but Jameson reassures readers that “jellies hide, jellies dodge with super-sneaky camouflage! / In the depths or close to shores, they stay away from predators!” With such smarts and agility, it’s no wonder the sea blooms with “jellies here, jellies there—hundreds, thousands everywhere!” or that “we’ll study them for years to come, these stars of the aquarium!”
Extensive back matter follows the story, with a section on Jellyfish Facts that explains more about the number of “true jellies” around the world, information on the smallest and largest jellyfish, their bioluminescent properties, how they move, how they “think,” their life cycle, diet, predators, groupies, and jellyfish blooms. Readers also learn about how aquariums care for their jellyfish, their role in the ocean’s ecosystem, how they sting, and how climate change affects them. In a paragraph on current jellyfish research, children are invited to become citizen scientists and track jellyfish through a provided website link. Children are next introduced to 22 types of jellyfish that they will then enjoy finding throughout the book.
Readers will happily glide along with the incredible jellyfish Karen Jameson introduces through her perfectly rhyming and rhythmic storytelling that educates while also providing the fun of an interactive read-aloud. Excitement builds as the verses flow toward the final rhyming word, which kids will be eager to call out as they engage with Jameson’s clever learning experience. In her conversational back matter, Jameson explains jellyfish facts and features in clear terms, using examples and vocabulary that resonates with her young audience. Each paragraph offers fascinating information to spur further research for classroom or homeschool cross-curricular assignments.
Marie Hermansson’s vibrant lifelike digital illustrations float and swirl with the motion of jellies, transporting readers under the ocean to witness the variety of shapes, colors, and sizes of these aquatic marvels. Scientific concepts, such as jellies’ propulsion and nerve net, are clearly portrayed to enhance understanding. The endpapers give kids a glimpse of the Monterey Aquarium, whose jellyfish exhibits inspired this book.
Shimmering with the magic and mystery of jellyfish, The Secrets of the Jellies: Amazing Jellyfish and Their Surprising Talents is scintillating nonfiction at its best. The book is a must for any public, school, or classroom library collection and an exciting addition to home bookshelves for any child fascinated with the ocean or marine biology.
