"This exploration of marine animals around a coral reef is a clever blend of eye-catching pictorials and jaunty, concrete poems. Here, words curve, slant, or spike within each space, underscoring the information given in each poem, such as the way that the mysterious sea horse's curving tail ends with an actual question mark, or the way that the words describing the frogfish, a master of camouflage, are themselves camouflaged in the frogfish's coral hiding place. Readers follow two teen snorkelers, a boy and girl, as they explore the crowded sea underworld, starting with schools of fish and moving through an assortment of exquisite and downright weird-looking creatures, 19 in all, including jellyfish, needlefish, stingrays, octopuses, and spiny puffers. The snorkelers also swim to the coral reef, which contains an acrostic with a sustainability message. The information-packed illustrations--consisting of digital collage, monoprints, and screen prints--are bold but busy, often making the text difficult to read. Still, this book's playful design will likely make a splash among young readers."--Booklist.
