(1) K-3 "What if your body could make its own light?" In Kuo's gorgeous exploration of bioluminescence, an adult and child encounter organisms that do just that in the air, sea, and underground. The black-backgrounded illustrations creatively employ negative space and a limited palette--almost exclusively blue, orange, tan, and white--to produce images that effectively capture the subdued glow of bioluminescent life. At first, the human pair appears in the illustrations alongside fireflies, foxfire, glowworms, and dinoflagellates, all of which live in locations people can visit. Kuo then invites the two (and readers) to "just imagine..." what it's like deep in the ocean where bioluminescent animals live, where their light helps vampire squid scare their enemies, dragonfish find food, and jeweled squid camouflage themselves. The poetic main text, which encourages observation and wonder, is accompanied by short paragraphs, in a smaller font, that present factual information about the featured organisms. The final pages issue a gentle warning that human-caused light pollution is making this amazing phenomenon increasingly difficult to see.

(1) YA In this wide-ranging, amusing, and informative investigation of the insect world, Maloney features the ways in which insects are remarkable unto themselves as well as in relation to humans and the environment. The book opens with a chapter on the basics of insect anatomy and characteristics, with plenty of examples to illustrate their remarkable diversity, then turns to chapters that center on particular insect themes and meander into related topics. A chapter on the role of insects in decomposition includes discussions about forensic entomology, poop-eating dung beetles, and an escapade involving deer skull scavenging, for example. Maloney herself is the central character: an enthusiastic, unflinching, and unfailingly curious explorer of all things insect. She cooks with cricket flour; mail-orders painted lady butterflies, hissing cockroaches, and an ant farm; conducts citizen science insect counts in her own backyard; and interviews scientists to gather information about cutting-edge insect investigation. Her friendly, engaging text includes many analogies (exoskeletons as "the ultimate power suit") and jokey asides. Interspersed throughout are spot illustrations of insects that combine field-study precision for the bodies with large cartoonlike eyes and expressions. If readers are not already inspired by Maloney's antics, the final chapter provides an exhaustive list of ways to take action and preserve insect species. A suggested reading list and an index (unseen) are appended.

(2) K-3 Illustrated by Chris Sasaki. "Did you know the natural world is a construction zone? Whether they are large or small, in the ocean or on land, animals are amazing architects!" Cherrix (In the Shadow of the Moon, rev. 3/21) explores a number of structures that animals build for shelter, for defense, or to obtain food. Coral reefs, nests of twigs and stones, spider webs, and underground homes for ants and prairie dogs are some of the structures described in short paragraph-and-illustration sequences that unfold across four-page sections. The first pages of each section show in-progress construction of the structure; then the final product is revealed through a sentence split across the page-turn ("As the burrow expands, it becomes... / ...a [prairie] dog town"). Sasaki's (Home Is a Window, rev. 3/19; Paper Son, rev. 11/19) thoughtful illustrations use a variety of perspectives to follow the animals as they gather materials or dig above- and underground, and to allow viewers to look up, down, and through the creatures' creations to see how they're used. Some of the structures, such as nests, are built by solo animals for their personal use; others are constructed by social groups for the benefit of the collective. Many structures also benefit other species in their respective ecosystems, such as the coral reef, which provides shelter for multitudes of ocean dwellers, and the beaver dam, which produces a "brand-new pond that every animal in the forest will enjoy." A list of selected sources is appended.

(3) 4-6 The table of contents gives readers a taste (ew) of what's in store: poop, mucus, spit, gas, and more. Eamer goes beyond the gross hook, however, explaining in an introduction, "Many of these animals actually survive on revolting substances and thrive on gross habits." A lively and accessible page design includes close-up photos, text boxes, and design elements to up the ick-factor. Eamer's detailed text strikes the right balance between intriguingly disgusting facts (hagfish produce slime "by the bucketful in less than a second") and solid information (scientists are looking at using "hagfish slime as a natural replacement for petroleum-based fibers"). "Some gross extras," a glossary, selected sources, and an index conclude this well-organized offering.

(2) K-3 For some animal species, there are evolutionary advantages to social groupings. "Packs, herds, huddles, and pods. Together, we are better." Salyer introduces young readers to many of the creative words used to describe animal aggregations (an army of frogs, a flamboyance of flamingos, an ­implausibility of wildebeest) but also explains just what those groupings provide: care for their young (elephants, lions); communication to locate food and prey (bats, bees); and safety in numbers (zebras, mongooses). The richly colored illustrations portray the multitudes, often oriented to seem to flow past the observer, or to highlight how animals clustered together make it hard to identify individuals or distinguish them from their backgrounds. The final double-page spread connects the book's message to a familiar social animal--humans--as people of all ages, genders, and ethnicities happily congregate in a village square. "All together...we are better!" Notes at the end of the book identify the exact species portrayed in the illustrations, and caution that many of these species are under threat of extinction. Also appended with a brief bibliography.

(2) K-3 Illustrated by Bert Kitchen. Buhrman-Deever imagines the relationships between predators and prey as poetic standoffs. Animal antagonists express their behaviors and needs in a variety of creative poetic formats. Content and cadence are cleverly aligned with the actual behaviors of the animals, and the structure and layouts of the poems also echo traits of the creatures. Illustrations are in soft focus, with stippled green and brown landscapes. Bib.

(4) 4-6 Illustrated by Mike Shiell. Where there's a stink, there's bound to be something disgusting--that's the charm of this book about the olfactory senses of humans and animals. From rotting flesh to poop to skunk spray, readers learn about many aspects of smell. Cartoony caricature illustrations add to the kid-appeal. The fonts of the chapter titles and subject headings are close enough to make the organization a little confusing. Glos., ind.

(3) 4-6 Arnosky explains how the showy appearances or behaviors of animals help them to find mates, scare off predators, and communicate. His excellent illustrations, some across foldout pages, include dramatic portrayals of animals in full display as well as smaller sketches that provide variations across species. Personal notes from the naturalist author-illustrator at the beginning and end add an intimate touch. Reading list.

(3) K-3 Illustrated by Britta Teckentrup. Unlike the other chameleons, Leon can't seem to change color to match his surroundings. Readers are interactively encouraged to count, whisper, smile, and more as neon-orange Leon searches for an environment (green jungle? yellow desert?) in which his brilliant glow will fit. Teckentrup's bold digital illustrations play with variations in shade and texture, demonstrating the many ways an animal can blend in--or not, in Leon's case.

(2) K-3 The fourth book in this "seriously funny" animal series follows the same winning formula, this time discussing elephants. The conversational main narrative--covering the two main elephant types, plus their diet, behavior, and defenses--is supported by text boxes, signs, and speech bubbles in which elephants and others offer additional facts and advance a silly subplot. The welcoming cartoon illustrations also effectively balance educating with entertaining. Reading list.

Such actions are on display in Jenkins's crisp paper-collage art against white backgrounds. More information on each animal is appended. Reading list, websites.

In the voice of each animal (goat: "I've got OBLONG eyes"), the text is simple but introduces some interesting vocabulary; the bold, clear illustrations give close-ups of the different eyes.
