*Junior Library Guild Selection 2017* Only a few dozen vertebrate animals have evolved true gliding abilities, but they include an astonishing variety of mammals, reptiles, and amphibians. North America’s flying squirrels and Australia’s sugar gliders notwithstanding, the vast majority of them live in rainforests. Illustrated with arresting photographs, Catching Air takes us around the world to meet these animals, learn why so many gliders live in Southeast Asia, and find out why this gravity-defying ability has evolved in Draco lizards, snakes, and frogs as well as mammals. Why do gliders stop short of flying, how did bats make that final leap, and how did Homo sapiens bypass evolution to glide via wingsuits and hang gliders—or is that evolution in another guise?

KIRKUS STARRED REVIEW 2020 Outstanding Science Trade List A Junior Library Guild Selection Natural selection and speciation are all but ignored in children’s nonfiction. To help address this glaring deficiency, award-winning children’s science writer Sneed Collard traveled to the Galapagos Islands to see for himself, where Charles Darwin saw, how new species form. The result is this fascinating story of two species of iguana, one land-based and one marine, both of which developed from a single ancestor that reached the islands millions of years ago. The animals evolved in different directions while living within sight of one another. How is that possible? Collard uses the iguanas to explore Charles Darwin’s great discovery. F&P Level V

* School Library Journal Starred Review * * Honor Book SSLI (Society of School Librarians International) * *Skipping Stones Honor Book* Fish that live in tropical seas are like city dwellers, packed into reefs and surrounded by life in great variety and urgent motion,Fish that live in tropical seas are like city dwellers, packed into reefs andsurrounded by life in great variety and urgent motion, day and night. Through color, shape,size, and other adaptations, city fish and country fish have evolved to survive in their particular habitats.In City Fish, Country Fish, Mary Cerullo uses this powerful analogy and Jeffrey Rotman’s vibrant underwater photos to captivate young readers with the wild variety of ocean life. The second edition of this popular book includes new information about the effects of climate change on fish and their habitats and about great white sharks, who are among the few species who roam back and forth between cold and tropical waters.

The role of venoms in nature … and in human medicine Why are toxins so advantageous to their possessors as to evolve over and over again? What is it about watery environments that favors so many venomous creatures? Marine biologist Paul Erickson explores these and other questions with astounding images from Andrew Martinez and other top underwater photographers. GREAT for teaching STEM Marine Biology Scorpions and brown recluse spiders are fine as far as they go, but if you want daily contact with venomous creatures, the ocean is the place to be. Blue-ringed octopi, stony corals, sea jellies, stonefish, lionfish, poison-fanged blennies, stingrays, cone snails, blind remipedes, fire urchins—you can choose your poison in the ocean. Venoms are often but not always defensive weapons. The banded sea krait, an aquatic snake, wriggles into undersea caves to prey on vicious moray eels, killing them with one of the world’s most deadly neurotoxins, which it injects through fangs that resemble hypodermic needles.
