One Tiny Treefrog: A Countdown to Survival

The red-eyed treefrog of the Costa Rican rain forest stars in this bold and visually arresting countdown book, which is both a captivating read-aloud and a resource.

Deep in the tropical forest of Costa Rica, ten sticky frog eggs cling to a leaf. Only nine eggs hatch. Only eight tadpoles wind up in the water below. What will it take to survive the countdown to adulthood and begin the cycle again? This beautifully designed, color-drenched introduction to frog metamorphosis peeks at this animal’s habitats and predators as it illustrates competition and natural selection. Cocreators Mackenzie Joy and Tony Piedra have crafted a dazzling spin on the life of one of nature’s darlings, the red-eyed treefrog. Back matter invites budding naturalists to discover even more treefrog facts, revisit the pages to spot other Costa Rican species, and check out a bibliography.
