In our own juvenile stage, many of us received our wide-eyed introduction to the wonders of nature by watching the metamorphosis of swimming tadpoles into leaping frogs and toads. The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, and evolutionary biology have focused enormous attention on tadpoles. Despite this popular and scientific interest, relatively little is known about these fascinating creatures. In this indispensable reference, leading experts on tadpole biology relate what we currently know about tadpoles and what we might learn from them in the future. Tadpoles provides detailed summaries of tadpole morphology, development, behavior, ecology, and environmental physiology; explores the evolutionary consequences of the tadpole stage; synthesizes available information on their biodiversity; and presents a standardized terminology and an exhaustive literature review of tadpole biology.

Ten tiny tadpoles wriggling in a line. One went chasing dragonflies so that left ... nine. Follow the adventures of these bright, bold, 3D tadpoles in this fun and funky counting book with a surprise pop-up page at the end. -- Provided by publisher.

Tadpole loves his rainbow friend, the caterpillar, and she tells him she loves everything about him. "Promise that you will never change," she says. But as the seasons pass and he matures, his legs grow, and then his arms - and what happens to his beautiful rainbow friend? As he sits on his lily pad, digesting a butterfly, Tadpole little realises that now he will never know! Follow the predictable changes of a tadpole and a caterpillar to their natural conclusion in this award winning picture book.

Never underestimate the quick wits of 999 young frogs! “We’ll have to move,” says Mother, after realizing the pond is too small. But moving a family of 999 young frogs is fraught with danger! Hungry snakes are crawling through the grass. Hungry hawks are flying through the sky. A young frog makes a mighty tasty morsel.

Wendy Pfeffer describes the amazing metamorphosis from tiny, jellylike egg, to little fishy tadpole, to great big bullfrog. Holly Keller has created the archetypal frog pond and we see it through the seasons as the tadpoles grow legs and lungs and eventually hop onto land: bullfrogs at last. "Well-designed ink drawings washed with soft-toned watercolors stretch across the double-page spreads, showing the action above and below water level. . . .an attractive, general introduction."—BL. 1994 "Pick of the Lists" (ABA) Best Children's Science Books, 1994 (Science Books and Films)
