They are far more to us than a springtime chorus of croaks and peeps. Frogs are essential to several key ecosystems; they are also a leading indicator of the rate of species extinctions and the health of our planet. In 2010, conservationist and wildlife photographer Robin Moore spearheaded the Search for Lost Frogs campaign, coordinating teams on five continents to find frogs, toads, and salamanders that had not been seen in decades. Illustrated with exquisite close-up photos that capture the frogs' remarkable coloring and camouflage, and reveal their often diminutive size, this book follows Moore and his colleagues as they trudge through rainforest, climb mountains, and paddle rivers across Haiti and Colombia in search of elusive creatures like the orange-and-black Variable Harlequin Frog of Costa Rica.

"We've lost 52 percent the planet's wildlife in the past 40 years, and while it's easy to raise awareness of, say, the plight of the polar bear, it is far harder to make people care about frogs. [Moore] relies upon more than eye-catching photographs to convince people that amphibians are worthy of our protection. He's wrapped 70,000 words around his 400 photographs, sharing the wonder of the animals and explaining the vital role they play in countless ecosystems."—Wired

"The (Search for Lost Frogs) campaign was wildly successful. In a year, scientists in froggy parts of the world found 20 of the 'lost' frogs—one of which had last been seen in 1874. Frogs got more media scrutiny than at any time since Noah's Ark. And now Mr. Moore has written an excellent account of the campaign—full of passionate scientists, wild landscapes and exquisite pictures of these luminous creatures that for once are getting the attention they deserve."—Economist (London)
