Frog: A Photographic Portrait

Frog is a celebration of the fascinating range of the planet's frogs and toads. Published to coincide with Amphibian Ark's "Year of the Frog" and designed to build awareness of environmental change causing many species of amphibians to disappear at an alarming rate. The aim of the year's campaign is to generate awareness to the greatest species conservation challenge in history.

Thomas Marent, author of Rainforest (2006) and Butterfly (2008), started photographing natural history subjects, particularly birds and butterflies, in the mountains of his native Switzerland. He has dedicated nearly half his life to recording butterflies across five continents.
