Thomas Peschak is a German photographer and trained marine biologist who specializes in documenting the beauty and vulnerability of the world’s oceans, islands and coasts. We took a closer look at his story “Galapagos: Rocking the Cradle” as part of our annual collaboration with World Press Photo awards, in which we tell the stories behind the best photojournalism in the world. In the article, Thomas explained how his scientific background informs his photography. Thomas is the Director of Storytelling for the Save our Seas Foundation, and a senior fellow of the International League of Conservation Photographers. He publishes most of his stories in the National Geographic, and his TED talk about ocean conservation has been viewed more than 1 million times.
