Thomas P. Peschak is an assignment photographer for National Geographic magazine and a National Geographic Explorer. He has shot eight feature stories on a range of subjects (including Manta Rays, Pipeline through Paradise, Seas of Arabia, Tale of Two Atolls, Currents of Plenty, and Return of the Seychelles). His work on "Galápagos: Life in the Balance and Stewards of the Sea" appeared in the June 2017 issue of National Geographic magazine. Originally trained as a marine biologist specializing in human–wildlife conflict, he became a wildlife photojournalist after realizing that he could have a greater conservation impact through photographs than statistics. His work now focuses on documenting some of the most critical marine and island conservation stories of our time. Thomas is a Founding/Associate Director of the Manta Trust, the former Director of Conservation for the Save our Seas Foundation, and a Senior Fellow of the International League of Conservation Photographers. He has written and photographed seven books and is a multiple winner in the BBC Wildlife Photographer of the Year and World Press Photo Awards. He is also a speaker for the National Geographic Live! Series and gave his TED talk, Dive into an Ocean Photographer’s World, at Mission Blue in 2015.
