Whale Shark, New Guinea

Photograph by Michael Aw

"Suddenly he just jumped in!" says photographer Michael Aw. Sarmin Tangadji, the Papua police officer who escorted the photographic team to where the sharks congregate, "was so excited to see them up close." Aw shares that excitement when it comes to diving with a dozen whale sharks: "You are sandwiched in, sharks ahead and behind, but you want to be there," he says. "They make eye contact with you and then charge by. It blows your mind."
