Lovers of marine life and connoisseurs of photography will delight in this beautifully produced book dedicated to the surprising elements of the "unseen." In Extreme Nature, National Geographic photographer Bill Curtsinger takes us to locations around the globe, from the North to the South Poles, where he reveals in amazing detail the lives of elusive water creatures-some never before photographed-and those that are ubiquitous but rarely observed close up.

Bill Curtsinger specializes in underwater subjects, he has photographed for National Geographic magazine, plus dozens of publications worldwide. Curtsinger currently lives in Maine and is a founding member of the Maine-based art group "10 x 10."
