This week, our field staff sent dazzling close-ups of some of the biggest animals we encounter, on land and on sea. In Alaska and the Arctic, brown bears and polar bears were the stars of the week on land, and guests spotted numerous humpback whales in the water. And in the Galápagos, a visit to Santa Cruz Island yielded photos of the islands' most iconic creatures: giant tortoises. Get Inspired By Photos, Videos, Webinars, Stories, And Exclusive Offers.
