The Satellite

Winning first place, Francesco Visintin captured this image at Forte dei Marmi, in Tuscany Italy. Several factors including rising sea temperatures, mating season, a decrease in natural predators as well as winds and currents concentrated thousands of jellyfishes off the Versilia coast. The photographer, inspired by the calm sea and clear waters, made use of the soft light of the early mornings and sunsets to capture these images. (Credit: Francesco Visintin)

Taking third place with this portrait of a humpback whale calf, the photographer took a chance and risked capturing no images by following his gut and diving in a cove off San Benedicto Island at the Archipeilago Revillagigedo, Mexico, which was not on the agenda. His risk paid off with this proof of his "magnificent encounter." (Credit: Gregory Sherman)
