Each day, we bring you one photo from around National Geographic that fits our criteria for Photo of the Day—sometimes classic, sometimes quirky, always an image with a story to tell. For this year’s roundup, we looked at shares, likes, and comments from the social sphere to see which ones resonated most with you. While walking along the shore of Larak, Iran—an island in the Persian Gulf—Your Shot member Pooyan Shadpoor came across the luminous scene in the photo above. The “magical lights of [the] plankton ... enchanted me so that I snapped the shot,” he writes. Many of these photos were submitted to Your Shot, our storytelling community where members can take part in photo assignments, get expert feedback, be published, and more. Join now »
