"This image was shot during my first encounter with orcas in the Sea of Cortez," says photographer Nicolas Hahn. "These magnificent animals cruised past me at a relaxed pace. Playfully, the calf turned upside down and showed its white belly. Witnessing the close bond between mother and calf in the fathomless ocean was a powerful and emotional experience. It is my hope as a photographer that capturing and sharing moments like these can transmit some of the rich feelings that this sight originally evoked."
