Honorable Mention - Sean Steiniger, Ha‘Apai Island Chain, Tonga
"A humpback whale calf sails through the emerald-blue waters of Tonga, closely accompanied by its colossal mother and escort. As the leviathans circle directly beneath me, the calf ascends toward the surface for fresh air. I tuck back my freediving fins and snap the shot. A split second later, momma surfaces to usher her baby away from the bubble-blowing stranger."
