“A large, inquisitive, and almost dangerously playful female humpback whale calf measures

“A large, inquisitive, and almost dangerously playful female humpback whale calf measures me with her pectoral fin,” explains Matthew Draper, who took this photo in Tonga. “This image was captured on a very wide fish-eye lens, which doesn’t quite show how close she really is. By measuring how close I am she can determine if her tail is going to come in contact with me as she swims past.”
