There is nothing more wonderful than meeting a marine turtle while diving in the ocean. A lucky guy encounters a curious green turtle when he is diving in the Moore Reef, which is part of the Great Barrier Reef in Australia. /VCG Photo

The green turtle spotted its reflection in a diver’s mask and even stopped to take a closer look, mistaking its reflection for another phrator. /VCG Photo
