A whale appears to head-butt a diver as though she's a beach ball in the ocean! The image shows the diver getting nudged as the two head towards the surface. Alex Voyer captured the stunning shots during a free-diving trip in the Indian Ocean with his wife, Marianne Aventurier. Alex said it's always incredible to see the eyes of such giants.
