A pod of pilot whales pose for a family portrait. "Pilot whales are incredibly special and intelligent beings that enjoy tight family bonds," says photographer Rafael Fernandez Caballero. "They are curious and territorial, so most encounters involve them coming close to see what you want. With love and respect most moments are about a unique interaction, playful moments with different members of each family. This particular picture represents one of the first encounters of that day. A whole family came together to welcome me and to make sure I wasn't a threat."
