Occurred on August 17, 2017 / French Riviera, France
Info from Licensor: "On a sunny summer day of snorkeling in the south of France, a rock in the middle of the sand attracted my attention. I decided to dive and have a look and didn't see anything other than a rock and an anemone there. When I swam around, I noticed that a nice octopus tried to get invisible and metamorphose himself with the rock. It was a real pleasure to be there."
