Whale Slaps Tail at Kayakers

Occurred on July 2016 / Kodiak, Alaska, USA

Info from Licensor: "While sailing for NOAA, we were kayaking on our off-time and were confronted by a whale feeding on nearby fish. He flipped onto his back and started thumping his tail towards us. I am still not sure if it was warning us to stay away or showing off. Truly amazing experience."
