@lance.andanova.films: They were kayaking when a humpback started tail-slapping 25 feet away. 🐋😱 Strait of Georgia BC. Calm morning. Zero warning. A 5-meter wide tail crashing into the surface with the force of a truck. Shockwave hit the kayaks before the sound did. Scientists say tail-slapping sends sound waves miles through the ocean. The whale was not threatening them. It was just talking. Very loudly. Follow for daily encounters. 🌊 #humpbackwhale #kayaking #whaleencounter #fyp #WildlifeDocumentary
