What a# powerful blow! Epic footage of this massive humpback whale off the coast of Australia!🙌🐋🔥 When a whale “blows,” it’s exhaling air, not water, from its blowhole. This forceful exhalation creates a visible spout or spray of condensed water vapor, mucus, and oils, which can be seen from a distance. The shape and size of the spout can even help scientists identify different whale species. . . 🎥 @hover_images . . . #cetaceans #whales #humpbackwhales #dronevideography #whalewatching #austr
