One large one and one smaller one. They were playing around. The small one would jump out of the water.
The large one would smash it’s tail onto the water making a thunderous sound. At one point as they swam a bit further out into the bay the large one smashed it’s tail onto the water twelve times in a row. It then came up for air. It was a loud sound like thunder each time.
Quite impressive. We were so into it we did not think to take a video until they were farther out of the bay. We are thinking a mother and her calf?
