Great photos.
A few years ago, an Orca hunted and killed a Great White. In the Pacific near Gay Frisco. The youtube link below is similar to how the Dolphin became the main encore.

It was reported Great Whites left the N California area and headed south.
The clip didn’t mention that the Great White was stalking the Orca’s baby, and the Orca just retaliated protecting it’s young one.
A great white flipped on its back goes to sleep. Well, I learned something new today.
