@Great Argus These are in fact Pacific White-Sides, thank you. I was in such a hurry to upload the photos that I confused them with the spotted dolphins at the Shenzhen Safari Park.
@FunkyGibbon I saw Belugas, Indo-Pacific Humpback Dolphins and Pacific White-Sided Dolphins. I believe there are Bottlenoses at the park but I didn’t see any.
@animalman0341 Thanks. I think that in the white-sided exhibit there used to be bottlenoses and pantropical spotted. I suspect there are still bottlenoses in the arena.
