This is a Commerson's Dolphin, also known as a Panda Dolphin. The decors on this animal are outstanding indeed. It looks a bit like another Delphinidae family member, the Orca.

This is one of the smallest dolphins out there and even though scientists do not know why, but they swim upside down when in groups. They think that it is for better visual inspection for predators.

I loved it when I first saw it and just had to make one, a 10 meter version to be precise.
