Orcas in Moonlight

Orcas in Moonlight was created to represent the peaceful and inquisitive behaviours of killer whales.
When an orca holds their head out of the water, it is known as spyhopping. In short, it’s their way of being nosey to what’s going on around them above their ocean barrier and it’s one of my favourite orca behaviours, purely for that reason.
So why wouldn’t they want to admire the serene and untroubled waters as they dance in the moonlight?
