Thanks for pointing it out, I didn't know that orcas are dolphins too. The one I saw was like a "bottlenose dolphin" with the classic dolphin shape and color.
> The orca, or killer whale, is a toothed whale that is the largest member of the oceanic dolphin family.
> Oceanic dolphins include several big species whose common names contain "whale" rather than "dolphin", such as the round-headed whales including the false killer whale and pilot whale). The Delphinidae family also includes the porpoise, beluga whale, and narwhal.
