I Fund an interesting article on http://www.todayifoundout.com
And it reads, Today I found out “Killer Whales”, or Orcas, are actually dolphins. In fact, they are the largest member of the dolphin family, Delphinidae. Now strictly speaking, whales are marine animals of the order of Cetacea and occasionally Cetacea is used to refer to not just whales, but also porpoises and dolphins
This got my creative juices flowing and decided to resin paint the biggest whales that we know and portrait them as dolphins.
