Aquilon and Surf

Aquilon is an orca dragon hybrid. He lives in Antarctica with his companion Surf. Aquilon hunts fish, seabirds and occasionally sea leopards. He has a blowhole on his head between the horns. He can also get out of the water for some time but he doesn't like it and doesn't do it if not absolutely necessary, also because Surf needs to stay in the water. Aquilon is about four meters long, which makes him significantly smaller than an orca. He cares a lot about Surf and would do anything for him. 

Surf accompanies Aquilon wherever he swims. He's no ordinary orca, he has patterns similar to Aquilon and he's only a meter long even though he's fully grown. Surf never had a pod but he is able to communicate with Aquilon and they keep each other company. Sometimes Aquilon floats on the surface of the water and Surf rests on his back, right behind the dorsal fin. It also happens that Aquilon swims with his head out of the water and Surf rides the bow wave.
