Orkanaluk is classified as a Piscine Wyvern as its features do not resemble any other sort of monster, but it is known that the creatures are mammals rather than fish. Their bodies are covered in smooth, blubbery hide that is black and white, with teal-colored horns that protrude from their foreheads. While on land, they are bipedal when walking, but often slide on their bellies for much faster locomotion. Their tail is more like a whale's than a fish's, and Orkanaluk swims like a whale because of this, its tail moving up and down to propel the wyvern. The Orkanaluk's dorsal fin is serrated for easier movement through the ice.
