I got silly and decided to draw mine and Mattaui's cetan characters as dolphins. They're each the dolphin they're generally based off of, but colored in the way the cetans are.

From the top, it's Merihem (Hector's Dolphin), Mattaui (Common Dolphin), Nathaniel (on the left, Spinner Dolphin), Clarisa (Striped Dolphin), Ronah (bottom left, Striped Dolphin), and Kaya (Spotted Dolphin).
