A little bit more information about Aquatians: Instead of belly buttons, Aquatians have a slit that runs down their stomach. Since Aquatians view belly buttons as ugly (noses, too, but humans have highly visible noses), they tend to skip out on adding belly buttons to their human form. Also Aquatians always refer to themselves by family name first (typically a color) followed by their given name. Aquatians like to craft names which turn into other color related words or phrases when said together. Blue Skye, Seafoam Greene, and Burnt Sienna are all examples of more common Aquatian names.
