Tothtoon

The Tothtoon at present are a species of floating jellyfish with 4 broad arms, and eight tendrils, who seem to have the quirk of being appearance conscious, having once been 3-meter wide shallows-dwelling octopi, who eventual added chitinous armor shells, along with 3 other forms over their 240 million year history.

Looks aside, they are also mathematical wizards, having been exploring the subject even before being discovered and uplifted.
