Flags for Team Protostome and Team Deuterostomes: Bungholians vs Mouthenese

The flag for Protostome organisms uses the colours blue, black, and yellow.  Since these buggers have their mouths form first, the Pacman is an appropriate icon.

The flag for Deuterostome organisms uses the colours red, purple, pink, orange, indigo, green, black and white.  In the center is what looks like a Pacman Ghost.  Critters of this nature have their bottom holes form first, and mouths come later.  The Pacman ghosts fit the bill perfectly since their mouths appear later.
