All species within family Planorbidae have sinistral shells.
gollark: Actually, you can, but only in bizarrely specific ways.
gollark: Well, consciousness/abstract reasoning/etc.
gollark: "You" are some specific brain modules which handle consciousness and language and whatever; it's hardly guaranteed that you have write access to everything else.
