9. They have the most oddly shaped skeletons ever.
(Photo Credit: Okoru. I think this is a clever message to humans, warning of the impending cephalopod takeover. Like putting a horse's head in our collective beds every time a dead cuttlefish washes up on the shore.)

(Photo Credit: Douga. These are Sepia mestus, or "Reaper Cuttlefish.")

20. Moping cuttlefish look an awful lot like certain Elder Gods. I don't recommend upsetsting them.
