I have been known to admit that I fell in love with cephalopods because they are the closest things to aliens coexisting with us on our home planet. (I love aliens.) Clearly I am not the only person to come to this conclusion:
The giant Humboldt squid could be some sort of alien species from a 1980s science fiction film. Flashing white and red like a Klingon stealth cloak, they blanket an area to attack and devour any creature they can, including each other. They employ long tentacles covered with suckers and claw-like "teeth" to grasp their prey and bring it in to a large, hard black beak, which resembles that of a demon macaw.
