OK, maybe I overstated it a little, but not by much, according to this New York Times article. Mexican shrimp fisherman call the squid (Humboldt squid, officially) "red devils" due to their pink skin color and their aggressive nature.
Don't believe it? Check out the video below.
My theory is that the giant flying squid have had enough of what the humans are doing to their waters and their prey, and are fighting back.
Or, they're auditioning for the next SyFy "A vs B" movie.
