I never knew much about squid or octopus beyond what landed on my plate. Now I am glad when I dive in the ocean I don’t encounter any of the ancient cephalopod overlords described in Squid Empire. Nasty, angry, beaked and shelled things the size of aircraft carriers once ruled the sea, and while I enjoy reading about them, Danna’s book has given me a whole new respect for Calamari fritta.
