Cephalopods — octopuses, squid and cuttlefish — are some of the most fascinating creatures on Earth. Marine biologist Danna Staaf joins host Krys Boyd to discuss these intelligent and charismatic creatures and the amazing things they can do that no one else in the animal kingdom can. Her book is “The Lives of Octopuses and Their Relatives: A Natural History of Cephalopods.”
