Dr. David Scheel, a professor of marine biology at Alaska Pacific University in Anchorage, raises a day octopus in a tank in his home with assistance from his teenage daughter Laurel. Given the name Heidi, the octopus bonds with the Scheels, showing recognition of their faces, excitement when the humans come near and an inclination for playing with Laurel. Scheel links his discoveries — which also include Heidi’s demonstrated abilities to change color, solve puzzles, use tools and escape through small spaces — to octopus findings from all over the world, further proving the extraordinary intelligence of these incredible creatures.
