National Geographic : 1971 Dec
Popping a cork for lunch, a female briareus named Lee demonstrates the ingenuity of octopuses, which join with squids in having the most com plex brains of all invertebrates. Lab oratory raised from the clutch on page 783, Lee became the first octopus trained to open a bottle. Enticed by a shrimp, Lee snakes an exploratory arm around the cork (left), then drapes herself over the plug, grasps it with the bases of two arms, and slowly rocks it out (top). She then reached in for the snack. Lee often crawled inside the 81/2 inch-long bottle as photographer Sis son tried to rebait it (above), almost KODACHROMES © N.G.S. as if to say, "No tricks this time. Now that I'm in your silly jar, let's have the food!" Mr. Sisson, who designed the jar, put in a shrimp, and first offered the container to Lee without a cork. Tem porarily baffled by the clear glass, Lee soon learned that the hole was her only entrance. The photographer gradually trained her to remove the cork by putting it askew atop the hole, and then in it. Eventually the octopus learned to remove the cork after it had been pressed tight, setting a ten minute record.
