FTA: > They live to be about four years old, with both males and females dying soon after breeding. > Highly intelligent creatures, giant Pacific octopuses have learned to open jars, mimic other octopuses, and solve mazes in lab tests. What would be the point of evolving to be so intelligent if the lifespan is so short. Seems strange to me.
