It may be an infuriating puzzle which has baffled and defeated countless children and their parents over more than two decades, but this octopus appears determined to solve the Rubik’s Cube.
The three-dimensional puzzle, which became a huge success in the early 1980s, is among toys being given to the intelligent sea creatures to determine whether they favour a particular tentacle, or if they are octidextrous.
Studies are also being performed to see if octopi experience frustration and annoyance with the Rubik’s Cube, and whether or not they resort to peeling the stickers off in order to “solve” the puzzle.
