Octopus have the most highly developed brain and eyes among invertebrates. Their eyes, like ours, can be finely focused and can adapt to changes in light. The optic lobe interprets information received from the eyes and this, along with an acute sense of touch, enables an octopus to make surprising clever decisions.
Many scientists report seeing an octopus learn to remove a stopper from a bottle in order to reach crustacean inside. Others have reported that an octopus can figure out how to unscrew the lid on a jar in order to get at the food within.
Regarding the cleverness of the octopus, the bookExploring the Secrets of Natureconcludes; "We are inclined to credit Primates with the highest levels of intelligence, but there is proof that octopuses, too, are among the most intelligence of animals".
No wonder that the world football body (FIFA) in 2010 world cup hosted by South Africa made use of predictions from this chameleon in all the matches of the competition, and majority of its predictions were true.
