Octopus from Smartest Animals in The World

Although still not explored enough, octopus is one of the smartest inhabitants of the sea. Octopus is an excellent hunter due to its secret weapon-an ink bag which is hidden inside its body. When faced with the enemy it releases the ink to confuse the opponent, and it also releases the substance that numbs the sense of smell, so the opponents are not able to feel its presence. It has a fantastic short-term memory, it can solve problems, it can play and change its body color to match the color of seabed.
