Did you know that the Octopus has three hearts and blue blood? They are also able to squeeze through a space as small as a pound coin, walk on land, solve simple problems, change the colour and texture of their skin and are very good at escaping from their displays!
Should an octopus be discovered it will release a cloud of black ink to obscure its attacker’s view. This will give it time to escape. The ink will also dull the attacker’s sense of smell, which will give the octopus another unfair advantage – it’ll be an awful lot more difficult to find again!
