These funny looking creatures are very soft and squidgy with only one hard bit – their beak.
They can fit their entire body through tiny holes so are great at working their way through mazes, and have strong suckers to hold their prey.
As active predators they need to explore, understand and remember their environment and the behaviour of other animals.
Octopi have really clever skin and can change their colour to make themselves hard to see. This is called camouflage.
They can solve problems, as when they remove a plug or unscrew a lid to get prey from a container.
