Where is the octopus?

The octopus is most active at night. During the day, it prefers to hide among the rocks where it sits completely still. It is therefore not always easy to catch sight of our Mediterranean octopus – can you see where it is hiding?

Super suction cups

With its soft but strong suction cups, the common octopus feels and tastes its surroundings. It uses the suction cups to locate prey in cracks and crevices.

Sharp vision

The common octopus has excellent vision. It can see just as well as cats do, but it cannot see colours. It sees its surroundings in black and white.

Learns easily

Compared with other invertebrates, the common octopus has a highly developed brain. It can learn to recognise symbols, find its way through labyrinths, and open jam jars.

Blue blood and three hearts

The common octopus's blood is blue because it contains copper. Our blood is red – it contains iron. The common octopus has 3 hearts, which enable it to pump blood quickly to its many arms.
