The octopus is a soft-bodied, eight-limbed mollusc of the order Octopoda. Around 300 species are recognised and the order is grouped within the class Cephalopoda with squids, cuttlefish and nautiloids. Like other cephalopods, the octopus is bilaterally symmetric with two eyes and a beak, with its mouth at the centre point of the eight limbs (traditionally called "arms", sometimes mistakenly called "tentacles"). The soft body can rapidly alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates.

Appearance

Octopi have 8 tentacles and an oval-shaped head. They are naturally red, but can change color like a Panther chameleon. If you flip one over, you will discover a small black beak.

Activity

They have the ability to squeeze into small spaces such as empty jam jars. Their tentacles can grip a wide variety of surfaces, such as boat hulls. They eat their food with a small black beak.
