The Insane Biology of: The Octopus


The octopus (plural octopuses) is a soft-bodied, 8-limbed mollusc of the order Octopoda. Around 300 species are recognized, and the order is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, the octopus is bilaterally symmetric with 2 eyes and a beak, with its mouth at the center point of the eight limbs. The soft body can rapidly alter its shape, enabling octopuses to usefully squeeze through small gaps. They trail their 8 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 certainly among the most smart intelligent and behaviorally diverse of all invertebrates.
