The Common Octopus is found worldwide in the shallow waters of tropical, subtropical, and temperate areas, the common octopus is a fascinating creature.
At 60-90 cm (24-36 in.) long, it has eight long limbs protruding from a globe-shaped head (or mantle). Two rows of suckers line their tentacles and can sense taste.
While it was commonly believed that the octopus’s appendages were all arms, recent studies by marine experts have shown that two of the limbs act more as legs, allowing it to walk across the sea floor and push off when swimming. The octopus also has the useful ability to regenerate a tentacle if it loses one.
