The common octopus is unique for its appearance with its massive head, large eyes, and eight distinctive arms. But by far the most striking characteristic of the octopus is the wide array of techniques it uses to avoid or scare attackers.
Its first and most amazing line of defense is its ability to hide in plain sight. The octopus can camouflage well. When discovered, an octopus will release a cloud of black ink to dull its attacker’s view, giving it time to swim away. The ink even contains a substance that makes a predator’s sense of smell dull, making the fleeing octopus harder to track.
Octopuses are fast swimmers and can jet forward by expelling water. Their soft bodies can squeeze into small cracks and crevices where predators can’t follow. If all else fails, an octopus can lose an arm to escape a predator’s grasp and regrow it later with no permanent damage. They also have beak like jaws that can deliver a nasty bite, and venomous saliva.
The common octopus is found in the tropical and temperate waters of the world’s oceans. They can grow to about 4.3 feet in length and weigh up to 22 pounds. They prey on crabs and crayfish.
These are cool odd looking sea creatures and are almost invincible.
