#OCTOPUS ANATOMY HOW TO#
Octopi have great problem-solving skills and can often figure out how to escape even the most secure fish tanks.The octopus preys on crabs, crayfish, and mollusks, and will sometimes use their ink to disorient their victims before attacking.Some octopi will collect crustacean shells and other objects to construct fortresses, or “gardens,” around their lairs.The saliva of the octopus contains venom, which makes it poisonous. The octopus also has beaklike jaws that can deliver a nasty bite.If the octopus is caught, it can give up an arm to the predator and grow it back. The body of the octopus can also squeeze through very small cracks, which helps them to escape a situation that is threatening.The octopus can also blend into its surroundings, which allows it to hide from predators. The ink also dulls the predator’s sense of smell, which makes it harder to find the fleeing octopus. The octopus can also protect itself by squirting an inky substance at a predator, temporarily blinding it.If they are threatened by a predator, they will force water out of this tube with a great deal of force, almost as if they have jet propulsion. The force of the water will send the octopus backwards very quickly. The octopus moves by forcing water out of its body through a tube.

The female guards her future offspring the entire time. When a female octopus lays eggs, it takes about a month for the eggs to mature and hatch.The largest one caught weighed 600 pounds and its tentacles spanned 33 feet. The Giant Pacific Octopus lives in the coastal waters off of British Columbia and is the largest octopus in the world.The octopus can grow to about 4.3 feet (1.3 meters) in length and weigh up to 22 pounds (10 kilograms), although the average octopus is much smaller.The octopus is considered the most intelligent of all the invertebrates.The octopus has excellent eyesight but poor hearing (between 400Hz and 1000Hz).The arms also have many nerves which allow the octopus to grab and taste things.
