Octopus

The octopus belongs to the phylum, Mollusca. It shares this phylum with its brethren squid and mollusks. It is a cephalopod, the octopus; therefore, Cephalopoda would be its class. Hope this helps.

There are a few things that eat octopi, but mainly the common enemy would be a shark. Octopi are not dumb however, and they're well-versed with defenses that can help keep a shark at bay. It was actually observed in an Aquarium that an Octopus purposely assassinated every shark in its tank, without consuming them. It's speculated that it did this to make sure it didn't get eaten.

Well, the octopus had ink glands like the squid, and if it had fins then not only would it look ridiculous, they couldn't get away from predators. Also, on a octopuses tentacles, there are suction cups. They can't get them on fins, and they work as hands.

I think octopuses and tenctacles get along, not fins. Don't you?

it has an eight legs

They have no shell but yes they are technically shellfish. If you have a shellfish allergy you can't eat octopus.

the dumbo octopus got its name from the Disney character dumbo. because it has two ear like fins at the top of its head that they use for swimming to get away from its enemies.

no. calamari is actually squid, and squid is not a type of octopus.

if another animal eats it or the leg falls of from something else yes.. but it grows back =P

In addition to having adaptable and ingenious camofluage, octopuses (as well as most cephalopods) can squirt an infamous "ink" from a special glandular pouch to enable their escape. The ink is actually melanin, the same pigment that determines how dark or light a human's skin tone is. Some species of deep-ocean octopus actually produce a bio-luminescent ink.

which animal is a octopus interdependent with.

Black so that it could dissappear!

As octopuses are amung phylum Cephalopoda and are not vertebrates or its sub phylum mamalia ie mammals give live birth the octupus lays eggs

It is Called Octomeat

I DONT KNOW THATS WAT I AM TRYING TO FIND OUT -.-"

Jellyfish are simply collections of biological cells with no brain and no circulation. There are no genders of jellyfish (like man or woman). Some have the protection of releasing a stinging liquid when they are brushed up against.

Octopods are much higher-order animals having an eye, a beak, 8 tentacles that can be as gentle as a breeze, or as strong as a brute. Octopods are actually very intelligent, and can work out solution to puzzling situations.

Octopods can protect themselves from enemies by releasing a cloud of brownish "ink" that is uncomfortable to the predator, meanwhile hiding the octopod while he/she escapes.

Another protection of many octopods is their strange ability to change color and pattern, and to change shape to match the ocean floor where they currently are, as well as arranging their tentacles in shapes that predators take for a dangerous fish of some kind. Octopods are amazing creatures and range from thumbnail size up to the giant 30-foot species.

Octopi are ambush predators who wait for fish to swim close enough to be captured in its tenacles. Once captured the fish is drawn to its mouth and beak which are on the underside center of its body where it is devoured.

When an octopus is alarmed, it squirts ink at its predator to blind it momentarily while it escapes.

Blacktail Damselfish (Dascyllus melanurus)

Octopuses use a special form of sexual reproduction. The male octopus uses a specialized arm called a hectocotylus to transfer sperm to the mantle cavity of a receptive female. The female lays strings of fertilized eggs on the roof of her den. She guards, cleans and aerates the eggs with water expelled from her siphon until hatching-anywhere from 30 days to a year, depending on the species. The female may build a wall of rocks to seal off the den and will remain in the den until just before she dies, after the eggs have hatched. Squids often mate in large groups, and attach their egg capsules to the ocean floor or to seaweed. Most adult octopuses and squid die after reproducing. Their bodies are recycled in the food web, nourishing other animals, and ultimately providing food for their young when they hatch.

Octopi and SQUIDS rely on naturally generated- its a bodily fluid like blood or semen, Sepia, which is also used for the ink tone familiar to artists and photographers. the Cephalopods- octopi and squids use it as a form of camouflage device akin to a smoke screen, possibly an odoriferous one at that. sepia film was still made for portrait work by Land Polaroid ( by the way the name of the inventor not its intended usage- there is no Marine or Air polaroid) as recently as 200l according to Shutterbug annuals. Movie actresses look good in sepia like Gina Lollobrigida and Ronnie Spector the singer.

they dont have the sense of touch but they can sense chemicals, to smell or taste.

no

1. Ink jet dispersed into the water as it flees.

2. Changing the color and texture of their skin to blend in with their surroundings to avoid predators.

A female octopus will only mate once. A female will mate with (obviously) a male, she will then lay her eggs in a den. She will not leave the den until the eggs have hatch. By the time the eggs hatch, the female will have died of starvation.

They use their beak and spit some posion out from their beak. Their tentacles grab hold tightly on to their prey. The most dangerous octopus is the Australian Blue-ringed Octopus (it has the posin to kill a person).
