Cuttlefish are cephalopods, a class found within the phylum Mollusca. Like other cephalopods, they have bilateral symmetry, a prominent head, and their "foot" has been modified into a number of arms and tentacles. They have internalized the shell found in most mollusks, and it is referred to as the cuttlebone. Cuttlefish have no backbone; they are invertebrates, and so, despite their misleading name, they are not true fish. Protruding from around their mouths, they have eight arms and two tentacles with which they catch their prey.
One of the most remarkable aspects of cuttlefish, though, is their advanced camouflaging abilities. Cuttlefish have very complex eyes, with W-shaped pupils that can see the polarization of light and in 3-D; they are, however, colorblind. Despite this, on natural substrates, cuttlefish can change color in mere seconds to blend in so well against their background that they are hardly visible. This camouflage is done by means of a vast number of small neuromuscular organs called chromatophores that expand and contract to change the color of the cuttlefish' skin. Even after the cuttlefish has died, the chromatophores may continue to cause color-change, in a distinctive post-mortem pattern known as Wolkenwandern, or "wandering clouds". There are also some other types of cells that add to the variety of colors cuttlefish can display. Cuttlefish's sides have been likened to a tv screen, so adept are they at changing colors quickly and smoothly, and in fact, some tv screens have been developed using a technology based on cuttlefish's color-changing abilities.
the octopus can breathe through its eight legs. The eight legs have little holes in them that way the octopus breathe. Also the octopus belongs to the phylum mollusk. Octopus's are Ectothermic. And a structure for defense is they can flee very very quickly, expel ink, or use fast color changing camouflage. They eat shell fish such as clams and snails. They use there strong beak to puncture the shell of its prey and suck out the contents! Thanks you.
How does dolphins eat octopuses?
An octopus get their prey by grabbing them with there tentacles. To catch there food easier, they camoflage with the ground or rocks. An octopus get their prey by grabbing them with there tentacles. To catch there food easier, they camoflage with the ground or rocks.
How do squid travel How fast do squid travel do squid fly?
Squid use a kind of jet power. Water is squirted at great pressure out of a nozzle on the squid's body. At times the squid can swim so fast that it may pop out of the water and glide through the air at 25 to 40 miles per hour. A squid may fly for 100 feet or more before it splashes back into the water.
octopus use there mouth to feel and taste things. also, octopus only squirt ink to let his predator know that he is going to fight.
A squid does not have teeth, instead it has a very sharp beak directly in the middle of all its arms. It uses its arms to grab its food, then brings the prey to the beak where the squid tears it apart to eat it.
It's almost like a high pitched rhino noise. Something like a SQUAWCK!
What is the enemy of octopuses?
Natural predators of octopus are moray and conger eels, dolphins and sharks. - From a Google search.
No, to the most part. We do not know that much about squid and octopi simply because they live in the darkest depths of the oceans, and apparently we know more about the planet Mars than our own oceans.
Does a chambered nautilus prey on other animals?
A chambered nautilus has predators such as the octopus, triggerfish, shark and sea turtle.
No. Fish have back bones (like us). Squid are molluscs (like octopuses, snails, oysters, etc.)
How many tentacles does a cuttlefish have?
No, if you go on NOVA.com and type in cuttlefish, you can plainly see that the arms aren't as long as its body.
Phylum: Mollusca
Mollusca
A major phylum of the animal kingdom comprising an extreme diversity of external body forms (oysters, clams, chitons, snails, slugs, squid, and octopuses among others), all based on a remarkably uniform basic plan of structure and function. The phylum name is derived from mollis, meaning soft, referring to the soft body within a hard calcareous shell, which is usually diagnostic. Soft-bodied mollusks make extensive use of ciliary and mucous mechanisms in feeding, locomotion, and reproduction. Most molluscan species are readily recognizable as such.
The Mollusca constitute a successful phylum; there are probably over 110,000 living species of mollusks, a number second only to that of the phylum Arthropoda, and more than double the number of vertebrate species. More than 99% of living molluscan species belong to two classes: Gastropoda (snails) and Bivalvia. Ecologically, these two classes can make up a dominant fraction of the animal biomass in many natural communities, both marine and fresh-water.
A link to the Wikipedia article on squids is provided.
No an octopus is a mollusk, just like squids, clams, and oysters. Echinoderms are sea stars, sea urchins, sea cucumbers, sea lilies, sand dollars, basket stars, brittle stars, and feather stars.
The common cuttlefish, Sepia officinalis, has been found in the Mediterranean, North and Baltic Seas, although populations have been proposed to occur as far south as South Africa. They are found in sublittoral depths (between the low tide line and the edge of the continental shelf, to about 100 fathoms or 200 m).

The state fish (Texas Squid) is known to exist some say number in the hundreds of thousands though one has not been spotted in years. They live near oil rigs which is a natural safe habitat for the animal which produces ink for quick getaways. The Texas Squid is possibly on the endangered species list because no one knows how many there actually are. BP's recent philanthropy included dumping millions of gallons of oil into the gulf to help increase the Texas Squid population. This act was the largest act any company has done for an animal possibly on the endangered species list.
The male uses a special arm to place sperm in the female, she then lays fertilized eggs in the top of her den and she aerates and guards (and cleans) them until they hatch. She seals the den with rocks just before they hatch and as soon as they hatch, she dies.
Who covers the replacement parts for the nautilus sleep system beds?

What is the only cephalopod that has retained an external shell?
The only extant cephalopod that produces an external shell is the chambered nautilus. The shells produced by squid and cuttlefish are internal.
What do octopuses eat in the Coral reef?
Because their muscular structure is so sdvanced that they can occupy even the really small cracks in the coral. There was even one octopus that could squeeze through a hole the size of a fifty pence piece. Considering its tentacle span was about three metres, that was no mean feat!
Oh, and by the way, the plural of octopus is not octopuses. It is octopi.
