sort of

thats what they call it

Several kinds of mollusks (squid and octopii) have tentacles with suckers.

800 is the most they can lay up to but they can lay less but they usually do not.

calamari

there are more female than male

Well, they eat stuff, so...

Learn to spell, jeez. The length of a squid is generally about 7.2634 metres.

yes

The nautilus shell is a fantastic example of sacred geometry.

What do Cephalopods eat?

Not really. It does have a hydro-skeleton where it uses pneumatic pressure to move along.

It's main mechanism of defense is intimidation. Using bioluminescent sacs on their bodies, they light up and it scares the predator away. Another method, when intimidation doesn't work, a large oval lights up, facing the anterior end of the predator. As it swims away, it also closes the tissue around the oval, making it appear smaller. This creates the effect that the squid is very quickly escaping, and the predator gives up.

No. Occasionally humans get bitten by octopuses when they handle them, but unprovoked attacks are almost unheard of. Octopuses are very shy.

There are common stories from divers in the Pacific Northwest who have been "hugged" by Giant Pacific Octopuses. They come to no harm, but you are not going to go anywhere until the octopus decided the hug is over!

Cuttlefish produce a brownish-colored ink called sepia. Cuttlefish ink was in fact where sepia first came from. The Latin name of the common cuttlefish, Sepia officinalis, reflects this fact.

yes

All you need to do is get a blob! It kills about everything!

During the day, giant squid live in the deep water. That is where they hunt deep sea fish and other squid. The live in temperate oceans, especially near continental and island slopes all over the world.

Cephalopods are found in all the oceans of the world, from warm, tropical waters to freezing, polar waters. They are found in the wave-swept intertidal zone through to the cold, dark abyss. Cuttlefish however, are usually found in temperate and tropical waters. They prefer shallow coastal waters but are also found in open oceans. During Winter, the cuttlefish gather in numbers on the shallow near-shore reefs to mate and spawn. Some species of cuttlefish swim around in schools, like other fish whereas others are more solitary and guard their own territory. The giant cuttlefish is found only in the waters off southern Australia. They inhabit reef and seagrass areas from Point Cloates in Western Australia, along the southern coast and up to New South Wales.Cephalopods are found in all the oceans of the world, from warm, tropical waters to freezing, polar waters.

Surprisingly, an octopus has neither legs nor tentacles. It has arms, which have suction cups on the underside. Most people think they have tentacles, but common octopuses do not. In fact, tentacles are merely flexible extentions. Squids and cuttlefish have such things as tentacles.

nope

The ability to camoflage and they do illusion to fish so they can eat them.

yes they actuallly do on their arms

Since cephalodpods are animals such as octopus, squid, and cuttlefish, they usually either entwine their tentacles around their prey to trap it, or they use their suction cups to stick to prey and then consume it.
