Squid

Squids have two long tentacles to help grasp food, they squirt ink so they can escape from enemies, they use bio-luminescence to get light and they can change colors.

The squid can shoot out ink from its siphan (water jet) to blind its enemy. This siphan comes of the mantel (body) of the squid and is also used to suck in and expel water for respiration, and propel themselves through the water. Its axons are very large and therefore have become a prime target for neurological studies. Some giant squids may have the ability to become luminescent (glow) through the use of chemicals (like many smaller sized squids). Two unique things about giant squid are that they have very large eyes compared to most other animals. They also have an unusual amount of ammonium ions in their circulation allowing them to maintain a buoyancy close to that of the water so that they do not get crushed from the ocean pressure or sink.

It will die

Yep it

Will

Die

Yes although,
It will take a couple of months but the limb will be fully functional again once its completely done.

The octopus is an invertebrate, therefore it cannot be a fish, which belong to the group of animals known as vertebrates.

The octopus is a mollusc, and from the same group as squid and cuttlefish.

20,000 to 100,000 eggs... and overproduction would be over 120,00

8 if you don't count the 2 tentacles which are for eating.

Octopuses or octopi can live in many places in the marine biome also they can live in the saltwater, shallow water and the pelagic zone which could be considered in the Atlantic Ocean or the Pacific Ocean. Technically all the oceans you can think of and the oceans you think they could survive in.

A squid is ectotherm. Any animal except birds and mammals are ectotherms

There seem to be very few animals that don't have specialized mouth parts. Birds have all kinds of beaks to suit their needs for fishing, draining water from algae (that's what the "teeth" on a gooses bill are for) cracking hard shells, or tearing meat from roadkill. Rodents have teeth that continue growing so they can gnaw on as many seeds or as much wood as they need to. Many insects have jaws that let them cut through plants or flesh, while a proboscis lets butterflies drink from flowers and lets mosquitoes drink your blood. Even generalist fish have a way to flair their gills out in a certain way to suck in water and food, but the parrotfish has beaklike teeth that allow it to scrape off bits of coral, and stingrays have a downward facing mouth with hard molars that let it crush the hard shells of crustaceans and clams. Snails have mouthparts unlike anything else in the animal kingdom, that let them pull bits of algae or debris off of surfaces.

The firefly has had to make a number of adaptations in order to survive. The firefly has had to create a light to see at night for example.

You'll have to specify what kind of squid you're wondering about. There are many types of squid in the world that come in wide variety of sizes

There are squids in the Arctic

in the deep oceons of indonisa

A great white shark (as in Jaws) can certainly swallow a human. In addition, sperm whales feed on giant squid, octopus, and even rays; they are usually about 59 feet long, and weigh nearly a ton, so it's possible that they could swallow a human as well.

Some types can, like the blue ringed octopus. Others kill by strangling their prey etc.

A scallop is a bivalve mollusc which lives in a shell. A squid is a free swimming cephalopod.

well, an octopus has a diet that consists of small fish, snails, crabs, and clams. they can squeeze all of the liquids in their prey out. then after they flush the liquids out, they slowly eat it through the mouth that is underneath it's body

It acts like sense and taste organ for the lobster.

In the middle of the day because all fish are feeding but some fish feed on different food ex. Carp in day they like bread On the top of the water but night they eat boilies with tactical rigs

clams, oysters and scallops are organized into the group called bivalves. they are two-shelled, slow moving organisms

Echinoderms can only be found in water, as they are aquatic.

Some characteristics of Echinoderms are:

Hard Skin, have arms or spines, have 5 body parts, organs found towards centre of body.

Examples: Star Fish, Sea Cucumber, Sea Urchin

1-2 years, on average

Cnidereans have pressure-sensitive poison glands called nematocysts that are usually on their tentacles. When their [prey] touches these nematocysts, small "fangs" inject poison into the [prey]. The poison in the nematocysts can paralyze or even kill small animals. Once the prey is subdued, the tentacles pull the prey towards the mouth.
