Squid

yes they do have tentacles , surrounding their mouth.

They use their tentacles to sting their prey.

-------

In addition to envenomating prey, cnidarians use their tentacles to bring their food towards their oral cavity and to provide defense against predators. Sessile cnidarians can also use their tentacles for locomotion, using sticky nematocysts for adhering to the substrate and then pulling themselves along a surface by retraction of those tentacles.

Certain box jellyfish species (notably, Carybdea sivickisi) use their tentacles during courtship behavior- the males use them to hold onto a mate, and the females use them to ingest the presented sperm package (spermatophore) into their cavities in proximity to their eggs.

Some small jellies also use their tentacles to hold onto eel grass for reasons that are yet to be fully understood, but probably are related to camouflage.

yes yes it depend if you fish to much because the pther animals which survive on fish should at least get some fish can survive on their fish diet yes yes it depend if you fish to much because the pther animals which survive on fish should at least get some fish can survive on their fish diet

yes they eat large meaty foods like small pieces of fish, squid, shrimp, and live goldfish.

The structure that mollusks use to grasp food is called a foot. The scientific name of this appendage is the radula.

The scientific classification for a Giant Octopus is as follows:

Kingdom: protista

Phylum: Mollusca

Class: Cephalopoda

Order: Octopoda

Family: Octopodidae

Genus: Enteroctopus

Species: Enteroctopus Dofleini

I don't know. Go on Google, Dogpile, and research. I'm sure you'll get a big list.

After they are a year old, mollusks, such as oysters, will spawn as males. The next year they will spawn as females. When the waters grow warmer, it will cause a few of the oysters or other mollusks in a bed to spawn, and once these few spawn, it prompts the rest of the colony to spawn. Females are capable of producing up to 100 million eggs per spawn cycle, although that doesn't necessarily mean that that number will be spawned each time. Once the egg is fertilized, it will soon grow into a larvae. The larvae will then attach onto the shell of an adult oyster, or somewhere else they can attach, and grow into an adult oyster.

They are all molluscs.

Well, honey, technically speaking, it is possible to eat the innards and brain of an octopus. As for whether anyone has tried it, well, let's just say people have been known to get a little adventurous with their seafood choices. Just remember, if you're gonna dive into some octopus innards, make sure you know what you're getting yourself into!

They eat planktonic crustaceans and small schooling fishes.

yes

Giant squids are generally bigger than portuguese man of wars, but portuguese man of wars can actually grow much bigger than the giant squid. Giant squids are up to 50 ft in length, while portuguese man of wars tentacles can reach up to 165 ft. That is slightly more than three times the length of the giant squid.

--Because squid are spurt swimmers, it is dangerous to their safety to keep squid. They will often jet into the sides of the tank in which they are kept, and if this happens enough they can severely injure themselves. Very few squid are dangerous, the exceptions being those larger than humans, such as the Humboldt, Giant, and Colossal squids. You could illegally keep a squid, but they are very difficult to care for. Cuttlefish and octopods would be better alternatives.--

I have been a marine hobbyist for 25 + years. In the extra large public aquarium, it is a known fact that a Moray of similar size to any breed of shark will kill that shark. In fact, I believe the count is something like 120 to O. In favor of the Moray Eel. As for the wild though, I have witnessed first hand during my dives too that a large Moray Eel can more than hold it's own with the largest of sharks. I once witnessed a Giant Moray grab the tale of a rather menacing looking 7-8' Tiger Shark. The Tiger Shark's tail was shredded before our eyes. My only wish was that I could have captured that with underwater video. So please, if you have the ability to house those two large animals, please do not mix them together in the same tank. The shark will die a cruel and senseless death. The Tiger Shark swam out into the blue and probably into the mouths of it's own kind, since it was bleeding from the Eel encounter. To our surprise the Giant Moray then turned it's sights on my dive team. Swimming up and mouthing our regulators and mask. Not one of us sustained a wound. We were sure the Giant Moray mistaken our team for another team that evidently befriended the beast.

gripping prey and bringing it closer to the squid

Bilateral (meaning that it is symmetrical only is divided alone onle specific line. Radial symmetry means that the object can be symmetrical when divided along more that one different line.)

PS The previous awswer is,as far as I'm aware,100% wrong.

So long as no one picked at it on the way from the store, it is still one pound.

Squid (of any size) have beaks, which they use to bite off their food, which they then swallow.

it usually lives in tropical places

No. In order for a sea animal to be considered a kosher species, it must have both fins and removable scales (Deuteronomy ch.14), as well as a bony (not cartilaginous) skeleton. Squid has none of those features, hence it is not kosher.

Names for squid in modern scientific Latin tend to involve the word teuthis, which is originally Greek. This word isn't attested in ancient Latin. There was a mythical many-armed creature called the arbor ("tree") because its arms were fancied to resemble the branches of a tree, which may or may not be a reference to a sort of squid.

It's hard to describe. It is wet and sort of slimy. It is strong and has lots of muscles, but it will slip through your fingers if it wants to. The suckers will grab on, but they don't hurt.
