Octopus

Yes, an octopus can regrow an arm that gets torn off.

They are not the same at all. Squid have for example red blood awhile octopuses have blue blood. They are categorized in a whole different species. Though they do look almost the same they are still not. Squid can be found in deeper depths than octopuses, and they don't have the same behaviors.

Octopus is a common dietary item in several East Asian countries including China, Taiwan, Japan, and Korea. It is also eaten regularly in Hawaii, since many popular dishes there are Asian in origin. Octopus is also a common food in Mediterranean cuisine and Portugues cuisine.

It depends on the type of octopus but it could be up to 1500 babies.

an octopus has three hearts

well one of the blue ringed octopuses predators is the moray eel.

The blue-ringed octopus, as well as any octopus, is in the phylum of Mollusca. All octopi are aditionally in the class Cephalopoda and the order Octopoda. The Blue-ringed octopus is additionally in the genus Hapalochlaena.

They are commonly called suckers.

This is a very debated issue, but I do not believe so. There are some freshwater jellyfish however. I do believe that ther is such a thing, my biyfriend and I were at the river in Middleton Idaho and found 2-3 dozen of them! Granted they were dead but nobody would have dumped there because we were too off shore for somebody to da that and they were not cooked either

Sea creatures are usually measured by length, rather than by height, since they are generally not found in a standing position, unlike land animals. On average, an octopus is several feet in length if you count the tentacles. The central body mass, other than the tentacles, is typically about ten inches in diameter.

The average life span of octopuses ranges from six months to 4 years. Since the Dumbo octopus is a deep-sea animal, little is known about their lifespan, but it is assumed that it would be longer. They skip the vulnerable larval stage and deep-sea critters seem to be longer lived.

yes they can but they cannot eat the shell

OCTOPUS HAVE A BILATERAL SYMMETRY BECAUSE IF IT IS CUT IN HALF THE OTHER SIDE WILL BE JUST LIKE THE OTHER IT WILL BE LIKE A MIRROR VIEW

Baby octopuses look just like an octopus right out of the egg.

Yes, it is actually a common food in some countries.

It can spray ink. Also, some species have rings that can glow to scare off attackers.

probably but if it is no then hide it from the feds lol

They are not. Filter feeders are things like blue whales that passively filter plankton from the water as they swim. Octopuses are predators that hunt other creatures living on the sea floor.

A devilfish octopus eats crabs and other things.

A dumbo octopus (an octopus of the genus Grimpoteuthis) has earlike fins sticking out of its body, but a regular octopus does not. The dumbo octopus also has webbing between its tentacles.

Humans eat octopus in many cultures. The arms and sometimes other body parts are prepared in various ways, often varying by species.

Octopus is a common ingredient in Japanese cuisine, including sushi, takoyaki, and akashiyaki.

In Korea, some small species are sometimes eaten alive as a novelty food. A live octopus is usually sliced up, and it is eaten while still squirming.

There is no such thing as a tree octopus. It is a fictitious organsim, just like the jackalope of the western United States.

Yes, more or less. It comes from the Greek okto "eight" and pous "foot".

Octopuses are mostly carnivores, although some species are omnivores. For the most part an octopus feeds on clams, mussels, shrimp, crab, and things of those size.
