Octopus

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.

Their diet typically consists of small crab and shrimp, but they may also feed on fish if they can catch them. They pounce on their prey, paralyze them with venom and use their beaks to tear off pieces. They then suck out the flesh from the crustacean's exoskeleton.

Because an octopus really hasn't got a "body", it only consists of head and arms. Much of the stuff that we have in our chest and belly (like the stomach) the octopus has in its "head".

Ringed seals eat invertebrates and fish like cod, squid, shrimp, and crustaceans.

Adults feed on crabs, clams, snails, small fish, and even other octopi. They use sharp parrot-like beaks to crush the shells of their prey. Newly hatched octopi are small enough to hide among plankton (small or microscopic organisms including algae and protozoa), so their food, equally small, consists of copepods and larval crabs.
