What kind of animal is an octopus, is it a mollusk or a fish?

Octopuses are widely distributed in tropical and temperate seas around the world, and are found along the coasts of both northern and southern China. There are about 650 species, varying greatly in size. Octopuses are highly intelligent and can even use tools. Through gene decoding, scientists have found that octopuses possess a set of genes similar to those of humans, which explains why octopuses have learning ability. Let's take a look below at what kind of animal an octopus is!

What kind of animal is an octopus

The octopus is a marine mollusk. The octopus belongs to the phylum Mollusca, class Cephalopoda, order Octopoda, family Octopodidae, genus Octopus, and is the general term for animals of this genus. Because it has eight arms on its head, with membranes connecting the arms, varying in length, and two rows of sessile suckers on the arms, it is called "eight-armed," and it is not a fish.

What food do octopuses eat?

The octopus is a carnivorous marine mollusk that feeds on bivalves and crustaceans (shrimp, crabs, etc.), and some species feed on plankton. This is not a matter of whether it likes to or not, because the stable structure of myoglobin is a necessary condition for octopuses to survive in the deep sea. Giant octopuses will fight to the death with sperm whales just to compete for astaxanthin resources. Astaxanthin is the strongest antioxidant and is a necessary condition for ensuring the stable structure of myoglobin so that it is not oxidized.

Is the octopus highly intelligent?

The octopus has the ability of "conceptual thinking" and can solve complex problems on its own. It is precisely this ability that gives it the skill of walking on two legs. Through further research, scientists have also found that octopuses live alone from the moment they are born. A small octopus needs only a very short time to learn the skills it should have, and unlike most animals, learning is not based on instruction from elders. Although their parents pass on some abilities to them, the small octopus develops its own ability to solve new problems through learning on its own how to hunt, camouflage, and find better dwellings. At the same time, this eight-legged species can move coconut shells and use them as its own armor, which is the first case of an invertebrate using tools.
