The octopus, the most famous representative of cephalopods, has a short, soft body, oval at the back. The mouth opening is located where its tentacles meet, and the anal opening opens under the mantle. The robe resembles a wrinkled leather bag. The octopus's mouth is equipped with two powerful jaws, similar to the beak of a parrot. There is a grater in the throat that helps to grind food. The head bears eight long tentacles - “arms”.
In males, one tentacle is modified into a copulatory organ. The “hands” are connected to each other by a thin membrane and equipped with suction cups. On all eight tentacles of an adult octopus there are about 2000 of them, each of which has a holding force of about 100 g. On each “arm” there are up to 10 thousand taste buds that determine whether an object is edible or inedible. The eyes are large, with a lens similar to that of a human. The pupil is rectangular. There is no hearing. The octopus breathes through gills, but without harming its health, it can be out of water for a short time. The brain is highly developed and has a rudimentary cortex. The octopus has three hearts: one (the main one) drives blue blood throughout the body, and the other two - gills - push the blood through the gills.
The common octopus has the ability to change color to adapt to its environment. This is explained by the presence in his skin of cells with various pigments that, under the influence of impulses from the central nervous system, can stretch or contract depending on the perception of the senses. The usual color is brown. If the octopus is scared, it turns white; if it is angry, it turns red.
On average up to 90 cm in length (including tentacles), the maximum length in males is up to 1.3 m, in females - up to 1.2 m. Weighs from 4.5 to 7 kg, maximum weight 10 kg. Lifespan: Rarely exceeds 4 years, average 12-24 months.
It lives in all tropical, subtropical seas and oceans (with a salinity of at least 30%), from shallow water to a depth of 100-150 m. It prefers rocky coastal zones, looking for caves and crevices in the rocks for habitat. It is eaten by dolphins, sea lions, whales, seals, moray eels, eels, sharks, and birds. The octopus itself is a predator, hunting while sitting in ambush. Eats mollusks, snails, crustaceans, fish, plankton. The common octopus captures prey with all eight tentacles, and bites the victim with its beak, holding it with its suction cups. In this case, the poison of the salivary glands from the throat and mouth enters the wound.

When purchasing frozen octopus, you need to pay special attention to the appearance of the ice. The presence of white specks or crushed pieces of ice indicates that the product has been frozen several times.
