What does an octopus look like?

Octopus Appearance:

The body of an octopus is short and oval, sac-shaped, and finless. The boundary between the head and the body is not obvious. The head and body of an octopus are about 7-9.5 cm long, with large compound eyes and 8 retractable arms. Each arm has two rows of fleshy suckers. The arms of a short octopus are about 12 cm long, those of a long octopus are about 48.5 cm long, and those of a true octopus are about 32.5 cm long.

The base of the arm is connected to a webbed tissue called a skirt, with a mouth in the center. The mouth has a pair of sharp horny palates and a file-like tongue, which are used to drill through shells and scrape the meat. It is medium-sized and widely distributed in tropical and temperate waters around the world. It lives in caves or crevices on the rocky seabed and likes to hide.

Reproduction method:

Octopuses usually breed in the ocean in spring and autumn, when the seawater temperature is around 16°C. Octopuses like to lay eggs in snail shells, so you can use a rope to penetrate the snail shells and sink them to the bottom of the sea, and then catch them on time. In autumn and winter, they often live in burrows in the muddy sand in deeper seas.

Octopuses are dioecious. The male has a specialized arm, called the peduncle arm or coaptation arm, which is used to place the spermatophore directly into the mantle cavity of the female.

During the breeding season, female octopuses lay eggs, about 0.3 cm long, with a total of more than 100,000 eggs, under rocks or in caves. During the incubation period, the female stays by the eggs, cleans them with a suction cup, and stirs them with water. After the female octopus lays eggs once, it takes 4-8 weeks for the larvae to hatch. The shape of the juvenile octopus is similar to that of the adult but smaller. After hatching, it needs to drift with the plankton for several weeks before sinking to the bottom of the water to hide.

The octopus's body is short oval, sac-shaped, and finless; the boundary between the head and the body is not obvious. The octopus's head and body are about 7-9.5 cm long, with large compound eyes and 8 retractable arms on the head.

Each arm has two rows of fleshy suckers, the arm of the short octopus is about 12 cm long, the arm of the long octopus is about 48.5 cm long, and the arm of the true octopus is about 32.5 cm long. It usually crawls with its arms, and sometimes swims by stretching the membrane between its arms. It can hold other objects firmly and use the macro funnel under its head to spray water for rapid retreat.

Octopus Notes

Octopus is a cold food, so people with weak spleen and stomach or poor physical constitution should try to avoid eating octopus.

Also, octopus and beer cannot be eaten together, because octopus contains a lot of protein, and protein contains a lot of purine. Drinking beer may lead to an increase in the amount of purine in the body, and some gout symptoms may occur. If the two are eaten together, it may cause indigestion. Also, octopus should not be eaten together with some cold foods, such as watermelon, which may increase the coldness in our body.
