Octopus, cuttlefish and squid are the three major molluscs in the ocean. They look similar but different. Today I will teach you how to distinguish them.

Octopus

The octopus, also known as the octopus, the octopus, the octopus, and the dead cow, is one of the largest molluscs in the ocean. The body is sac-shaped and has a thick fleshy membrane on its surface that can protect it. They have eight tentacles, which are very sensitive and can be used to sense their surroundings and to hunt prey. Octopuses can secrete a special mucus to evade predators or attract prey.

Octopus has no bones and can be eaten whole, but its thick feet are more commonly eaten. Octopus can enhance immunity, improve liver function, and improve vision.

Cuttlefish

Cuttlefish, also known as cuttlefish, squid, and cuttlefish, usually live in shallow seas and deep seas. Their bodies are elongated and their heads have a pair of antennae that they use to sense their surroundings. The cuttlefish has fleshy fins on both sides of its body and a total of 10 arms, 8 of which are short. Cuttlefish can spray a black liquid to disrupt the senses of predators and escape danger. In addition, cuttlefish can adapt to their environment by changing their color and shape.

Squid has hard bones, which have the functions of inhibiting gastric acid, astringent and hemostasis, and anti-viral. When handling it, pay attention to the black ink inside it. The ink fountain must be taken out, otherwise it will be a dark dish.

Squid

Squid, also known as squid, squid, and sea squid, has a slender body and is distributed in both shallow and deep seas. Their body consists of ten thoracic arms, two suckers, a tentacle and an ink sac. Squids spray water jets or ink to escape predators or confuse prey. They can also, like cuttlefish, adapt to their environment by changing their color and shape.

Squid has cartilage and mainly eats the tubular body (cut into squid rings or squid flowers) and squid tentacles. Long-term consumption can prevent anemia, lower cholesterol and improve vision. Squid with seeds is also called "cake squid" in the south. The white particles in the belly of the squid are its eggs. When cooked, they are white and taste a little pink, but they taste great.

Distinguishing method

1. Number of arms and legs: Squid and cuttlefish have ten arms; octopus has eight arms (octopus).

2. Fins: squid has two pointed terminal fins; cuttlefish has short fins surrounding its body; octopus has no fins.

3 Inner shell: squid has an elastic, translucent inner shell; cuttlefish has a hard calcareous inner shell; octopus has no inner shell.

4. Pupil shape: cuttlefish W-shaped; squid crescent-shaped; octopus straight-shaped.

5. Edible parts: squid and cuttlefish are body parts; octopus is mainly the arms and legs.

6. Body shape: Squid is slender; cuttlefish is more rounded; octopus often appears in the form of red, thick arms and legs.
