CATDOLL : CATDOLL: What does a cuttlefish look like?

1. Mouth: top center.

2. Eyes: One pair of empty and vertical limbs, on both sides.

3. Olfactory pit: behind the eye, near the edge of the mantle.

4. Infundibulum depression: The depression on the ventral side of the head where the infundibulum is attached.

5. Foot: divided into wrist and funnel.

6. Funnel: specialized foot, ventral surface; the channel for movement, excretion of excrement, reproductive products and ink.

7. Tentacles: The base is thick, the top is pointed, and there are suckers on the inside. There are 10 tentacles in total, and there is a pair of tentacles between the 3rd and 4th pairs of tentacles that are specially used to catch large food. They are relatively narrow and can be completely retracted into the tentacle capsule at the base. There is usually a very long handle on the tentacle, and the top of the handle is tongue-shaped, called the tentacle spike, which has suckers inside and sometimes hooks, mainly used to grab food.

Additional information

Squid ink mainly contains elements such as water, melanin, mucopolysaccharides and potassium, as well as a small amount of toxins. This toxin has little harmful effect on the human body and will be decomposed and destroyed during high-temperature heating. Therefore, squid ink can be eaten after heating, but it is not recommended to eat it raw.

The mucopolysaccharides rich in squid juice can inhibit the growth and reproduction of cancer cells and have a certain anti-cancer effect.

Cuttlefish (squid) is shown below:

The body of cuttlefish can be divided into three parts: head, foot and trunk. The trunk is equivalent to the visceral mass, covered with a muscular mantle and with a calcareous inner shell.

The head is located at the front of the body and is spherical. The top of the head is the mouth, surrounded by oral membranes and 5 pairs of arms. There is a pair of well-developed eyes on both sides of the head, with a complex structure. There is an oval pit below the eyes, called the olfactory pit, which is the olfactory organ, equivalent to the olfactory organ of gastropods, and is a chemical receptor.

The feet have been specialized into arms and funnels. There are 10 arms, arranged symmetrically, with the first pair in the middle of the back, followed by the 2nd to 5th pairs ventrally. The fourth pair of arms is particularly long, with the ends swollen and tongue-shaped, called tentacles, which can be used for hunting and can be retracted into the tentacles.

Additional information

The orientation of the squid's body is based on its living conditions in the water, with the head end being the front, the trunk end being the back, the side with the funnel being the abdomen, and the opposite side being the back. However, based on the comparison between the mollusk's system and the squid's morphology, the front end should be the abdomen, because the feet are on the abdomen, and the back end is the back. The back side is the front, and the abdomen is the back. This is the squid's morphological position, but for the sake of simplicity in observation and description, the former orientation is often used.

The squid has a flat and soft body, which is very suitable for living on the seabed. The squid moves quickly and can quickly escape when it encounters an enemy attack. It not only escapes quickly, but also hunts faster. The squid can change its color by adjusting the size of the pigment sac in its body to adapt to the environment and escape from the enemy.

The cuttlefish has an ink sac in its body, which contains thick black ink. When it encounters an enemy, it quickly sprays out the ink, dyeing the surrounding sea water black to cover its own escape.

Cuttlefish have millions of red, yellow, blue, black and other pigment cells in their bodies, which can react within one or two seconds. They are masters of color change in water.

Cuttlefish usually move slowly in a wave-like manner, but when they encounter danger, they will leave their enemies behind at a speed of 15 meters per second. Some squids can move at a maximum speed of 150 kilometers per hour.

Cuttlefish, also known as cuttlefish, squid, or cuttlefish, is a member of the order Sepiidae, cephalopoda, and molluscs. When a cuttlefish encounters a strong enemy, it will "spray ink" as a way to escape and wait for an opportunity to leave, hence the names "squid" and "cuttlefish". There are small pigment sacs in its skin that change color and size with its "emotions". The cuttlefish can jump out of the sea and has an amazing ability to fly in the air.

1. Cuttlefish is a squid

Some people may be unfamiliar with the name of cuttlefish, but they are familiar with squid. Cuttlefish is also known as cuttlefish or squid, and it is mainly famous for its ink spraying as a way of escape. As a specialty dish along the Traveler Sea, cuttlefish will be made into a variety of dishes, but each dish has a unique taste.

2. Cuttlefish is cuttlefish

Cuttlefish is another nickname for cuttlefish. The head of cuttlefish is spherical at the front of the body. There are five pairs of arms on the periphery of it, and a pair of well-developed eyes on both sides of the head. The structure of the eyes is relatively complex. There is an oval-shaped sensitive pit under the eyes, which we call the olfactory organ. There are many creatures in this world that rely on smell to judge whether the surroundings are safe, and squid is one of them.

3. Cuttlefish is also known as eye fish

Cuttlefish like to live in the deep sea, but in spring every year, they start to swim to the deep sea and lay eggs in shallow bays. Because the body of the cuttlefish is very flat and soft, it is suitable for living on the seabed. Although the cuttlefish usually moves slowly, once it encounters danger, it will leave the enemy behind at a speed of 15 meters per second. In addition to running away quickly, the cuttlefish is even faster when catching prey.

If you have seen a real cuttlefish, you will know that its body is like a rubber bag, and it has a boat-shaped lime hard sheath. This sheath should not be underestimated, as it contains all the organs of the cuttlefish. In addition, the peak season for cuttlefish is from February to March in the South China Sea, from April to May in the East China Sea, from June to July in the Yellow Sea, and from October to November in the Bohai Sea. The cuttlefish eaten in these seasons are very fresh.

1. Cuttlefish is a squid

In real life, many people still can't tell the difference between cuttlefish and squid. In fact, cuttlefish is squid. When we studied biology, we knew that it was a mollusk. Although cuttlefish is a mollusk, it is a shellfish. The most important thing is that cuttlefish is very delicious when made into dishes, and it is precisely because of this that it is favored by the public.

2. Squid is cuttlefish

In addition to being called cuttlefish, cuttlefish is also called squid, cuttlefish, eyefish, etc. So it is understandable that you don't know that cuttlefish is squid. In China, the cuttlefish or squid we call are mostly the two species of squid, the needleless squid and the golden squid, which are mainly produced in the East China Sea. Due to the difference in species, there are certain differences in taste and price, but their deliciousness is irreplaceable.

3. Cuttlefish is also called squid

The reason why the cuttlefish is also called squid is mainly because it can spray ink when it encounters danger. This ink is black, and when the enemy is still surrounded by the ink, the cuttlefish takes this opportunity to escape. In fact, in addition to this ability, the cuttlefish has an even more amazing flying ability, and sometimes it can even jump out of the sea to achieve a short flight.
