CATDOLL : CATDOLL: What is the difference between squid and cucumber?

The differences between black sea cucumber and sea cucumber lie in their origin, appearance, nutritional value, price and use. Sea cucumbers are divided into two categories: light sea cucumber and sea cucumber. Black sea cucumber belongs to the light sea cucumber category. It is smooth and has no meat thorns. Most sea cucumbers are black or black purple. Generally speaking, the nutritional value of sea cucumber is higher than that of light sea cucumber. Among them, the northern sea cucumber produced in the Bohai Bay area (that is, the sea cucumber produced in Shandong coastal areas and Liaoning coastal areas) has the highest nutritional value. In comparison, the nutritional value of black sea cucumber is lower than that of sea cucumber, so it is mostly used for cooking and is cheaper.

1. Different origins



There are many places where sea cucumbers are produced, mainly in Dalian and Jiaodong Peninsula, and Shandong is the main production area. The production area of ​​black sea cucumbers is near Hainan and the Xisha Islands, so they are produced in different places. Due to the different water quality of seawater in different regions, their tastes are slightly different.

2. Different appearance

The surface of the black cucumber is smooth and has no soft spines, so it belongs to the light cucumber category. As for the sea cucumber, it has many soft spines besides the light cucumber. Therefore, the black cucumber only belongs to the light cucumber category, while the sea cucumber has both light cucumber and sea cucumber.

3. Differences in nutritional value



Although they are both seafood, the nutritional value of black cucumber is not as good as that of sea cucumber. Generally speaking, the nutritional value of sashimi is higher, and the content of protein, amino acid and various vitamins contained in it is also very high. Black cucumber is relatively weaker, so we can also distinguish them from the nutritional value.

4. Difference in price

The price of black cucumber is cheaper than that of sea cucumber. Therefore, when we want to eat ginseng but don’t want to pay a high price, we can use black cucumber instead.

5. Different uses



Because the nutritional value of black cucumber is relatively low, it is generally used as food and is more often used in catering. However, the nutritional value of sea cucumber is high. In addition to being eaten, it can also be used as a tonic. Therefore, this is also their own difference.

There are many origins of sea cucumbers, mainly in Dalian and Jiaodong, with Shandong as the main origin. The origin of black sea cucumbers is in Hainan and the Xisha Islands, so their origins are also different. Because the water bodies in different regions are different, their tastes are slightly different. The surface of black sea cucumbers is smooth and has no thorns, so it belongs to the light sea cucumber category. As for sea cucumbers, in addition to light sea cucumbers, there are also some with many thorns. Therefore, black sea cucumbers only belong to the light sea cucumber category, and sea cucumbers have both light sea cucumbers and sea cucumbers.

Many people cannot tell the difference between a squid and an octopus, thinking that they look similar, but they are very different. First of all, they are not animals of the same order. Octopuses belong to the order Octopoda, while squids belong to the order Sepiidae. Their appearance is also very different. Octopuses have eight tentacles, while squids have 10. The body shape of an octopus is relatively soft, while the squid has a hard calcareous shell inside and its body is flat. Squids belong to the genus Sepia of the family Sepiidae, while octopuses belong to the genus Octopus of the family Octopidae. Difference in appearance: Squids have 10 tentacles, which are symmetrical on both sides. Octopuses have only 8 tentacles, but they can retract them at will. Difference in food: Octopuses feed on crustaceans and plankton, while squids can eat fish and mollusks in addition to crustaceans. Difference in IQ: Octopuses are smarter than squids because they have more developed brains.

The difference between squid and cucumber

The real name of the squid is squid, also known as cuttlefish, cuttlefish or cuttlefish. It is an animal of the order Sepiida of the phylum Mollusca, class Cephalopoda. When the squid encounters a strong enemy, it will use "ink spray" as a way to escape and wait for an opportunity to leave, so it is called "squid" and "cuttlefish". There are small pigment sacs in its skin, which will change color and size with the change of "emotion". The squid can jump out of the sea and has an amazing ability to fly in the air. Like squid and octopus, it is a marine mollusk, and none of the three are fish.

Black sea cucumber belongs to the light sea cucumber family, and its body is smooth and has no fleshy spines. Most sea cucumbers are black or dark purple. Generally speaking, the nutritional value of sea cucumbers is higher than that of light sea cucumbers, and the northern sea cucumbers produced in the Bohai Bay area have the highest nutritional value. In comparison, the nutritional value of black sea cucumbers is lower than that of sea cucumbers, so they are mostly used for cooking and are sold at a relatively low price.

The surface of the black cucumber is smooth and has no sharp thorns, while the sea cucumber has a layer of thorn-like substance on its surface.

The nutritional value of thorny sea cucumbers is higher. Compared with black sea cucumbers, it is better for us to choose to eat sea cucumbers on a daily basis.

Black cucumber can only be eaten as a dish, especially the top-quality black cucumber, which has very tender meat. Sea cucumber can be eaten as a health supplement.

The body shape of the black sea cucumber is oval, tall and laterally flattened, with very protruding dorsal and ventral edges.

Then, observe the head of the black sea cucumber. The black sea cucumber has a small head, a short snout, and a small mouth. The body is covered with small round scales, dark brown, and the lateral line is obviously slightly curved.

Then, look at the scales of the black sea cucumber. The lateral line scales at the caudal peduncle of the black sea cucumber are larger and ridge-like, forming a raised ridge, and the caudal fin is deeply forked.

Then, let’s look at the living habits of the black sea cucumber. The black sea cucumber is a warm-water middle and upper layer fish that swims to the sea near the mouth of the Yangtze River every summer.

Then, let’s look at the distribution of black sea cucumber. Black sea cucumber is distributed along the coast of my country, and is also distributed along the coasts of the Korean Peninsula and Japan, South Africa, India, Indonesia, Singapore, Vietnam, the Philippines and other countries.

The real name of the squid is squid, also known as cuttlefish, cuttlefish or cuttlefish. It is an animal of the order Sepia in the class Cephalopoda of the phylum Mollusca.

There are small pigment capsules in its skin, which will change color and size with the change of "emotion". The squid will jump out of the sea and has an amazing ability to fly in the air. Ziwu is abundant in the pure waters of the Korean Bay. It is round and translucent, tender and full of chewiness. It is a top seafood ingredient for Korean barbecue, seafood hot pot, etc. Ziwu is a cooked California small squid (sea hare, pen fish). The one with seeds is called Ziwu, and the one without seeds is called Piwu. Generally, those with thick tentacles do not have seeds, while those with small tentacles have seeds.

Sea cucumbers are divided into two categories: light sea cucumbers and sea cucumbers. Black sea cucumbers belong to the light sea cucumber category. They are smooth and have no fleshy spines. Most sea cucumbers are black or black purple. Generally speaking, the nutritional value of sea cucumbers is higher than that of light sea cucumbers. Among them, the northern sea cucumbers produced in the Bohai Bay area (that is, the sea cucumbers produced in the Shandong coast and Liaoning coast) have the highest nutritional value. In comparison, the nutritional value of black sea cucumbers is lower than that of sea cucumbers, so they are mostly used for cooking and are cheaper. Squid (English name: Inkfish) is an animal of the family Sepiidae in the order Cuttlefish. It mainly lives in shallow waters along tropical and temperate coasts and often migrates to deeper waters in winter. Its body can be divided into three parts: head, foot and trunk. The trunk is equivalent to the visceral mass, covered with a muscular mantle and a calcareous inner shell. The head is located at the front end of the body, spherical, with a mouth at the top, surrounded by oral membranes, and 5 pairs of arms on the periphery. 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 eye, called the olfactory pit, which is the olfactory organ, equivalent to the olfactory organ of gastropods, and a chemical receptor. It mainly feeds on crustaceans, small fish or other mollusks.
