First, the squid
Squid is distributed in the northern coast of the Japanese archipelago, including the Yellow Sea and other sea areas. The body is small, the trunk is slender, the back end is pointed, and the fins are narrow, which are located at the whole edge of the trunk. The male body is slender and conical, and the second pair of wrists is more than twice the length of the other wrists. The female body is slightly fat, short and nearly oval, and the length of each wrist is very small. There are also differences between males and females in the inner shell. The male is longer, about 6 times the width, and the female is shorter, about 4 times the width.
Second, the squid
The cuttlefish, also known as cuttlefish and mullet, is distributed in the Bohai Sea, the Yellow Sea, the East China Sea, the South China Sea, the Japanese Islands and the Philippine Islands. It is one of the important economic species in the world's sepiidae, and its annual output ranks second among the world's sepiidae species. The squid with the largest output in the Japanese Islands and the most economic value in the northern waters of China was once called one of the four traditional fisheries in China together with large yellow croaker, small yellow croaker and hairtail, and it is an important fishing object.
Third, squid
Squid is also called squid, squid, soft fish, etc. The mollusk Cephalopoda is an eye-opening suborder, with a slender body and a long cone shape. There are more than a dozen touching wrists, two of which are long, with a sucker at the front end of the touching wrist, and a horny toothed ring in the sucker. When preying on food, it is entangled with the touching wrist to swallow it, and it likes to gather in groups, especially during mating and spawning in spring and summer.
Four, the king squid
The king squid, usually inhabiting deep-sea areas, is mainly produced in the North Atlantic Ocean and the North Pacific Ocean. It is estimated to be about 20 meters long and is one of the second largest mollusks and invertebrates known at present. Living in the deep sea, there are legends of sea monsters in the maritime civilizations of many countries, such as Clegan, whose looks are very similar to those of squid. Modern people also have some fragmented understanding of the king squid.
Five, the flame squid
Fire squid, also known as fire cuttlefish, fire squid, etc., is a kind of squid that lives in tropical waters of Indonesia, New Guinea, Malaysia and northern Australia, and it is a kind of toxic squid. The sediment area inhabiting the bottom of seawater, with a distribution depth of 3 meters to 86 meters, is diurnal, with complex camouflage of pigment cells on the surface, preying on fish and crustaceans.
Six, fluorescent squid
Fluorescent squid is the only species of Cephalopoda Guniformes. Fluorescent squid is an underwater assassin who can use biological light to disguise, and it is the only creature in Cephalopoda that has been proved to have color vision. The fluorescent squid is usually only 7 cm long, and it has complex epidermal light emitters and eyeball light emitters, which are mainly located in the mantle, head, eyes, wrists and other parts, especially in the eyes and lower abdominal cavity. It is a radioactive compound synthesized by itself, and emits cold light with the participation of oxygen, magnesium ions and luciferase.
Seven, spotted squid
Spotted squid is an animal belonging to the genus Spotted Squid in sepiidae, commonly known as Spotted Squid in the Caribbean. It is distributed in the southern part of the Japanese archipelago, Ryukyu Islands, Maluku Islands, society islands, southwestern California Peninsula, Bay of Bengal, Comoros Islands, southern and southwestern ends of Africa, southeastern Argentina, Gulf of Mexico, Buddha and northern South China Sea in Chinese mainland. Its living environment is seawater, and it generally lives on the surface.
Eight, squid
Squid is only 1 cm in length, small and symmetrical, with a flat shape. The outer body is covered with a layer of wrinkled skin called mantle, and the inside is called mantle cavity. The fins around the back end of the body are like a long and narrow lace skirt, and the head has a pair of eyes with complex structure and developed like human eyes, and there are 10 wrist feet. There are many small hooks on the sucker, like cat claws.
Sepiella maindroni
Sepiella maindroni is an annual medium-sized squid with fast growth and delicious meat, which is a popular seafood food in the market. The trunk is shield-shaped, the length of the trunk is twice as long as the width of the trunk, and there are many nearly oval white spots on the back of the trunk. The fleshy fins are narrow at the front and wide at the back, which are located on both sides of the trunk and separated only at the end. It is distributed in the coastal waters of the Northwest Pacific Ocean and the North Indian Ocean. The main fishing grounds are in the coastal waters of China, Zhejiang and Fujian, with a maximum annual output of over 80,000 tons, making it an important economic species in the world.
Ten, flying squid
Flying squid lives in the deep sea, but has a wide range of vertical activities, and often swims in the upper and middle layers, and sometimes even jumps out of the sea. The trunk is conical, very thin and narrow, about 6 times as long as the trunk width, and the back is more thin and concave. The body surface has nearly round pigment spots of different sizes, all of which are small and purple-brown, and are distributed in the South China Sea, Sagami Bay, Christmas Island and the offshore of eastern Australia.
Through the above introduction, we now know the species of squid. The flesh of squid is edible, and the ink in its ink sac can be processed for industrial use. The ink sac is also a medicinal material. The inner shell can be fed to caged birds to supplement calcium, and the viscera of squid can be squeezed into visceral oil, which is a good raw material for tanning.
