Abalone is a single-shell mollusk in the ocean, with only half a shell. The shell is thick, flat and wide, and its shape is somewhat like a human ear, so it is also called "sea ear". The spiral part only leaves traces, accounting for a small part of the whole shell. There are nine holes in the edge of the shell, from which seawater flows in and out, and even abalone depends on it for breathing, excretion and fertility. So it is also called "nine-hole snail". The shell surface is rough with dark brown patches, and the inner surface presents blue, green, red and blue pearl luster. Fresh abalone is shelled, marinated for a period of time, then cooked, eviscerated and dried. It is delicious and nutritious. "Abalone, ginseng and tripe with wings" are precious seafood, and abalone ranks first among sea cucumber, shark's fin and tripe with fish. Abalone shell is a famous Chinese herbal medicine. Abalone is also called Senecio scandens in ancient books. It has the effect of improving eyesight, hence the name. Concha Haliotidis also has the effects of clearing away heat, calming the liver and calming the wind, and can be used to treat hand-foot spasm and convulsion caused by dizziness and fever. There are about 90 kinds of abalone in the world, and their footprints are all over the Pacific Ocean, Atlantic Ocean and Indian Ocean. The abalone produced in Bohai Bay in China is called Haliotis discus hannai, which is relatively large. Abalone produced in the southeast coast is called Haliotis diversicolor, and the individual is small; Haliotis diversicolor and Haliotis diversicolor produced in Xisha Islands are famous edible abalone. Because the natural output is very small, it is expensive. Now all countries that produce abalone in the world are developing artificial farming. In 1970s, abalone seedlings with variegated colors were bred in China, and artificial breeding was successful. The body of abalone is covered with a thick calcareous shell. Its shell is a right-handed spiral shell with an ear shape. The literal translation of its Latin scientific name can be called "sea ear" because its shell is shaped like the edge of an ear.

Therefore. The single-walled shell of abalone is hard and right-handed, and its surface is dark green and brown. The purple, green and white colors on the inside of the shell complement each other, just like gems.
In addition, there are a series of spiral protrusions on the shell of abalone, which gradually increase from the top of the shell to the ventral surface. Some of these protrusions penetrate into holes near the end of the spiral layer, and the number of holes varies with different types. There are 4-5 Haliotis discus hannai in northern China and 7-9 Haliotis diversicolor in southern China. China named abalone "nine-hole snail" in ancient times, which is derived from this feature.
The soft part has a big flat meat foot. The soft part is oval, yellow and white, as big as a tea bowl and as small as copper coins. Abalone is attached to rocks by this thick foot and flat sole surface, and crawls in reefs and caves. The adhesion of abalone meat feet is quite amazing. An abalone with a shell length of 15 cm has a foot suction of 200 kg. No matter how violent the storm comes, it can't be lifted. When catching abalone, you can only shovel it down or turn it over or even smash its shell with lightning speed.

The head of abalone is very developed, and its two tentacles are very thin and long when stretched. There is a short protrusion on the back of the antenna base with eyes at the end. There is a head leaf between the two antennae, a kiss extending forward on the ventral surface of the head leaf, and the sun at the front end of the kiss. There is a powerful tooth tongue in the mouth, which is a unique organ of many shellfish. It's a chitin belt with many rows of small teeth, which are shaped like a file. Shellfish use these small teeth to scrape and grind food. Generally speaking, herbivorous species have many small teeth and round tips, while carnivorous species have few small teeth but great strength, and their tips often have hooks or thorns. Abalone is a herbivore, so it has many small teeth on its tongue.
Abalone's feet are particularly thick and divided into upper and lower parts. There are many tentacles and hills on the foot to feel the external situation; The lower foot is oval when stretched, and the abdomen is flat, which is suitable for attachment and crawling. We eat abalone mainly by eating the muscles on its feet.
The mantle of abalone has the same shape as the shell, covering the whole back of the body. Different from the shell, there is a crack on the right side of the abalone mantle, which is equivalent to the hole on the edge of the shell, and there are tentacles on the edge of the crack. When abalone moves, these tentacles will protrude from the shell hole, which is the function of the four senses of taste. Cracks at the edge of the mantle are the characteristics of primitive gastropods, such as slit snails, famous red Weng Rong, keyhole snails and so on.
