The types of shells are tiger-spotted shell, oyster, oyster, snail, clam, scallop, mussel, Bai Bei, razor clam and so on. Details are as follows:

1, tiger scallop

Tiger shell, also known as tiger shell, black star snail and tiger shell, is distributed in Taiwan Province Province, Hainan Island and Xisha Islands. Shells are large, oval and strong. The surface of shells is smooth, just like the brightness of porcelain. The depth of color is related to habitat. Generally white or light yellow, there are many brown or dark brown spots of different sizes, which are very similar to the spots on the tiger and leopard, hence the name. The shell mouth is long and narrow, the front part is slightly wider, and the inner and outer lips are all toothed, about 25 pieces. Common warm-water species in the South China Sea often inhabit coral reefs with a water depth of several meters. Omnivorous mating and spawning are mostly carried out in spring. Eggs are usually laid in coral caves, empty shells or other miserable hiding places. Eggs hatch in oocysts, and within 1-2 weeks, young shellfish are formed.

2.oysters

Oysters are commonly known as oyster seeds and oysters. Worldwide, China is rich in oyster resources and is the hometown of oysters. The bivalve mollusks have different shapes, rough surfaces and dark gray colors. The middle of the upper shell is convex, and the lower shell is close to other objects, which is larger than the upper shell and has a very flat and smooth edge. The inside of the shell at the top and bottom is white and smooth. Distributed in temperate and tropical coastal waters.

3.sweet snail

Sweet snail, also known as rattlesnake and golden snail. Produced in the Yellow Sea and Bohai Sea, mainly distributed in Guangdong, Fujian, Liaoning, Shandong and other regions. It belongs to gastropod mollusk, with a slightly diamond-shaped shell edge and a large, thick and hard shell. The chassis is about 10 cm high and has 6 layers of silk threads. The color of the shell is flesh, the surface is brown, and it has a carpet-like skin. The shell has a large mouth, apricot color inside and pearl luster. This is unique to China, and it is produced in the Yellow Sea and Bohai Sea.

4.clams

Meretrix meretrix is a bivalve mollusk. It has two hard and thick shells, which are slightly quadrangular, the left and right shells are equal, the top of the shell is slightly bent forward, the middle of the rear edge of the shell is slightly topped, the middle of the shell surface is expanded, and the front and rear edges and near-abdominal edges are sharply contracted, and the front and rear edges are ribbed, aborted and cloud-like hearts. The growth line of the shell surface is obviously rough, forming an uneven concentric ring line. Shells have shells, the upper part is white or lavender, the ventral surface is yellowish brown, and the ventral edge is often accompanied by black stripes. The inside of the shell is gray. Living in shallow mudflats, distributed along the coast of China. Clam meat is tender, delicious and nutritious.

5. scallops

Scallop, also known as mussel, is a marine bivalve mollusk of the genus Scallop. It has a straight shell with a butterfly hinge, wings extend from both ends of the butterfly hinge, and the shell is smooth or luminous. Ribs are smooth, scaly or tuberculous, bright red, purple, orange, yellow to white. The lower shell is lighter and smoother. There are large adductor muscles. World distribution from intertidal zone to deep sea. The main nutritional component of the edible part of scallop is protein.

6.mussels

Mytilus, also known as sea rainbow, has a dark brown shell, and two crustaceans live on coastal rocks. Distributed in the Yellow Sea and Bohai Sea coasts of China. The shell is wedge-shaped, with a tapered front end and a round back end. Generally speaking, the length of the shell is 6 ~ 8 cm, and the length of the shell is less than twice the height of the shell, and it is thin. The top of the housing is located at the front end of the housing. The two shells are equal and symmetrical, with purple luster on the shell surface, thin and obvious growth lines and annular growth from the upper part.

7. Bai Bei

Bai Bei, also known as Baihai and Beizi, lives under coral reefs and rocks in the middle and low tide zone and is distributed in the South China Sea. The shell is slightly oval, with strong texture, the center of the shell back is raised, and the sides are hard and thick. The back of the chassis is equivalent to 1/3 of the chassis length. Bilateral sudden expansion forms tumor-like processes. The shell is smooth, grayish yellow or yellowish white, with blue-gray back and fine lines in white, mostly orange with fine lines, gray back or blue-gray, and a few have three unclear dark bands and brown spots.

8. razor clam

Sole, a kind of mollusk, is a kind of marine shellfish with left and right shells. The shell is crisp and thin, long and flat. There is a light green thin skin on the surface. Starting from the belly end of the upper part of the shell, it penetrates into powder and turns white, forming an inclined groove. Soft sediments living near estuaries and shallow inner bays injected with a small amount of fresh water depend on sufficient caves for their livelihood.
